Frequently asked questions

What is the lug width of the MB&F Legacy Machine No.1 01.SL.C?

The MB&F Legacy Machine 01.SL.C features a 20-millimetre lug width. This measurement represents the distance between the two lugs where the strap is attached. It is essential to verify this dimension before purchasing an aftermarket strap to ensure complete compatibility and secure attachment.

What is the best strap for the MB&F Legacy Machines 01.SL.C?

The optimal strap depends on your intended use and personal preferences. For maximum elegance, we recommend alligator in matte black or dark brown with vegetable tanning, which dialogues beautifully with the titanium case. For daily practicality, a robust cotton NATO or FKM rubber offer comfort and durability. Shell cordovan represents the ideal compromise between aesthetics and versatility.

How do I change the strap on the MB&F Legacy Machine 01.SL.C?

Strap replacement requires specific tools: a spring bar tool and a stable work surface. Position the watch horizontally, gently insert the tool under the pin to compress the internal spring, and slide the pin out of its seat. Repeat on the other side. Insert the new strap by reversing the operation. If you are not experienced, it is advisable to entrust the task to a professional service.

Can I use an aftermarket strap compatible with the MB&F 01.SL.C?

Yes, absolutely. Any strap with a 20-millimetre lug width is technically compatible. However, consider the aesthetic harmony: the Legacy Machine deserves straps of equivalent construction quality. Choose premium leather, robust textiles, or technical rubber. Avoid inexpensive straps that would not honour the value of your timepiece.

How long does a leather strap last on the MB&F Legacy Machine 01.SL.C?

Durability depends on leather quality and intensity of use. Premium alligator or shell cordovan can last 3–5 years in daily wear, developing a captivating patina over time. Standard calf lasts 2–4 years. Vegetable tanning extends service life compared to industrial methods. Regular maintenance—gentle cleaning and light conditioning—significantly prolongs longevity.
