Strap for Legacy Machine N°1 LM1 Alain Silberstein Red Gold

The MB&F Legacy Machines 53.RL.FS is fitted with a lug width of 20mm. This measurement is integral to the design of the 42.5mm case and determines compatibility with aftermarket straps. Proper lug width measurement is performed by positioning a calliper from the inner wall of one lug to the inner wall of the other, completely excluding the case shoulder.

Several solutions are recommended for the 53.RL.FS depending on use and aesthetic preference. Dark brown or black alligator offers maximum sophistication and dialogues perfectly with the patina of rose gold. Vegetable-tanned calf provides a more subdued and softer option. High-density nylon NATO straps ensure sportive versatility. Composite rubber straps are ideal for daily use and environmental exposure. All 20mm straps are suitable for this model.

Strap replacement on the 53.RL.FS is accomplished using spring bars positioned within the lug seats. Using a dedicated spring bar tool, gentle pressure is applied to the pin to extract it from its seat, allowing removal of the previous strap. The new strap is inserted by aligning its holes with the lug and gently pushing the pin until it engages. The procedure requires care to avoid damaging the rose gold case.

Yes, thanks to the standardisation of 20mm lug width, the 53.RL.FS strap is fully compatible with any other watch featuring the same lug width. Many prestige brand models use this measurement. However, it is essential to verify your watch's lug width before purchase, as even minor variations (19mm, 21mm) render the strap incompatible.

A quality leather strap (alligator or calf) worn daily on the MB&F Legacy Machines 53.RL.FS has an average lifespan of 3-5 years, varying according to environmental conditions, exposure to moisture and sunlight, and frequency of use. Appropriate water-repellent treatment and protected storage when not worn extend longevity. Composite rubber and NATO straps typically last longer, 5-7 years, due to increased resistance to environmental and mechanical wear.
