4D Concrete Automatic Duo: Stand FirmBetween Extremes

Streamlined Evolution × Engineered Rebirth × TheNew 4th Dimension
At a certain stage, you realize that internal conflicts don't always demand a victor. You can pursue your ambition while knowing exactly when to step back—standing solid between the two.

This restructures the weight of time. For us, this isn't just a design evolution; it is about engineering a solid anchor point for your daily life.

Duo: New Structure. A New Level of Presence

If the original 4th Dimension Spiral
Staircase symbolized a "breathing space" for the busy urbanite, the all-new Duo confronts a more fundamental challenge: Balance.

Modern life often oscillates between extremes—outer versus inner, career versus family, reason versus emotion. The Duo focuses on that precise moment of stability amidst the movement.

True balance requires no sacrifice. It is not about choosing one over the other, but about attaining both.

The Dual Spiral: A New Equilibrium

With Stoic concrete, we constructed two corresponding spiral staircases. This is more than a structural addition—it is the philosophy of the "Duo."

These stairs embody forces that seem opposite, yet coexist. They spiral elegantly, never intersecting, yet perfectly aligned in the same space. Neither dominates the other. Instead, they achieve a state of ultimate geometric stability.

The raw texture and weight of the concrete lend the watch a quiet confidence. As the hands flow between the stairs, you realize that true calm doesn't come from escaping the chaos, but from inner order.

The Duo speaks to this truth: No matter how extreme the outside world becomes, holding this balance allows you to forge a solid self within the flow of time.

Our Most Significant Evolution. A New Erafor the Concrete Watch

To integrate the mechanical watch seamlessly into daily life, we redesigned the 4th Dimension from the inside out. The case diameter is streamlined from 45mm to 43mm, and the body thickness reduced from 14.5mm to 12.5mm*. This retains the signature spatial depth of the
series while significantly upgrading wearing comfort.

Gaze at the new watch, and you see a piece of Brutalist architecture standing on your wrist. Concrete, stainless steel, bronze, and leather—diverse materials presented in their raw, honest form.

The newly added Box-shaped Sapphire Crystal enriches the play of light and shadow, adding a layer of harmonious, retro charm. We offer three distinct colorways, tailored for three different types of urban travelers.

(Note: Total thickness including the crystal is 14.5mm.)

4D Concrete Automatic DUO: Specifications

High-End Japanese Miyota 9015 Automatic Movement

To achieve a sleeker overall design, we utilized the high-end Miyota 9015 movement. It is 0.7mm thinner than our previous movements (reduced from 4.6mm to 3.9mm), and highly regarded in the industry for its stability and precision, offering a power reserve of approximately 42 hours.

For this edition, we have also customized a 22STUDIO exclusive rotor, further elevating the mechanical aesthetic.

Hand-Castin house: Exclusive Sustainable Concrete Dials

Fair-faced concrete is the ultimate expression of cement craftsmanship. To achieve that raw, mesmerizing texture, we rely on precise molds and expert execution. Every 22STUDIO dial is hand-cast at our HQ in Taipei.

The Dual-Dial design demanded a new level of precision. With a strict 0.15mm tolerance, combined with the varying shrinkage rates of colored concrete, bonding the two layers was a massive
technical hurdle.

For us, "a new product always comes with a new challenge." This mindset
is in our DNA. We simply step up and meet the challenge.

Box-shaped Sapphire Crystal 

All 22STUDIO watches feature sapphire crystal, a material second only to diamond in hardness and highly resistant to scratches, ensuring the watch maintains its clarity and beauty over time.

For this model, we specially selected a dual-domed, box-shaped sapphire crystal, which allows the case to be further slimmed down. At the same time, the refraction and reflection produced by its geometry add a dynamic depth to the watch from every angle, dramatically transforming the overall character of it — a detail we found ourselves completely enamored with.

Super-LumiNova® Luminous Hands and Three-Dimensional Hour Markers

All 22STUDIO timepieces feature Swiss-made Super-LumiNova® from LumiNova AG Switzerland, known for its exceptional chemical stability and high luminosity, ensuring clear readability even in the darkest environments.

The watch employs CNC-machined metal hour markers infused with Super-LumiNova®. Measuring just 3.9 × 1 × 0.8mm, these miniature markers must be precisely embedded into the concrete dial, a process that demands extreme precision in both mold release and alignment.

Well-Shaped Date Window with Inset Magnifier

Another 22STUDIO original design. We utilized the interior space created by the spiral staircase dial to design a "well-shaped" date window. Instead of bonding the date magnifier to the top glass, we installed it at the upper edge of the "well." This provides a clear date display while adding a rich, playful visual layer to the dial.

Crown Guard Design

The crown guard design features a CNC-machined recess around the crown, secured with a guard bridge to create a protective barrier. This reduces the risk of direct impact to the crown, extending the watch's lifespan and providing peace of mind during vigorous activities. This craftsmanship detail also infuses the design with a sporty soul and mechanical beauty.

Proprietary Strap Curvature Fixer

A signature 22STUDIO innovation, the Curvature Fixer is designed to help
the leather strap maintain a natural oval shape—one that more closely follows
the wrist’s cross-section. We discovered that this geometry is key to wearing
comfort. By holding the strap and watch case in a more balanced position, it creates a fit that feels more stable, refined, and comfortable throughout the day.

4D Concrete Automatic DUO Collection

Mist Grey — Minimalist Monochrome

Our most iconic colorway, expressing the purest concrete character of 22STUDIO, is now paired with an automatic watch for the first time. It features a high-density fair-faced concrete dial in layered shades of grey, a sandblasted matte stainless steel case, matte grey hands, C3 green Super-LumiNova®, and a grey embossed leather strap.

Ice & Fire — Order in Contrast

A red-and-blue fair-faced concrete dial meets a faceted polished stainless steel case, with glossy silver-tone hands and indexes that catch the light from every angle. The result is a modern expression of precision and clarity, bold yet composed. Paired with a carbon-black recycled cotton strap, it also carries the idea of circular reuse, bringing a minimalist and fashion-forward design language into perfect balance.

Bronze Explorer — An Urban Spirit of Adventure

A beige and stone-grey fair-faced concrete dial is paired with a brushed bronze case, black hands and indexes, vintage orange Super-LumiNova, and a brown vegetable-tanned leather strap, creating a strong safari-inspired character. One of bronze’s most distinctive qualities is that, over time, it naturally oxidizes and changes color, developing tonal variation and subtle cloudy patina marks across the surface. To 22STUDIO, these traces shaped by time are when a watch becomes most beautiful.

Bronze ships in a new, unoxidized rose-gold tone.

Sustainable Packaging: Honest and Solid

In our commitment to environmental protection, 22STUDIO packaging is made almost entirely of paper, showcasing the raw character of the material. The outer sleeve is made of thick grey cardboard with half-cut folds. The inner layers consist of shock-absorbing recycled corrugated paper pulp. The watch is placed in an exclusive dust bag before being housed in the box.
