Strap for Legacy Machine N°1 LM1 Alain Silberstein Black Titanium

The lug width of the MB&F Legacy Machines 53.BTL.B is 20 millimetres. This dimension is essential for selecting compatible straps. To verify correct measurement, use a digital calliper and measure the internal distance between the watch lugs, ensuring the value is precisely 20mm. This measurement ensures proper fitment and prevents strap slippage during wear.

Alligator leather represents the optimal choice from both aesthetic and functional perspectives. The naturally rigid structure of alligator emphasises the sharp geometry of the titanium case, whilst its well-defined grain creates visual contrast that amplifies the overall design. For those preferring warmer tones, vegetable-tanned calf offers a patina that evolves gracefully over time. Alternative options include robust NATO fabrics and vulcanised rubber for a more contemporary interpretation.

To change the strap, use a spring bar tool with extreme care. Locate the small elastic pins connecting the strap to the watch lugs. Position the spring bar tool beneath the pin and gently push upwards until the pin retracts, releasing the strap. Repeat on the other side. Inserting the new strap follows the reverse procedure. For impeccable operation, avoid sudden impacts and work on soft cloth-protected surfaces to prevent scratching.

Yes, any strap with a 20mm lug width is compatible with the MB&F Legacy Machines 53.BTL.B. However, we recommend selecting materials of certified quality and rigid construction: the titanium case requires straps that maintain proper fit and do not deform with use. Milano Straps offers a curated collection of 20mm artisanal straps, selected for durability and aesthetic harmony with your timepiece.

Leather strap longevity depends on the material chosen and frequency of wear. An alligator strap with vegetable tanning, with appropriate maintenance (protection from excessive humidity and aggressive cleaning agents), can last 5-7 years of daily use. Calf leather, being softer, tends to wear more rapidly, averaging 3-5 years. Synthetic materials such as NATO or vulcanised rubber offer superior wear resistance, extending useful life to 8-10 years. The natural patina developed over time is a desirable characteristic, not a defect.
