MB1 comes withBlack/Brown Leather Straps

MB1 - our first series inspired by the '70s wedge era car design movement. The wedge era in car design was characterized by a distinctive angular aesthetic. This angular aesthetic, reminiscent of iconic cars like the DMC DeLorean, Lamborghini Countach, and Aston Martin Bulldog, is brought to life in MB1. It's designed as if it came from the 1970s but in another dimension; with its classic size, multi-faceted details, and intriguing design similarity came across the past and the future.

L02 comes with a black enamel-coated dial

The case is made of 316L stainless steel with a distinct finish, featuring angular lugs and a side profile. Achieving exceptional magnetic resistance of up to 4800 A/m, the calibre is enclosed in a Faraday cage. MB1 is a tribute to an era that continues to inspire and captivate.

The wedge-shaped case design is inspired by the ‘70s ‘80s wedge era car design and the modern Tesla Cybertruck design. It is characterized by a distinctive angular aesthetic.

The case has a distinctive finish. Linear brushed on the case side and lug top surface, mirror polishing on the bezel and edging of the lugs. These variations enhance the profile sharpness and catch reflection beauty.

While more expensive to manufacture than the Seiko NH series, the cal.9039 offers slimmer dimensions, a higher beat rate of 28,800 bph, and a smoother sweep for the second hand. These features enhance both the wearability and timekeeping accuracy of the watch.

Featuring a double-domed sapphire lens and a 316L steel case, the MB1 offers a thin 12mm thickness (10mm without lens). The lens comes with both an AR (anti-reflection) coating and an anti-fingerprint coating. The slim Miyota 9039 integrated into the MB1 case offers a perfect presence on the wrist.


The readability of the time at a glance is the key in most conditions. Yet, we deem to create a dial has the capability of communicating the effort that it is restrained but not boring.

All MB1 watch hands and indexes are multi-faceted, carrying an abundance of thickness. The multi-faceted edges to the hands and indexes are in equal measure with the case in perfect harmony. It is designed to reflect light and sharpness.


During the "50s, the adventure and exploration movement triggered the "tool watch era". A clutch of watches was made to withstand the detrimental effects of magnetism on a watch's calibre. This is achieved by enclosing the calibre in a Faraday cage.

Our Faraday cage delivers a high level of antimagnetic protection which resists exposure to a direct current magnetic field of 4800 A/m in ISO 764:2020 standard.
