Aside from minor refinements, the design remains largely unchanged—a testament to its durability and functional excellence.

Its longevity—spanning over four decades—highlights both its historical significance and enduring practicality.\u003c\/p\u003e\n\u003cp\u003eThe overall design of this watch traces back to British MOD specifications.

In real-world use, the vast majority of cracked crystals occur in watches fitted with mineral glass—even when hardened. Sapphire significantly reduces this risk, making it particularly well suited to military, law enforcement, and active outdoor use.\u003c\/p\u003e\n\u003cp\u003eThe material is heat-treated during production to eliminate internal stresses and maximise strength, then typically finished with anti-reflective coatings for improved visibility. While more expensive than mineral glass, sapphire is now standard in higher-end watches—and even used in devices such as modern smartphones—due to its superior durability.\u003c\/p\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"MWC - Military Watch Company","offers":[{"title":"Default Title","offer_id":67687124435188,"sku":"DIV2001SSND\/715LI","price":249.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0055\/4172\/4260\/files\/DIV2001SSND_715LI_BS_w.jpg?v=1791023959","url":"https:\/\/mil-time.com\/fr\/products\/current-nato-pattern-quartz-military-divers-watch-non-date-variant-with-sapphire-crystal-and-10-year-battery-life-nato-stock-number-nsn-6645-99-157-3496","provider":"Tactico Logistics ROI ","version":"1.0","type":"link"}
