Senator 1-36-01-01-02-36— lug 20mm

The lug width is 20 millimetres. This measurement is proportioned to the 40 mm case diameter and ensures the visual equilibrium characteristic of the model. Always verify by measuring internally between the lug attachments before purchasing an aftermarket replacement.

An alligator or vegetable-tanned calf leather strap represents the ideal choice, preferably in dark brown or cognac tones. These materials evolve naturally over time, developing a patina that reflects the watch's constructive philosophy. For daily wear, a thick-canvas NATO or vegetable-based rubber strap remains an excellent alternative.

Remove the original strap using a dedicated tool (spring bar tool) to extract the lugs from the lateral seats of the case. Insert the new strap's lugs in the opposite position, verifying they click securely. Avoid excessive force to prevent damaging the attachments. If unfamiliar with the procedure, entrust the task to a watchmaker or directly to Atelier Casati Milano.

Yes, provided the lug width is exactly 20 millimetres. However, an artisanal-quality strap (such as those offered by milanostraps.it) guarantees superior quality control compared to standard industrial production. Stitching, finishing, and natural leather ageing mark the difference in the long term.

With vegetable-tanned leather of quality and proper maintenance, an alligator or calf strap maintains functionality and aesthetics for 3–5 years of moderate daily wear. Durability depends on exposure to humidity, perspiration and direct sunlight. A strap preserved in a controlled environment and subjected to periodic maintenance (gentle cleaning, conditioning) can last substantially longer.
