Introduce Architecture, a New Model Inspired by Metabolism

Introducing Architecture, TACS’ latest design in the world of wristwatches inspired by the historic Nakagin Capsule Tower in Tokyo, Japan.

Japanese Metabolism

The Metabolism Movement in architecture is an avant-garde design approach that emerged in the 1960s in post-war Japan, focusing on the integration of organic and biological principles into the architectural design as a response to the rapid urbanization and economic growth that the country was experiencing. The architectures as a result are dynamic and could potentially evolve and transform over time, reflecting the changing needs of society and its inhabitants. The Nakagin Capsule Tower designed by famed architect Kisho Kurokawa is one of the most iconic buildings that emerged from the movement.

Unexpected Materials

Crafted from new materials from our other models, Architecture features an open-heart dial made from concrete, echoing the architectural inspiration behind it. The 41mm case is crafted from 316L stainless steel, a type of surgical-grade steel that is well-known for its robustness, wearability and durability. Architecture, much like its inspiration, is a timepiece that is built to last for years to come.

Open-heart with Clutch Wheel Exhibit

The open-heart details, reflecting the modular design of the Capsule Tower, are located between 6-7 o'clock and 3 o’clock on the dial, giving a glimpse of the intricate mechanism and clutch wheel at work while adjusting time with the 7mm push/pull crown. The transparent case back, made from K1 glass allows you to see through the watch’s inner workings without compromising its functionality. Staying true to our Japanese roots, Architecture is powered by a Miyota movement and crafted entirely in Japan.

Made in Japan

Architecture is crafted in Nagano (信州) and inspected onsite to ensure premium fit and finish in a region famed for its precision.

All-day Wearability

Architecture is the ultimate timepiece for those who demand style with wearability and durability. The hypoallergenic nature of 316L stainless steel makes it ideal for those with sensitive skin, as it provides all-day wear without any risk of irritation. This material is also more resistant to corrosion, meaning the watch will retain its shine and lustre even after long wear, while the colourfast nature makes it incredibly easy to clean. Simply wipe the watch with a cloth and it will look as good as new. The lens and case back, both crafted from K1 glass with water-resistant up to 10ATM, provide strong protection from everyday activities. In the dark, Super-LumiNova on the essential components ensures you can tell time with ease.

With its robust construction, anti-allergenic properties, and intricate design, Architecture will be a reliable companion for years to come.
