Description
AM339M is built for depth, precision and mechanical performance.
Powered by a reliable automatic Miyota 8215 movement, this model operates without a battery and winds itself through natural wrist movement. It also supports manual winding for consistent accuracy.
The solid 316L stainless steel case provides durability and weight, giving the watch a substantial presence on the wrist. Designed to meet diver specifications, it offers 20ATM (200m) water resistance, making it suitable for swimming and diving.
The sapphire crystal with anti-reflective coating delivers strong scratch resistance and clear visibility in different lighting conditions. High-intensity luminous markers ensure readability in low light or underwater environments.
Mechanical. Solid. Built for performance.

Enhanced Water Resistance
Engineering over excess.
The Signature Series is built around automatic mechanical movement.
No battery. No charging. The watch runs through motion and mechanical precision.
Each model is constructed with a solid metal case and scratch-resistant crystal, designed for long-term wear rather than short-term trends.
Proportions remain controlled.
Presence remains confident.
Enhanced water resistance supports daily exposure and active use without compromising refinement.
This is not fashion timekeeping.
It is mechanical ownership, worn daily, built to last.
