Key Features

• Eco-Drive Technology – This advanced movement converts any light source into energy to power the watch, ensuring continuous operation without battery changes. The B873 base movement delivers precise timekeeping and includes a 3-hand date display for everyday functionality. Ideal for travelers and adventurers, Eco-Drive offers sustainable reliability whether you’re on land or underwater.
• ISO-Certified Dive Watch – Meeting stringent international standards for diving watches, this model is built to perform at depths up to 300 meters (0300M). Its screw-back case and screw-down crown ensure water resistance and protect internal components from pressure and moisture, making it a trusted companion for recreational and professional diving.
• Durable Polyurethane Strap & Buckle Clasp – The black polyurethane strap offers exceptional comfort, flexibility, and resistance to saltwater and UV exposure. Paired with a secure buckle clasp, it ensures a snug, adjustable fit during active use, whether swimming, snorkeling, or exploring coastal environments.
• Anti-Reflective Curved Mineral Crystal – The curved mineral crystal features an anti-reflective coating that minimizes glare and enhances legibility in bright underwater or surface conditions. This design not only improves visibility but also adds a sleek, modern aesthetic to the watch’s overall profile.
• Stainless Steel Case & Bold Design – Crafted from silver-tone stainless steel, the 48mm round case delivers a robust yet refined presence on the wrist. The black dial contrasts sharply with luminous markers and hands, ensuring clear readability in low-light underwater environments.
