4D Concrete Watch Decade Anniversary Edition
The Fourth Dimension Commemorative Edition: Space-Time Spiral

Is time merely a human illusion? The mystery of whether the past, present, and future coexist simultaneously remains unsolved. The new design of the "Fourth Dimension Concrete Watch Commemorative Edition" is an inquiry into this concept.

With a base of rotating concrete stairs, each step represents an hour, completing the entire journey in twelve hours. Is it possible that by shrinking ourselves and stepping onto new smaller stairs, our pace quickens, allowing us to accelerate towards the future to realize our dreams? Looping back to the starting point, there's yet another miniature staircase rapidly descending, resembling a fold in space-time, allowing one to return to the past and alter history.

Freedom to traverse the past, present, and future remains a technological frontier yet to be realized. This wrist-mounted concrete maze, an architectural fantasy, breaks the linear constraints of the fourth dimension, brimming with boundless imagination and poetic science fiction.

Cyclical Design: Endless Three-Dimensional Space

Representing the "past, present, and future," the three staircases create new spatial divisions, visually cycling and repeating, evoking a sense of endless enchantment. It's as if defying natural laws, crafting intricate, transformative structures.

It brings to mind the optical illusions of M.C. Escher's art and the iconic Monument Valley mobile game featuring three-dimensional mazes.

Starting from zero, an outer ring adds an 11-step staircase, with each step representing 2 minutes, visually appearing faster. Similarly, starting from zero, an inner ring adds a 16-step staircase, with each step representing 2 minutes, visually moving counterclockwise. All three staircases extend downwards into the darkness at the bottom, emphasizing the light and shadow variations caused by the height differences of the stairs.

Looking back at the first generation, a decade of passion and youth.

The initial prototype made its debut at the Simple Life Original Festival in 2013, by combining ideas of "time" and "three-dimensional space," the original design concept of "Four Dimensions" was created. It accompanied us in various exhibitions and competitions, marking it as 22STUDIO's first of the wristwatch series.

Gradual accumulation along the path of development.

The product went through several years of exploration, having developed Automatic, Sector, Ups & Downs and Sports models. We always have a higher expectation for our products, with each series featuring new ideas and improvements. Now, after accumulating experiences along the way, it's time to pay tribute to the Four Dimensions Concrete Watch that has been with us for a decade.

To celebrate this milestone, we've specially invited designer Lin Liyu to design our 10th-anniversary commemorative edition. Lin Liyu, who previously worked at the LEGO headquarters in Denmark, now runs a paper sculpture brand and excels in three-dimensional space and sculpture.

Case diameter increased to 44mm, yet lighter and thinner.

The new version of the Four Dimensions watch has an increased case diameter of 44mm, making it visually more impactful. The thickness has been adjusted to be lighter and thinner, enhancing the comfort of wearing a large watch.

Concrete well-shaped date window, simple and solid.

A sturdy well-shaped window is installed at the three o'clock position on the dial, allowing for easy date check and adding a touch of mature stability to the aesthetic.

Swiss Super-LumiNova three-dimensional hands.

A product of the Swiss manufacturer LumiNova AG Switzerland, Super-LumiNova® offers excellent light resistance and outstanding chemical stability. With its high brightness green luminescence, no matter how dark the environment is, the time can be read precisely at once.

Hand-cured concrete dial.

Moulding with 22STUDIO's exclusive formula of concrete, the dial is cast and then manually refined after a 14-day curing process. This makes the cured concrete dial firmly structured and uniquely textured, and then finished with a size inspection as accurate as 0.2mm to ensure quality.

All-new innovative strap curvature fixer.

Striking the optimal balance between the weight of the concrete watch and wearing comfort has always been our priority. After numerous attempts, 22STUDIO has finally developed a "strap curvature fixer" specifically for our watches. This fixer creates a perfect oval shape when attaching the strap to the watch, significantly improving the wearing experience with better balance and comfort. It is first introduced in the Ten-Year Anniversary Upgraded Classic Edition of the Four Dimensions series.

Fluoro-rubber (Viton)Strap.

Featuring "fluoro-rubber" straps of the same grade as the sport bands used in Apple Watches, they provide excellent resistance to high temperatures, acids and alkalis, as well as shock absorption and durability. One of the biggest advantages of this strap is its weight, as it is relatively heavy, offering a solid and comfortable feeling when worn.
