Product Code: DIV/82SS/AUNDBL

This diver's watch is a modern remake of one of our 1980s models, specifically developed for a U.S. contractor who secured a large order for their client. The watch features a robust stainless steel case and a high-performance automatic 24-jewel self-winding movement. Significant upgrades from the original model include a shatter- and scratch-resistant sapphire crystal and an enhanced water resistance rating.

Historical and Technical Background:

This model takes inspiration from the 1980 UK Ministry of Defence specification for automatic diver’s watches (DEF STAN 66-4 [Part 1] Issue 3). It retains hallmark features such as the unidirectional bezel and clearly legible dial, originally marked with tritium.

In this modern version, we’ve swapped the now-obsolete tritium for non-radioactive Luminova and replaced the original mineral glass crystal with ultra-durable sapphire. The final two images show a scan of the original MOD spec file.

Benefits of Sapphire Crystal

Many customers inquire about the advantages of sapphire crystal over standard mineral crystal. Synthetic sapphire is exceptionally strong, shatter-resistant, and scratch-resistant, making it ideal for military and security personnel, police officers, and active outdoor enthusiasts. These characteristics are highly valued by over 70% of our customer base.

Our observations show that over 90% of incidents involving cracked watch crystals occur with mineral glass. Even hardened mineral crystals do not match the durability of sapphire. Sapphire crystals undergo a heat treatment process to remove internal stresses, enhancing their strength. They are then coated with two layers of anti-reflective coating, providing superior clarity and durability. While sapphire crystals are more expensive, they offer unparalleled longevity, resilience, and performance, justifying their use in higher-end watches.

This MWC diver's watch combines military-grade specifications with modern durability and flexibility, making it an excellent choice for professionals and enthusiasts alike. Its robust features, coupled with the option to customize the strap, ensure it meets the diverse needs of its users.
