Strap for M 29 Classic Black / Bracelet

The M1-25-53-MB features a lug width of 22mm. This measurement should be verified by positioning a ruler across the distance between the two spring bar channels on the original strap. To ensure correct fitment, always confirm that your aftermarket straps respect this exact dimension.

For the M1-25-53-MB, we primarily recommend vegetable-tanned leather (aniline calf or Tuscan leather), as it respects the technical and understated aesthetic of the model. Alligator represents the ultimate choice for those seeking patina and longevity. NATO straps in canvas are ideal for emphasising functionality; structured rubber is the contemporary solution for humid climates or maritime activities.

Changing the strap on the M1-25-53-MB is straightforward: use a spring bar removal tool to gently push the original strap's anchor bar and extract it from the lug channels. Align the new strap by inserting one end first, then engage the spring mechanism of the second bar until fully seated. Verify that both sides are securely fastened before wearing the watch.

Yes, the M1-25-53-MB is fully compatible with quality aftermarket straps, provided they respect the 22mm lug width. Artisanal straps crafted in vegetable leather, alligator, or technical rubber deliver superior aesthetic and functional results compared to generic straps. Always verify that the material is suitable for daily wear and that finishing is executed with precision.

A quality leather strap, used daily, typically lasts 4-7 years before showing significant signs of wear. This timeline depends on intensity of use, climatic conditions, and material care. Vegetable-tanned leather, in particular, develops a noble patina over time; alligator straps can last beyond 10 years. Regular maintenance—gentle cleaning and occasional conditioning—significantly extends longevity.
