Strap for Legacy Machine LM101 Moser Funky Blue

The MB&F Legacy Machines 51.SL.MB features a lug width of 20mm. This dimension is precise and requires straps specifically engineered for this width, ensuring the strap thickness is proportionate to the case geometry.

The optimal strap choice depends on intended use. For formal elegance, we recommend alligator with vegetable tanning or Hermès calf. For daily robustness, a high-density nylon NATO. For marine environments, vulcanised rubber with brushed texture. All must feature a 20mm lug width.

The Legacy Machines 51.SL.MB utilises standard spring bar pins. Position the watch on a protective work surface, use a spring bar tool to extract the pin from the lower lug position, slide out the old strap, insert the new 20mm strap, and re-insert the pin until it locks into position.

Yes, any strap with a 20mm lug width is technically compatible. However, we recommend verifying that the strap thickness is visually proportionate to the case lug. Undersized straps will create visual imbalance, whilst oversized straps will weigh down the case-to-wrist transition.

A premium leather strap (alligator, Hermès calf, shell cordovan) used daily lasts 3–5 years before replacement is necessary. With occasional use, longevity extends to 7–8 years. Leather develops a natural patina that enhances aesthetics over time, though internal structure inevitably deteriorates through repeated flexion.
