Diver's Watch Design with Heritage
Domed sapphire crystal
Made for everyday wear: Our watches feature highly scratch-resistant sapphire crystal that maintains its appearance even with daily use. The double anti-reflective coating minimizes unwanted reflections and ensures a clear view of the dial, even in challenging lighting conditions. The gently domed shape adds depth and enhances the watch’s premium appearance. This is how we combine durable materials with timeless aesthetics and everyday practicality.
The engine on your wrist: The TMI NH35
The NH35 is a bidirectional automatic caliber featuring Seiko’s patented Magic Lever System, which simplifies the winding mechanism and makes it more efficient. This system reduces winding time and extends the power reserve while using fewer components.
The rotor generates energy in both directions, allowing the watch to start with even the slightest movement. The shock-resistant Diashock system protects the mechanism from vibrations. Additionally, the seconds-stop function—activated by pulling out the crown—enables precise time setting.
With up to 41 hours of power reserve and a date function, the mechanical NH35 movement is a reliable companion for everyday life.
Maximum comfort. Thoughtfully engineered.
