Frequently asked questions
What is the lug width of the MB&F Legacy Machines 05.WSL.B1?
The lug width of the MB&F Legacy Machines 05.WSL.B1 is 20mm. It is measured between the two attachment pins on the case. It is essential to verify this dimension before purchasing a replacement strap, as even a slight variation compromises proper fitment.
Which strap is recommended for the MB&F Legacy Machines 05.WSL.B1?
For this haute horlogerie timepiece, we recommend alligator for aesthetic restraint, calf leather with vegetable tanning for a patina that evolves over time, or satin-finished NATO for those seeking daily practicality. We advise against synthetic materials: the MB&F deserves authentic and premium leathers.
How do I change the strap on the MB&F Legacy Machines 05.WSL.B1?
The change requires a spring bar tool (a small specific instrument). Place the watch on a soft surface, position the tool beneath the attachment pin, apply gentle downward pressure to release the internal spring, and slide the pin out of the lug. Repeat on the other side. If in doubt, contact Atelier Casati Milano for professional replacement.
Can I use a compatible aftermarket strap with the MB&F Legacy Machines 05.WSL.B1?
Yes, provided it is certified 20mm and made from quality materials (full-grain leather, robust NATO, technical FKM rubber). Avoid inexpensive or synthetic products: an MB&F piece deserves straps that age with dignity and maintain their finishing quality.
How long does a leather strap last on the MB&F Legacy Machines 05.WSL.B1?
A quality leather strap (alligator, vegetable-tanned calf) lasts 3-5 years with responsible daily wear, developing patina and character. Longevity depends on sun exposure, humidity, and frequency of wear. A NATO strap lasts longer (5-7 years) thanks to cotton robustness, whilst FKM rubber has similar durability to NATO if not exposed to extreme temperatures.
