Strap for Classima 36.5 Automatic Stainless Steel / Diamond / MOP / Alligator

The lug width of the Baume & Mercier Classima 10222 is 18mm. This is the distance between the two inner lugs (spring bars) of the case and represents the essential technical specification for selecting compatible straps. To measure correctly, use a digital calliper positioned between the lugs at the lower part of the case.

For the Classima 10222, we recommend genuine alligator straps in natural or solid colours for formal occasions, or vegetable-tanned calf leather for versatile daily wear. Your choice depends on the intended use: alligator delivers pure elegance, whilst vegetable-tanned calf develops a natural patina over time that enriches the overall aesthetic. Rubber or NATO canvas straps represent contemporary alternatives suitable for summer months.

Strap replacement is a straightforward operation requiring no specialised tools. Position your watch on a soft surface, locate the spring bars (small metal cylinders holding the strap), and use a slender tool (such as a dedicated strap removal tool or the rounded tip of a butter knife) to slide the spring bar out of its slot. Remove the old strap and insert the new one, aligning the holes with the case lugs and ensuring the spring bar is fully seated.

Absolutely. The Classima 10222 accepts aftermarket straps of quality with a precisely 18mm lug width. Artisanal straps offer significant advantages over the original strap: superior aesthetic customisation, choice of premium leathers (alligator, shell cordovan, vegetable-tanned calf), unlimited colour options, and the ability to develop a unique patina over time. Always verify that the lug width matches exactly 18mm before purchase.

Strap longevity depends on material quality, frequency of wear, and maintenance practices. A high-quality alligator strap typically lasts 3–5 years with regular use; vegetable-tanned calf leather has comparable longevity but develops a patina that becomes more visually interesting over time. With occasional wear (2–3 times weekly), durability extends significantly. Proper care—avoiding excess moisture and gentle cleaning with a soft cloth—prolongs useful life. An 18-month warranty is standard for quality artisanal straps.
