BOLDR Brings Back the Slide Rule Bezel with the new Expedition Enigmath

While math was never my strong suit in school, I have to say, I’m very excited for Singapore-based BOLDR’s Expedition Enigmath. Designed to harken back to the pre-digital age, the Enigmath is a perfect example of design-led charm with a tactile appeal.

The main feature of this watch is its slide rule bezel, which operates as a circular analog calculator. In the early 20th Century, this ingenious tool was used to perform various mathematical calculations and was adapted for tool watches often associated with aviation in the 1950s. By rotating the bezel, users can multiply, divide, and perform other operations without the need for your calculator app. This hands-on approach to calculation not only pays homage to historical methods but also offers a unique and practical feature for those who appreciate the tangible connection to their tools.

Crafted with precision and designed for the adventurous spirit, the Expedition Enigmath boasts a robust build with 200 meters of water resistance. The 41mm stainless steel case features both sandblasted and polished finishing in a style that will be familiar to fans of BOLDR’s previous watches. These watches have old-fashioned tool watch vibes with just a small nod to contemporary design tropes in the use of color on the dial and some subtle bits of case work. The Enigmath houses a Japan-made Miyota 9039 automatic movement, offering self-winding capabilities, hacking seconds, and an impressive 42-hour power reserve. The matte-texture ombré dial in green, blue, or black, coupled with Swiss Superluminova BGW9 on custom hands, provides optimal visibility even in low-light conditions. 

The Expedition Enigmath is available now, equipped with a rugged green canvas strap, via BOLDR’s website for $599.
