Strap for Saint-Imier Date 38.5

The lug width is 20mm. This measurement corresponds to the internal distance between the two lug tubes on the case and is essential for purchasing compatible straps. We recommend measuring directly on your watch using a digital calliper or a millimetre ruler positioned perpendicular to the case plane, from the inside of one lug tube to the other.

The Saint-Imier pairs exceptionally well with alligator or premium calf leather straps. For a classical aesthetic, we recommend vegetable-tanned leather that develops a natural patina over time. For everyday versatility, rubber or cotton/nylon NATO straps offer durability and practicality. For a bespoke premium experience, Casati Milano creates made-to-measure straps with direct leather selection and artisanal finishing.

Strap replacement requires a specific tool called a spring bar tool. Position the tool horizontally beneath the lug tube and apply gentle upward pressure to compress the internal spring. Once compressed, remove the tube. Repeat on the opposite side, then slide the new strap into place until you feel the locking click. Alternatively, entrust the task to a specialist watchmaker for zero risk of damage.

Absolutely. Any quality strap constructed for a 20mm lug width is compatible with the L2.766.4.52.6. Straps from milanostraps.it are customizable in length, colours, initials, and stitching thread type, ensuring a reliable solution without compromising construction quality. For bespoke execution with personal leather selection and 18-month warranty, Casati Milano provides a complete artisanal experience.

Durability depends on material, construction, and environmental wear. An alligator or vegetable-tanned calf leather strap worn daily has an average lifespan of 2-3 years before the leather shows visible wear (creasing, permanent fold marks). Rubber or NATO straps resist up to 5-7 years. The natural patina developed by vegetable-tanned leather is an appreciated aesthetic characteristic, not a defect: it indicates authenticity of use.
