Strap for Legacy Machine N°1 LM1 White Gold

The lug width of the MB&F Legacy Machines 01.WL.W is precisely 20mm. This measurement is essential for strap compatibility. To verify, measure the internal distance between the two spring bars on your case; the measurement must be exactly 20mm, as incorrectly sized straps may cause slippage or irregular wear.

We recommend an alligator strap with vegetable tanning in chocolate brown or deep black. The natural texture of the scales dialogues perfectly with the complex internal architecture of the movement, whilst the patina-developing capability creates personal temporal narrative. Vegetable-tanned calf leather in anthracite grey or navy blue represents an equally compelling alternative.

Strap replacement requires a spring bar tool (specialist device). Locate the spring bars within each lug, apply gentle downward pressure to raise the spring mechanism, then remove the old strap terminus. Insert the new strap until you hear the spring bar click into position. If inexperienced, we recommend engaging a qualified watchmaker for this operation.

Yes, specialised artisanal manufacturers offer 20mm straps compatible with this model. Milano Straps curates a selection of premium leather straps (alligator, calf, shell cordovan), vulcanised rubber, and technical textiles. Our 20mm collection has been deliberately selected to address the aesthetic and functional requirements of horologically complex timepieces such as the Legacy Machines.

Longevity depends upon material quality, usage patterns, and maintenance discipline. A premium alligator or vegetable-tanned calf strap, subjected to ordinary maintenance (regular cleaning, annual conditioning), can maintain functionality and aesthetic integrity for 5-10 years. Daily use in humid environments or excessive perspiration exposure shortens this period. The patina that develops is natural characteristic evolution, not deterioration: it constitutes the temporal signature of your personal relationship with the timepiece.
