Inspired by the iconic vintage twins lens reflex camera

First released in the late 1920s, twin-lens cameras were widely used by photojournalists and correspondents to document World War II in Europe thanks to its robust and periscopic design. It was said that the inventor came up with the idea for the camera during World War I on a trench while peeping through a periscope. The double-lens design allows photographers to have a continuous view on the subject through the viewing-lens while the picture is being captured by the taking-lens, having a separate taking-lens and viewing-lens also reduces the shutter lag and speeds up the focusing process between shots. These attributes along with its exceptional build made it one of the cameras of choice in a period where every encounter counted.

Manufacturers continued to upgrade this medium-format camera in the 40s as its popularity soared. Being able to operate the camera at a waist-level instead of the eye-level conveniently opened up more creative possibilities, many notable photographers who we have come to know today, such as Richard Avedon, Imogen Cunningham, Irving Penn and Diane Arbus to name a few, were avid users of the twin-lens reflex camera, capturing every moment in both their personal and professional life.

Creativity and style are at the core of TACS’ philosophy, feeling particularly drawn to the creative versatility and the sophisticated design of the twin-lens camera, and also as a natural continuation for the Lens Series, TACS looks to the iconic vintage camera to create the new Automatic Twin Lens.

Japanese Craftsmanship, Inside and Out

The distinct multi-layer twin lens dial consists of 19 individual parts, and each one is hand-assembled by a TACS watchmaker in Japan. To ensure every single part is put together with the highest level of craftsmanship and precision possible, there is a limit of 10 timepieces a watchmaker can assemble daily. Peeking through the transparent twin lens reveals a 21-jewel, skeletonized Miyota 8N24 automatic movement, also handmade in Japan, rendering the timepiece a power reserve of 42 hours and a creation that is synonymous with Japanese craftsmanship inside and out.
