Strap for Horological Machine N°1 HM1 Black

The lug width of the MB&F Horological Machines 10.T41WBL.O is 20mm. This dimension is measured from the centre of the upper lug hole to the centre of the lower lug hole and ensures compatibility with quality aftermarket straps.

For this white gold timepiece, we recommend an alligator strap with vegetable tanning, which creates visual harmony with the sculptural case. Alternatively, premium calf with a waxy finish offers daily versatility whilst maintaining elegance. For a more contemporary aesthetic, a cotton NATO or FKM rubber strap accentuates the unconventional character of the design.

To change the strap, use a dedicated tool (spring bar remover or small flat screwdriver) to remove the spring bars from the lugs. Gently extract the old strap and insert the new one, ensuring the spring bars are firmly secured and aligned. Always verify that the strap is 20mm wide for correct mounting.

Yes, you may use quality aftermarket straps provided they have a 20mm lug width. Milano Straps offers a carefully curated selection of 20mm straps in various materials and colours, all compatible with your timepiece and ready for dispatch.

Durability depends on material and usage. Vegetable-tanned alligator can last 5-8 years with regular maintenance. Premium calf typically resists 3-5 years. Shell cordovan, owing to its density, can reach 8-10 years. FKM rubber or polyurethane has a durability of 2-4 years. Regular maintenance (cleaning, conditioning) significantly extends lifespan.
