If you can collect only one 4D Concrete Watch, look no further; this is the one!
A fusion of sports function and the spirit of adventure, this is the ultimate representative of four-dimensional wrist watch series.
Hyper evolution of sports function
The luminous function of [Explorer] has been upgraded by Super-LumiNova®, a product of Swiss manufacturer LumiNova AG Switzerland. Its resistance to light is very strong, along with excellent chemical stability, the green luminous of high-brightness can quickly give a precise reading of the time in any dark environment.
Furthermore, the horn-shaped crown guard has been designed for the first time to protect the crown and reduce the impact caused by harsh contacts. When engaging in greater physical activities, you can wear the watch with peace of mind.
Fearless explorations in the metropolis
In 19th century, tools made of leather and brass initiated the great industrial era, enabling people to build factories and cities. Although the appearance of these materials will change over time; however, they are capable of passing various challenges with their strong resilience.
【Explorer】We have chosen the nostalgic brass case and leather strap to be parts of the 4D automatic watches, reproducing the fearless spirit of a century-old urban explorer.
NEW Super-LumiNova hour marker
For the first time, three-dimensional hour markers are added 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. On the spiral-staircase shaped concrete dial, luminous hour markers on different levels can be seen in the dark, elegantly playful and captivating.
NEW Horn-shaped crown guard
Based on our repairing experiences, if the watch accidentally falls and happens to land on the crown, it’s likely to tilt or even break. This counts for about 7% of our maintenance service; therefore, to make concrete watches more suitable for adventures, strengthening the crown protection is our top priority. This time in【Explorer】we created a notch by CNC process around the original crown，screwed in the newly designed horn-shaped guard, increasing its resistance to impact. The details of craftsmanship also enhance the overall appearance with mechanical aesthetic.
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.
Cured concrete dial by hand
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 be placed in 『concrete curing room』for 14 days with constant temperature and humidity. 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.
Date window in a sturdy well
In the simple and neat spiral staircase design, a sturdy well has been added in the three o’clock spot. In addition to reading the date, you can also see part of the movement structure.
Super-LumiNova three-dimensional hands
In order to synchronize with the dial of three-dimensional spiral staircase, we designed the one and only three-dimensional watch hand in the world. It breaks away from the traditional two-dimensional concept of watch design, entering the real three-dimensional space, or even to the fourth.
Traces of time in brass case
After a long period of use, brass is known to change the color, producing different shades or partial misty patterns due to oxidation. 【Explorer】 Marks of use appear in the brass case and faucet as time passes; at 22STUDIO, we believe it is the most beautiful state of the watch.
When delivered, the brass is brand new and unoxidized.
Sapphire crystal glass and case-back
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.
