4D Concrete Automatic Sport Watch
New colours now available.

The world of watches swept by a frenzy of colours, here we are! Introducing seven colours in one go, we know how hard it must be to choose one.

A sport watch playing with the looks.

Coloured concrete、 316L solid stainless steel watch strap, plus crown guards、3D hands and other design details. An athletic pedigree full of masculinity, audacious and passionate; it is charismatic, attractive and surprisingly easy to match with any styles.

A challenge in concrete colouring skills.

The coloured dial is made piece by piece with hand-poured and toned concrete。After mixing in the pigment, fluidity of the concrete decreases, making the pouring process more difficult, hence testing the skills of our workshop’s craftsman. Apart from that, cement is naturally grey in colour, there’s usually a difference in colour after it solidifies, countless trials must be done back and forth in order to achieve the colour designated by the designer.

Hand-cured concrete dial.

22STUDIO developed its own formula of concrete, which can quickly solidify and form, with low shrinkage and high strength. Moreover, after each dial mold has been manually filled with concrete, it will go through 14 days of curing in the cellar. Similar to aging beef or red wine, this process can maximize the structural strength of concrete, as well as producing a uniquely natural texture on the surface.

Exclusive to the automatic watches: stainless steel link strap.

For the first time, 4D series is paired with stainless steel link strap solely designed for 22STUDIO’s automatic watches, made of 316L stainless steel, and butterfly buckle design. Link strap has several advantages; just put it on without hassle after length adjustment, it is durable, resilient and corrosion-resistant. Although the overall feel is heavier, however, it can help the weight of the whole watch more evenly distributed on the wrist.

Horn-shaped crown guard

We made a notch by CNC process around the original crown, screwed in the horn-shaped crown guard, therefore creating a protective barrier. This design can reduce the initial impact by an extreme collision and prolong the service life of the watch, providing you with peace of mind when engaging in physical activities. The details of craftsmanship also enhance the overall appearance with sporting spirit and mechanical aesthetic.

Super-LumiNova three-dimensional hour marker

The luminous feature: Super-LumiNova®, a product of the Swiss manufacturer LumiNova AG Switzerland. Excellent chemical stability, a green luminous of high brightness, no matter how dark the environment is, the time can be checked quickly and precisely. Three-dimensional hour markers are made by metal CNC process, each topped with pigments of Super-LumiNova. The tiny hour marker is only 3.9x1x0.8mm, which must be precisely mounted on the concrete dial; an extreme challenge of demolding and alignment skills.

Stable and durable Swiss automatic movement

We use Swiss Sellita SW200-1 automatic winding movement SW200-1: vibrations per hour 28’ 800bph, maximum power reserve is 38 hours, accuracy of +/- 20 sec/day, standard three hands of hour, minute and second, date display.

NEW “Screw-in” case design

The bezel and case have been assembled by our new 「screw-in design」, four screws hidden in the groove of the strap screw-in upwards to lock in the bezel. The innovative structure eliminated the old maintenance opening at the 12 o’clock position, improved its performance in water resistance, and simplified the disassembling and repair process when necessary.

Sapphire crystal glass

22STUDIO uses sapphire crystal glass for all of our wristwatch series. The hardness of sapphire crystal glass is second only to the hardness of diamonds, with a Mohs hardness of 9. With high degree of hardness, it’s less likely to leave scratching marks. Optical permeability helps time reading fast and easy, along with other advantages such as low friction and high temperature resistance.
