Professional-Grade Dive & Tool Watch Standards
Many Promaster Dive watches are ISO 6425 certified, meaning they exceed strict requirements for water resistance, bezel strength, shock protection and underwater legibility. Features include screw-down crowns, unidirectional bezels, strong lume and pressure-tested construction. Paired with Eco-Drive or advanced quartz movements, these watches are built for harsh environments.
The aviation and land-based Promaster models offer equally strong functionality, with features such as slide-rule bezels, chronographs and extreme readability.
Materials, Movements & Real-World Durability
Promaster watches use stainless steel or Super Titanium™ for strength, corrosion resistance and reduced weight. Eco-Drive models offer months of power reserve, while select references incorporate satellite GPS or radio-controlled timekeeping for global accuracy. These pieces are designed to endure, making them ideal for demanding users.
