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.\u003c\/p\u003e\n\u003ch3\u003eHistorical and Technical Background\u003c\/h3\u003e\n\u003cp\u003e\u003cmeta charset=\"utf-8\"\u003eInspired 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.\u003c\/p\u003e\n\u003ch3\u003eKey Features and Upgrades:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMovement:\u003c\/strong\u003e High-performance automatic 24-jewel NH35A self-winding movement with a 41-hour reserve\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCrystal:\u003c\/strong\u003e Shatter and scratch-resistant sapphire crystal with anti-reflective coating\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWater Resistance:\u003c\/strong\u003e 300m \/ 1000ft\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDesign:\u003c\/strong\u003e Sterile dial and caseback for a clean appearance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVisibility:\u003c\/strong\u003e Uses Luminova for excellent nighttime visibility\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStrap:\u003c\/strong\u003e 20mm Stainless Steel Bracelet\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWater Resistance:\u003c\/strong\u003e 300m \/ 1000ft\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCrown:\u003c\/strong\u003e Screwdown locking\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCaseback:\u003c\/strong\u003e Screw caseback\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003eWidth: 45mm including the crown, 40mm excluding the crown\u003c\/li\u003e\n\u003cli\u003eThickness: 15mm\u003c\/li\u003e\n\u003cli\u003eCrystal Diameter: 31mm\u003c\/li\u003e\n\u003cli\u003eLug to Lug: 49mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 89.5g\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMovement:\u003c\/strong\u003e 24-jewel NH35A with a 41-hour reserve\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStrap:\u003c\/strong\u003e 20mm Stainless Steel Bracelet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackaging:\u003c\/strong\u003e Giftbox included\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eBenefits of Sapphire Crystal:\u003c\/h3\u003e\n\u003cp\u003eMany customers ask about the benefits of sapphire crystal over standard mineral crystal. 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.\u003c\/p\u003e\n\u003cp\u003eOur 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.\u003c\/p\u003e\n\u003chr\u003e\n\u003cp\u003eThese models represent excellent value and are competitively priced for such a high-performance automatic watch.
