A fusion of urban grit and futuristic design - the SEVENFRIDAY SF M1B/01 “Urban Explorer” is a standout piece within the M-Series lineup, created for those who navigate the city with curiosity and intent. Blending layered construction with industrial detailing, it reflects SEVENFRIDAY’s signature approach to modern watch design.
Inspiration & Design
The “Urban Explorer” draws its character from the city - from industrial textures to the rhythm of movement and discovery. Its multi-level dial reveals a complex composition of stamped pattern plates, overlapping discs, and the signature “Y-wing” bridge overlay.
These elements create depth, contrast, and a constant sense of motion, offering a dynamic visual experience with every glance.
Dial & Case Details
Housed in a 47.6×47mm square-cushion stainless steel case, the M1B/01 features a dark blue PVD “animation ring” paired with black grooved bezel lines, creating strong visual contrast and detail.
The hardened K1 mineral crystal, treated with anti-reflective coating, protects the dial while maintaining clarity across its layered construction.
Movement & Features
The M1B/01 is powered by a customised Miyota 8215 automatic movement, delivering reliable performance with an approximate 40-hour power reserve.
An embedded NFC chip within the caseback allows for secure authentication and registration via the SEVENFRIDAY app, reinforcing the brand’s modern, connected approach.
Bracelet / Strap & Wearability
The watch is fitted with a distinctive strap combining blue denim with black calfskin leather, finished with a beige-stamped lining for added comfort.
Despite its bold case size, the ergonomic construction ensures a secure and comfortable fit for daily wear. With 3ATM water resistance, it is suited for everyday urban use.
Collector Positioning
The M1B/01 “Urban Explorer” is for those drawn to industrial design and layered aesthetics - a watch that reflects individuality, movement, and the energy of modern city life.
