Men’s Dive Watch 40 mm 30Ba- Mechanical Automatic Watches

Product Overview

The Men’s Dive Watch 40 mm 30Ba is a precision mechanical automatic timepiece designed for men who value durability, functionality, and classic diving aesthetics. Built around the reliable NH35 automatic movement, this watch delivers consistent performance without the need for a battery, powered instead by the natural motion of the wearer’s wrist. Encased in a robust 40mm design and protected by a scratch-resistant sapphire crystal, it’s engineered to withstand underwater conditions down to 30 bar (approximately 300 meters), making it suitable for recreational diving and water sports. The luminous markers and hands ensure excellent legibility in low-light environments, while the built-in calendar function adds everyday practicality. Whether you’re exploring ocean depths or navigating daily life, this watch combines technical reliability with timeless style.
