Issued in the 1950s by International, this is an extremely rare "W10/445-5890" NATO dial variant of the masterpiece Mark 10. It was supplied in the 1950s after the change in the British Army's administration code from the Dirty Dozen, which was adopted in the 1940s. Compared to the standard Mark 10, this variant is extremely scarce, making it a rarity in the market.
The unique dial, bearing the inscription "W10/445-5890," known as the NATO dial, exudes a distinct presence. Coupled with the pleasing patina of aging and the hefty snap-back waterproof case known as the "Hammet," it showcases a magnificent military aesthetic. It is equipped with the renowned International Cal.83, representing the pinnacle of craftsmanship.
