Baume & Mercier
Hampton 10025 (aka: MOA10025, M0A10025)— lug 18mm

The Baume & Mercier Hampton 10025 features an 18 mm lug width, as confirmed in the brand's official specifications. To verify independently, measure the distance between the two shoulders where the strap sits on the case: it should equal 18 mm precisely.

Selection depends on intended wear. For formal elegance, refined alligator or shell cordovan in warm brown tones accentuate the rectangular Art Deco identity. For daily use, vegetable-tanned calf leather in black or brown develops natural patina with time. For smart-casual wear, a dense cotton NATO maintains visual clarity without rigid formality.

The strap is secured via spring bars. To remove: use a dedicated tool or thin blade to gently push the spring bar inward, freeing the strap end. Repeat on the opposite side. Insert the new strap by aligning the holes with the case lugs and securing the spring bars until they click. Never force: movement should be smooth.

Any strap explicitly marked for 18 mm lugs is compatible. Always verify that the strap ends bear holes conforming precisely to 18 mm width. Milano Straps supplies customisable straps for your 10025, offering premium materials including alligator, shell cordovan, calf, and rubber.

Longevity depends on material and usage patterns. Alligator or vegetable-tanned shell cordovan straps typically last 3–5 years with moderate daily wear. Calf leather, more delicate, may require replacement after 2–3 years of intensive use. Lifespan extends significantly through rotation between multiple straps and protection from excessive moisture. Milano Straps provides 18-month warranty on custom straps made at Casati Milano atelier.
