MWC 24 Jewel 1980s Pattern 300m Automatic Military Divers Watch with Sapphire Crystal on a Steel Bracelet

Product Code: SUB/MIL/SS/AUBL These diver's watches are a modern remake of a 1980s model that we produced until around 35 years ago. The watch features a robust stainless steel case and is equipped with a high-performance automatic 24-jewel self-winding movement. We have made several upgrades to the original design, including a shatter and scratch-resistant sapphire crystal and an increased water resistance rating. The dial and caseback are both unbranded (referred to as sterile in the military), giving the watch a clean and uncluttered appearance. Historical and Technical Background Inspired by the 1980 UK MOD specification for automatic diver's watches (DEF STAN 66-4 [Part 1] Issue 3), this model retains key design elements such as the unidirectional bezel and boldly marked dial with tritium paint. The original MOD specification also called for a mineral glass crystal, as documented in the MOD file shown in the final two images. While staying true to the spirit of the original, this updated version incorporates modern improvements, such as the use of non-radioactive paint and the inclusion of sapphire crystal, as detailed below.

Synthetic sapphire is extremely strong, shatter-resistant, and scratch-resistant, making it ideal for military and security personnel, police officers, and active outdoor enthusiasts. These groups account for 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 are strengthened through a heat treatment process that removes internal stresses and are then coated with two layers of anti-reflective coating. Although sapphire crystals are more expensive, they offer superior longevity, resilience, and performance, justifying their use in higher-end watches. These models represent excellent value and are competitively priced for such a high-performance automatic watch. This watch combines the historical design and functional integrity of its predecessors with modern upgrades to meet the needs of today's professionals and enthusiasts.
