Casio: the cult watch turned collector's phenomenon

Step into the world of Casio, the Japanese brand that turned the digital watch into a true cultural object. From the legendary G-Shock to limited editions in collaboration with Stranger Things, Evangelion or Back to the Future, Casio has grown far beyond watchmaking: it is now a cornerstone of streetwear and global pop culture. At MTHOR, we curate the most sought-after Casio references of the moment — iconic models, sold-out collabs and anniversary editions — all authenticated by our team of experts before shipping. Whether you are a passionate collector or looking for your first G-Shock, our Casio collection brings together the best of the brand with the three legendary letters.

The story of an icon: from the calculator to the G-Shock

Founded in 1946 in Tokyo by Tadao Kashio, Casio first made its name with calculators before revolutionising watchmaking in 1974 with the Casiotron, the first fully digital watch with an automatic calendar. But the real legend was written in 1983: engineer Kikuo Ibe, after breaking the watch his father gave him, set himself a crazy challenge — to create an unbreakable watch. After more than 200 prototypes, the G-Shock DW-5000C was born, built around the "Triple 10" concept: survive a 10-metre drop, withstand 10-bar pressure and offer a 10-year battery life. A watch designed to survive anything.

Since then, the G-Shock has won over skaters, soldiers, hip-hop artists and fashion lovers around the world. Worn in music videos, on runways and on the wrists of the biggest celebrities, Casio now multiplies event collaborations — Stranger Things, Evangelion, Back to the Future — that sell out within hours and reach impressive resale values.

Unique toughness: how does G-Shock protection work?

The secret of the G-Shock lies in its revolutionary shock-resistant structure: the timekeeping module is suspended inside a hollow case and protected by absorbing materials, so no impact reaches the mechanism directly. The oversized resin bezel protects the glass, while the buttons and strap are designed to absorb impacts. On recent models like the GA-2100, Casio uses the Carbon Core Guard structure: a carbon fibre-reinforced case that is thinner, lighter and even more resistant.

The result: bulletproof durability that built the brand's worldwide reputation, water resistance up to 20 bar on most G-Shocks, and remarkable everyday comfort despite the bold look. This absolute reliability is why a G-Shock is often passed down from generation to generation.

The iconic models in the collection

Our Casio collection brings together the references collectors love most. The G-Shock GA-2100, nicknamed the "CasiOak" for its octagonal bezel reminiscent of the greatest luxury watches, has become a global best-seller — available in off-white GA-2100-7A7, red GA-2100-4A, all-black GA2100-1A1 or Virtual Blue GA-2100VB. On the collaboration side, the G-Shock x Stranger Things DW-5600STT and the Casio Vintage x Stranger Things AQ-800EST plunge the cult watch into the world of Hawkins, while the G-Shock Evangelion GA-110EVA30 celebrates 30 years of the cult anime. Nostalgics will fall for the Casio Back to the Future CA-500WEBF, a nod to Marty McFly's calculator watch. Finally, the most coveted piece of the moment: the Ring Watch CRW-001, a ring watch launched for the 50th anniversary of Casio watchmaking, sold out worldwide within minutes and available at MTHOR in black and gold versions. Not forgetting the Baby-G Playful Hearts series and the vintage MTP and AQ classics that complete the collection.
