Strap for M 29 Classic Cream / Strap

The lug width of the M1-25-57-LB is 22mm. This measurement indicates the distance between the pins that anchor the strap to the case lugs and is essential for selecting compatible straps. You can verify it by measuring the distance between the attachments with a calliper.

The M1-25-57-LB pairs exceptionally well with vegetable-tanned leather straps (cognac brown calf or shoulder leather), black alligator for formal contexts, or grey-dark NATO woven sailcloth to emphasise its instrumental vocation. Your choice depends on use: sartorial elegance, maximum formality, or technical versatility.

Strap replacement is straightforward: use a spring bar tool to gently lift the pin anchoring the strap to the case (work from the outer sides to avoid contact with the crystal), remove the old strap and insert the new one aligning the holes. If you don't own the tool, contact a local watchmaker or our experts for professional replacement.

Any strap with a 22mm lug width is compatible with the M1-25-57-LB. Milano Straps offers a dedicated collection of artisanal straps in this size: Tuscan vegetable-tanned leather, alligator, shell cordovan, NATO woven fabric and FKM rubber. All are packaged and shipped within 48 hours.

A vegetable-tanned leather strap, subject to moderate daily wear (4-5 days a week), maintains structural integrity for 3-5 years. Alligator, thanks to its more resistant scalloped texture, can last 6-8 years. The patina that develops visually documents this ageing. An FKM rubber strap offers superior longevity (10+ years) but less aesthetic evolution.
