Strap for Classic Date 37 Stainless Steel / Silver / Bracelet

The lug width is precisely 18mm. This intermediate size is specific to this model and requires accurate measurement with a calliper between the two lugs on the case. It does not fall within common commercial standards, so compatibility must be verified before purchasing a strap.

For the dress watch character of this timepiece, we recommend straps in alligator or calf leather with vegetable tanning. Alligator maintains maximum formality with its ordered scales, whilst natural calf adds chromatic versatility. For daily use, nato in neutral colours or structured rubber ensure comfort and practicality without sacrificing the stainless steel case's elegance.

The change is accomplished via the horizontal spring bars that connect the strap to the case. Using a spring bar tool or plastic stick, compress the bars slightly and extract the strap from its seat. The new 18mm strap is inserted into the same holes, ensuring the bars lock symmetrically. To avoid damaging the stainless steel case, avoid sharp metal tools.

Yes, many specialised artisans produce bespoke 18mm straps or maintain catalogues dedicated to this width. Quality depends on material selection: vegetable-tanned leather, quality leather soles, and hand-stitching guarantee longevity. We recommend suppliers who document their construction process and offer guarantees on workmanship.

A quality leather strap with vegetable tanning and artisanal construction lasts an average of 5–7 years with moderate daily wear. The natural patina that develops increases aesthetic value. Factors such as ambient humidity, sun exposure, and frequency of use influence longevity. Periodic maintenance with neutral creams extends its life.
