I have been writing for BonneGueule for three years and despite several selections on divers, military watches, dress models... I have never dedicated an article to a quartz watch.
You know, I have a passion for traditional tocantes, I am even very committed to this return to mechanical watches: for their history, for their charm, for the idea of keeping beautiful objects made to live with for decades. us and be passed on, I hope, to future generations.
If I fully assume a clear preference for mechanical watches, do you also know that I also have a collection of vintage electric and quartz watches? Certainly a little more modest in comparison. However, I often look for vintage models that date from the early days of battery-powered watches.
What is a quartz watch?
The principle of the quartz watch is based on the use of an electronic circuit, powered by a battery, which produces a signal. The energy from the battery powers this circuit as well as a quartz resonator
The quartz resonator makes it possible to “filter” the frequencies in order to restore a single frequency: that which will provide excellent stability and precision specific to chronometry. The quartz resonator somehow divides time.
The signal, in other words pulses, will power a Lavet motor
There are two types of quartz watches: the analog watch – three classic hands for example – and the LCD display watch: the latter does not use hands and a traditional dial, the time display is done through the use of liquid crystals.
Unlike many contemporary quartz movements
The G-Shock point
It would be easy to copy for the umpteenth time the storytelling on the birth of the G-Shock in the early 80s and the work of Kikuo Ibe and his “tough team” responsible for creating a watch waterproof to 100 meters, resistant to a fall 10 meters and a battery life of 10 years. But you know me, I'm going to go well beyond and put the G-Shock in the context that determined its birth.
At the beginning of the 1980s, mechanical watches were (very) undermined by the mass arrival of quartz watches during the previous decade. My own father lived through this era in which it became has- been to wear a mechanical watch and the trend was to have a quartz watch.
Seiko and Citizen are spreading on wrists and even traditional brands, heirs of century-old know-how in mechanical watchmaking, are forced to urgently redirect their production towards quartz models in the hope of surviving this surge.
How to resist him? Prices are slashed, demand suddenly shifts in favor of these watches. Except there's a catch. Quartz watches are not that sturdy . A quartz movement itself presents structural fragility in relation to shocks whereas traditional mechanical watches already have anti-shock systems.
As a result, you will understand that there was a slight resistance from certain soldiers, particularly to immediately adopt the quartz watch to replace their solid and proven mechanical watches, as I recall in this article on military watches .
As quartz watches become more widespread, incidents begin to happen as well. The quartz movement does not deal very well with shocks, an experience experienced by field workers and manual workers such as technicians for example. It is in this context that the G-Shock was born.

G-Shock: an anti-shock system before being a range of watches
The specificity of G-Shock watches is above all the anti-shock system which allows the quartz movement to withstand violent shocks . To use an image, imagine that you drop a ceramic on a marble floor, both materials are renowned for their hardness but this hardness also involves a major disadvantage: if it does not deform, the ceramic can break.
The hardness of an object does not necessarily imply its resistance to all hazards and, where applicable, violent shocks. So in this case, how can a quartz watch survive a fall on a hard surface? The quartz movement being quite fragile compared to shock, Kikuo Ibe took up the concept of a rubber ball. In the middle of a flexible membrane, the movement inside the watch “floats” in a way in a protective cushion which absorbs shocks. This is the solution that allows G-Shocks to be renowned for their resistance.
But are durability and affordability everything in a watch? I think there are other parameters and design is one of them. Wearing a functional item is one thing, enjoying looking at it while using it is entirely different.
1. The feeling on the wrist
I'll tell you a secret: Benoît and David were surprised to see me arrive with a G-Shock on my wrist at the BonneGueule offices. It’s true that I had never worn one before to go to the editorial office. But what was going through my head?
Well quite simply I find that this G-Shock is different compared to those that I had seen and handled previously. When people told me about G-Shock, I had some apprehensions because it is a traditionally quite marked style
The GM2100 is the heir to another model which had previously caught my attention with its design: the GA-2100 and in particular the metal models, I saw the beginnings of a small stylistic break. But with the GM2100, I was seduced by its design. The latter certainly combines modernism – with G-Shock we are traditionally very far from the classic style watches that I like – but also a shape and color codes that appealed to me.
The shape of the bezel is octagonal. Other watches from the past have adopted this shape: some will systematically evoke the Royal Oak from Audermars Piguet in a completely different price range but the latter did not have a monopoly on this shape either. A Zenith model from the very early 1970s – nicknamed the Bolt – adopted not a bezel but an octagonal-shaped case. That being said, I like the shape of the GM2100, it gives the impression of solidity specific to the G-Shock and it has a particular twist.
How can you not notice this red dial first of all? The dial catches the eye all the more as it stands out compared to the rest of the watch: the case is made of steel – reinforced with carbon fiber which also brings lightness to the whole – with a coating Black PVD which gives it a more sober touch .
And besides, if we look at the dial, we can see another specificity: an analog AND digital display . So other watches obviously offer it like the Breitling Emergency or Aerospace
All the elements of the dial are also the same shade of red, like the hands but the latter receive an application of Neobrite
The glass is mineral and flat and, for this price range, that doesn't surprise me. G-Shock offers sapphire crystals on their premium ranges and the prices are higher than that of the GM2100.
2. Good dimensions, good sealing, great lightness
The GM2100 is not a professional model per se, I would say it combines lifestyle elements with some professional features, but with 200 meters of water resistance you can obviously swim and dive in complete peace of mind without any problems. make a professional diving instrument
The dimensions of the G-Shock are generous on paper: with 44.4mm in diameter, I can see the comments coming saying "it's way too big for my wrist": but be careful, the lugs are very very short and the The size of the bezel in relation to the dial gives a different impression when worn compared to other watches with a diameter of 44mm.
The watch is also not small on the wrist, but compared to my wrist of 17-17.5mm, the watch does not stick out. So unless you have a wrist below 16mm, I don't think this is a problem. The G-Shock style tends more towards a little oversized
As always, I would advise you to try it in a store and I would particularly recommend the store at 5 Rue Sainte-Croix de la Bretonnerie in Paris, which has staff who are passionate about the brand and very competent, particularly at the technical level, and this would allow you to familiarize yourself with the (very) different G-Shock models.
Despite these dimensions, the watch is not excessively thick with 11.8mm thickness and above all it remains very light with a weight of 75g. As said previously, the fact that it combines carbon fiber below the metal part makes it possible to significantly reduce the weight of the watch compared to a completely metal model.
Apart from the GM2100 but in 40.4mm
As I did for the Rado Captain Cook in the selection of divers for the summer , by mentioning another model with a smaller diameter during a review, in the case where the 44.4mm red model of the GM2100 definitely does not suit your wrist, I asked the brand to also provide – for comparison – the 40.4mm model. It is not available with a red dial like its big sister but in black
As we see in the photo, this model is, in my opinion, much smaller compared to the red model. There are some slight differences at the dial at 9 o'clock but for the most part, this watch has the same features except in a smaller format.
Compared to my wrist, although I find it more sober, I still prefer the 44.4mm red model: a question of presence but also for the twist with a more daring color. I also notice a difference between the two models in terms of the bracelet: although both are made of resin, that of the 40.4mm model seems a little more flexible to me compared to that of the “large” model. I nevertheless present it as an option for those who on trial would prefer this smaller diameter.
3. A watch with many features
For those who have already had a G-Shock, they will be on familiar ground. The GM2100 is no exception and offers many features including:
- A 24-hour stopwatch with precision to the hundredth of a second: classic function and used on my side for certain training sessions
- A countdown that you can program in advance if, for example, you need an audible notification to remind you of an important element of your schedule.
- Possibility of programming 5 daily alarms if your schedule for the day is timed or if you need several alarms to get up in the morning
- The calendar and automatic time: obviously, unlike a mechanical watch which needs to be set manually
, simply follow the user manual to be able to program your watch so that it automatically sets to the correct date and time in the time zone of your choice. As such, there is a world time feature to display the time with 29 different time zones corresponding to 29 major cities.
If there are in fact traditionally 24 time zones, there are also countries which have adopted particular time zones such as India (UTC + 4:30 a.m.) or Nepal (UTC + 5:45 a.m.). For the history of GMT/UTC I recommend reading the article on a GMT watch .
4. And the bracelet? The choice of resin
I am not used to wearing resin bracelets for a long time. Also, I wondered what I would feel with a bracelet like this on my wrist for 2 weeks. I am rather positively surprised by that of the GM2100. It is less flexible than a rubber strap but it is not excessively rigid either.
Resin bracelets
This is a type of bracelet that I did not include in the article on technical bracelets
In the case of the G-Shock, it is a polymer of synthetic origin. The term resin covers a very broad spectrum, it should be remembered that this generic term is often used by brands to designate a plastic material which can have a more negative connotation among customers.
Ultimately, in terms of technical bracelets, I personally prefer sailcloth and similar bracelets, rubber or nylon (premium type) but the G-Shock bracelet is not unpleasant on the wrist either. It is functional and sober, nothing more.
I like to twist watches with their straps and now I'm a little sad because I can't really do it with the GM2100 : it's not a problem to change the strap because G-Shock recently included easy quick releases to remove to change bracelet. The difficulty comes from the fact that you only need straps from the brand to adapt them to the watch
Another point, unfortunately, the G-Shock online store does not offer in its offer to sell its bracelets separately. There are different bracelets from G-Shock: rubber bracelets, some also made of textile or even metal but, unfortunately, you have to buy the bracelet with the corresponding model and then make the switch.
Also, I would like to recommend that the brand offer its bracelets for sale one day for its customers. The importance of the bracelet has only grown in recent years, customers are no longer satisfied with the original bracelets but want to personalize their tocantes. This observation is valid for a watch costing several thousand or tens of thousands of euros but also for a watch costing a few hundred euros.
We nevertheless remain on a product offered at a very affordable price so I do not expect to automatically have premium bracelets, there are other ranges from G-Shock for that. On the other hand, there is one element on which I will be even more uncompromising: I will actually test the resistance of the watch to see what it has in its stomach.
Time for the real test: to the end of our limits
After describing the features of the GM2100 Red, it's time to take it to the next level. Instead of just doing a traditional review, we might as well take G-Shock at its word on the effectiveness of their anti-shock system and actually put it through a test with real and numerous violent shocks over a period of 15 days. And that's good, I have a special test to give him. And for that you have to confide something personal.
1. HIIT, Cross Training, Combat and Tabata
I am a fan of intensive training: between five and six training sessions per week, including three HIIT type training sessions.
Tabata is actually a variation of HIIT from Japan: it involves performing 20 seconds of intensive exercises such as burpees, push-ups, jump squats or plyo lunges.
Then, simply add the number of Tabata that you are able to handle: generally the workouts last between 20 and 30 minutes in total. A little less as a beginner, more for veterans. To be even more precise, I practice Tabata including Combat by mixing – according to the coach's instructions – speed jabs, kicks or free fight facing the bag
Traditionally, Tabata is done in 20 seconds - 10 seconds but many variations are available and it is possible to do 30-10, 50-10 or even completely eliminate the recovery time.
Learning to overcome your limits is excellent. Being methodical and progressive in this type of training is an imperative so I would like to salute the three coaches who follow me: Fred but also (the very wise) Philippe and Jeanna, great professional athletes, graduates and great specialists in their fields.
So yes, the G-Shock GM2100 will undergo these intensive training sessions at the same time as my body, i.e. six Tabata Combat training sessions in two weeks, not to mention six other training sessions which nevertheless include running, TRX, some bodybuilding and technical exercises. for the fight. The goal is obviously to test the watch's ability to withstand repeated, rapid and violent shocks.
2. Two weeks of training later: the verdict
So, has the GM2100, which is not a model designed specifically for sports, survived?
The watch accompanied me without any problem during my intensive training sessions. Despite the number of shocks and rapid and violent sequences of exercises, the watch had no damage, the time keeping is impeccable, all the watch's functionalities are operational.
Although not a sport type, this GM2100 remains a G-Shock and it holds up perfectly in all the situations it has encountered. It's a watch that surprised me because I clearly observe G-Shock's desire to develop its ranges outside the traditional sphere of sports or professional watches to arrive at a balanced watch by mixing lifestyle and technicality.
Without pretending to discover the G-Shock for the first time, I am pleasantly surprised by this model which amazes me with its mixture of modernism and versatility in terms of its use. And for a very contained budget.
Style-wise, I see several options for this watch. Like adopting the codes of street culture in the choice of your outfit, but for my part I will not hesitate to do twists and everything goes: workwear, a workwear mix like work jacket combined with a tie and a shirt more classic too. Of course, I don't think the watch is suitable for a totally formal outfit but apart from that, for sports, for running or having a drink with friends, this red G-Shock puts its dose of originality in an outfit with its red dial. And at a very modest price.
See you soon for the next test, I’ll run back to my training 😉
WE love :
- A large diameter on paper but – frankly – by integrating all the parameters (opening of the dial, real dimension of the case by integrating the lugs), the watch turns out to be suitable for a wrist of 17-17.5mm. Another illustration of the difference between the real feeling when wearing and the diameter of the watch on paper
- Originality of this red dial that I really like: a red that is not at all aggressive and yet gives a twist to the watch
- The metal case is surprisingly light because it mixes carbon fiber: the watch turns out to be light (72g) , aided by a resin strap
- A very lifestyle watch with this versatility, being able to use it both for going out and for intensive training - if you like a style that is still quite modern in terms of the design of the watch
- The mix of digital and analog display for reading the time
- Other dial colors are available: navy blue, steel and green
We like less:
- The Neobrite luminescent material appears, in my opinion, to be a bit weak over time.
- One regret regarding the bracelets: the brand does not offer other bracelets to purchase separately to further personalize your G-Shock by adopting other bracelets than the one supplied with the model purchased.
