The must-have Macro Loupe for all watch lovers

I am an absolute fan of my watch which was only made in one copy by Tissot in 67 for the designer of the logo of the universal exhibition in Montreal in 1967 Julien Hébert. This dial Terre des Hommes makes this watch unique without brand without date no other information than this magnificent logo going around and these sublime black and gold indexes

World Expo 1967

To be honest, it's difficult to give my opinion because I just bought this watch because I'm going on holiday to Asia with my son and I chose this model for its design, the Bluetooth and the GMT and above all their proven solidity because yes I took 2, one for me and my son, I will give a more detailed opinion when I get back

Watch that I have been a fan of since its acquisition, a diver in the 80s, what can I say, everything suits it, nato leather steel can be worn in all circumstances with its ideal diameter 38.5mm, a thickness of 13mm and its 20atm, readability at all times with its Arabic numerals and incredible luminescence for its age, a granny who could give lessons to many young divers

G-Shock is a Casio watch line born in 1983 in Japan, conceived by engineer Kikuo Ibe with a radical brief: to build a virtually indestructible digital watch for real-world use &mdash; from daily life to extreme environments &mdash; and to express a utilitarian aesthetic language of bold geometry, resin or metal cases, and digital/analog readouts that has become a global reference for athletes, field professionals, and street culture.
<h3>1983 origins: Kikuo Ibe, the &ldquo;Triple 10&rdquo; rule and the first G-Shock DW-5000C</h3>
In the early 1980s, Casio&rsquo;s &ldquo;Project Team Tough&rdquo; codified a durability philosophy called &ldquo;Triple 10&rdquo;: 10-year battery life, 10-bar water resistance, and shock resistance to a 10-meter drop; in 1983, the G-Shock DW-5000C debuted with a floating module in a cushioned structure and an octagonal case that would define the &ldquo;Origin&rdquo; (5000/5600 line). &ldquo;Triple 10&rdquo; was not a slogan but a design specification: internal damping, controlled thickness, protected pushers, robust steel backs, and bands engineered to endure torsion and vibration; that foundation enabled decades of added functions (radio time, solar, Bluetooth), new architectures (carbon-reinforced resin, steel, titanium), and a visual vocabulary instantly recognizable worldwide &mdash; which is why the Triple 10 still underpins G-Shock&rsquo;s clarity and durability today.
<h3>&ldquo;Master of G&rdquo;: G-Shock Frogman, G-Shock Mudman, G-Shock Rangeman, G-Shock Gravitymaster, G-Shock Gulfmaster</h3>
&ldquo;Master of G&rdquo; labels specialist G-Shocks for sea, mud, air, or all-terrain duty: the G-Shock Frogman (1993) brought ISO 6425 &ldquo;Diver&rsquo;s 200 m&rdquo; certification into the lineup; the G-Shock Mudman adds dust/mud resistance for rally and backcountry use; the G-Shock Rangeman (GW-9400) packs triple sensors (altimeter/barometer, compass, thermometer); and G-Shock Gravitymaster and G-Shock Gulfmaster target aviation and marine environments with tailored sensor/display sets. The point is not box-ticking but fulfilling a mission &mdash; diving, desert, cockpit, deck &mdash; via instrument-grade specs, yielding functional, sometimes asymmetric, forms and glove-friendly ergonomics; in short, Master of G prioritizes job-ready information over ornament from the outset.
<ul>
<li>G-Shock Frogman &mdash; ISO Diver&rsquo;s 200 m, asymmetric architecture, modern analog variants (e.g., GWF-A1000); professional tool.</li>
<li>G-Shock Mudman &mdash; Mud/dust sealing, stout cases, oversized pushers; rally/outdoor focus.</li>
<li>G-Shock Rangeman &mdash; Triple Sensor (direction/pressure/temperature), log functions; all-terrain.</li>
<li>G-Shock Gravitymaster &mdash; Aviation displays/materials, high-contrast indexes; cockpit legibility.</li>
<li>G-Shock Gulfmaster &mdash; Marine readouts (tide/pressure), combined displays for coastal navigation.</li>
</ul>
<h3>Core technologies: Carbon Core Guard, Tough Solar, Multiband 6 and Bluetooth</h3>
Modern G-Shocks leverage a &ldquo;Carbon Core Guard&rdquo; chassis &mdash; a carbon-fiber-reinforced resin case that stiffens and lightens the structure, improves module protection, and enables slimmer profiles (notably in the 2100 series); &ldquo;Tough Solar&rdquo; recharges an accumulator from ambient light; &ldquo;Multiband 6&rdquo; auto-corrects time via radio signals from six global transmitters; and Bluetooth links the watch to a smartphone for auto timekeeping, settings, and convenience features. The common aim isn&rsquo;t gadgetry but reliable time and service day in, day out &mdash; which is why the carbon + solar + radio/Bluetooth combo seeks more autonomy, accuracy, and ease of ownership.
<h3>Iconic lines and best-sellers: 5000/5600 &ldquo;Origin,&rdquo; 2100 &ldquo;CasiOak,&rdquo; Full Metal, G-Steel, MT-G &amp; MR-G</h3>
The 5000/5600 family carries the rectangular original; the 2100 &mdash; nicknamed &ldquo;CasiOak&rdquo; &mdash; recasts that DNA into a minimalist octagonal analog-digital format that wears slim and easy; &ldquo;Full Metal&rdquo; (e.g., GMW-B5000) reimagines the Origin in all-metal, G-Steel mixes metal and resin for dressier heft, and MT-G (metal-twisted) and MR-G top the range (steel/titanium, advanced finishing, MR-G built on Yamagata&rsquo;s Premium Production Line). Beyond materials, these families map neatly to use-cases and budgets while preserving legibility, toughness, and G-Shock codes &mdash; hence why the GA-2100/GA-B2100 &ldquo;CasiOak&rdquo; crystallized a thin, featherweight, universal G-Shock without losing the signature.
<ul>
<li>G-Shock DW-5600 &mdash; Direct heir to DW-5000C; rectangular &ldquo;Origin,&rdquo; ultra-legible and compact.</li>
<li>G-Shock GA-2100 / G-Shock GA-B2100 &mdash; Octagonal &ldquo;CasiOak,&rdquo; Carbon Core Guard; Bluetooth/solar options.</li>
<li>G-Shock GMW-B5000 &mdash; Full-metal Origin; steel or titanium, radio/Bluetooth/solar.</li>
<li>G-Shock G-Steel &mdash; Metal/resin hybrid with a dressier vibe; steel or resin straps.</li>
<li>G-Shock MT-G &mdash; Metal-Twisted; advanced Core Guard structures, Bluetooth/Multiband 6.</li>
<li>G-Shock MR-G &mdash; Titanium flagship, hard coatings, Japanese artisanal finishing.</li>
</ul>
<h3>Positioning, pricing and channels: from entry to Japan-made premium</h3>
The price spectrum runs wide: &ldquo;Origin&rdquo; and select 2100s target accessibility; &ldquo;Master of G&rdquo; steps up with sensors and purpose-built cases; then MT-G and especially MR-G assume fully premium roles (steel/titanium, hard coatings, elevated assembly, Yamagata workshops). Global distribution blends <a href="https://www.dialicious.com/en/casio">Casio</a> e-commerce with retail partners, and limited editions roll out regionally; more than &ldquo;positioning,&rdquo; it&rsquo;s the mission logic that guides selection (city, sea, aviation, outdoors) in a clearly structured catalog &mdash; so the matrix lets you choose function/aesthetic first, then material/finishing tier.
<h3>Collaborations, pop culture and communities: NASA, BAPE, KITH and the street</h3>
G-Shock&rsquo;s cultural reach owes much to collaborations (NASA, BAPE, streetwear collectives, influential retailers) and its adoption by hip-hop and skate scenes since the 1990s&ndash;2000s; the G-Shock DW-5600 NASA (2020) popularized an all-white &ldquo;worm&rdquo; logo look, while repeated BAPE tie-ups and projects with outlets like KITH keep community ties fresh; these sit alongside anniversary pieces (40th) and the product&rsquo;s inherent &ldquo;urban utility&rdquo; (toughness/value/style), yielding rare longevity and less volatile trend cycles &mdash; in effect, the watch became a cultural signal as well as a tool, without ceasing to be an instrument first.
<h3>Buying guide: use, size, power and functions to pick the right G-Shock</h3>
Start with mission (minimalist daily, sea sports, hiking, cockpit), then size/thickness (compact rectangular Origin vs bolder Master of G), then power and accuracy (battery vs solar, radio/Bluetooth). Slim wrists gravitate to 5600/5000 or 2100; &ldquo;instrument&rdquo; needs point to Master of G; metal preference suggests Full Metal/G-Steel/MT-G/MR-G. Best practice: check legibility, strap comfort and local service options; remember that the right G-Shock is the one that serves your use and constraints first, not the longest spec sheet.
<h3>Conclusion</h3>
Four decades on, G-Shock remains a tool benchmark: cushioned architecture, clear displays, autonomous accuracy, and clearly tiered families from discreet daily (5600/2100) to specialized environments (Master of G) up to luxury (MT-G/MR-G). If you want an &ldquo;iconic first,&rdquo; the 5600/5000 Origin is the obvious start; for a contemporary, ultra-wearable shape, pick the 2100; for hard duty, look to Frogman, Mudman or Rangeman; and for metal and finishing, MT-G/MR-G clarify the premium step.

Casio g-shock GA-B2100, solar, connected (gadget for me...) light (carbon insert) and a really reasonable size. Very readable, waterproof to 200m, etc...etc... I've had it for a month, but with the little experience I have of this brand I'm almost certain that I won't be disappointed. A very good purchase.

Nice surprise

I just bought it in January 2025 so it's going to be complicated to give you a concrete opinion.
I had never had a G-Shock before and thinking about it I found it surprising and a shame especially when you've been collecting watches for 25 years now. So it was time to get the famous CasiOak for my part the bluetooth and solar version model GA-B2100-1AER.
Having been used to wearing GARMIN SmartWatches since 2015, the all-plastic and connected type didn't surprise me but where G-shock makes the difference is to think that for relatively low prices you can have a watch with such impressive specifications and a robustness to all tests.
This GA-B2100-1AER is really cool and comfortable to wear because it is very light, the octagonal shape gives it a slightly seventies look that I like, the sunray dial is very effective and the layout of the opening on the digital screen is harmonious.
Apart from the push buttons that I find much too short for proper use, otherwise it is flawless.
Now that I have fallen into it, I have made a small list of the next G-SHOCK acquisitions, I was weak and quickly fell for the DW5900-1 which appeared in 1998 in the cult film The Big Lebowski (my favorite), and on Walter's wrist who wears the famous DW-5900C-1 that I will receive soon, opinion to follow...


My first G-shock but not the last

This G-Shock, known and recognized for its shape, is particularly comfortable and practical. With its features, its pleasant buttons and its readability it is perfect for the work of sports educator. It works with solar energy, which is appreciable. The yellow color is warm and close to gold. The contrast with the black writing is very pretty.
