GMT 39mm Men's Diver Watch 20ATM Stainless Steel

GMT Diver Built for Everyday Reliability

The GMT Watch Men's 39mm Diver is designed for dependable performance in and out of the water. With dual time display, a clear luminous dial, and robust 316L stainless steel construction, it offers a practical balance of function, legibility, and comfort for daily wear and demanding conditions.

The 39mm case (48.5mm lug-to-lug, 12.8mm thick) provides a versatile fit that wears comfortably on wrists from approximately 13-18cm. Crafted from 316L solid stainless steel, the case and clasp feature a brushed and polished finish for a clean, professional look. The solid screw-down caseback and screw-down crown work together with precise engineering to deliver 20ATM / 200m water resistance, suitable for swimming, snorkeling, and recreational diving. Inside, a Swiss Ronda 515-24H GMT quartz movement powers the watch, providing accurate timekeeping and an additional 24-hour hand to track a second time zone at a glance.

The black dial is designed for clarity, with a date display and high-contrast markers filled with vintage-style super luminous powder that emits a yellow‑green glow in low light or underwater. Matching luminous hands ensure the time remains easy to read in dark environments. A bubble‑style mineral glass crystal with anti-dazzle blue coating improves legibility by reducing reflections, while maintaining impact resistance suitable for everyday use. The 20mm steel bracelet and solid steel plate buckle provide a secure, stable fit, and the overall watch length of about 220mm is easily adjustable by sizing the bracelet links.
