The Horological Machines HM10-OW, seen from the bench

The MB&F Horological Machine N°10 Panda Only Watch features a 45mm case in titanium grade 5 or stainless steel with a distinctive articulated architecture.

The 20mm lug width is essential for strap compatibility with this architectural timepiece from the Horological Machines family.

Frequently asked questions

What is the lug width of the MB&F Horological Machines HM10-OW?

The lug width of the MB&F HM10-OW is 20 millimetres. This measurement represents the distance between the two lateral pins (lugs) where the strap is threaded. A precise measurement is essential to ensure total compatibility and smooth strap passage without structural stress.

Which strap is best paired with the MB&F Horological Machines HM10-OW?

For the MB&F HM10-OW, we recommend a strap in alligator leather with vegetable tanning or high-quality calf leather. These materials dialogue elegantly with the sculptural and contemporary character of the titanium/steel case. For more versatile use, a NATO strap in technical fabric offers exceptional practicality whilst maintaining aesthetic coherence with the model's profile of radical innovation.

How do I change the strap on my MB&F HM10-OW timepiece?

To replace the strap, procure a spring bar tool for pin removal. Position the tool gently on the lateral lug, applying pressure to compress the internal metal pin. Once the pin is released, remove the old strap and thread the new one, aligning the holes with the pins. Press until you hear a click, verifying correct positioning before releasing.

Is the aftermarket strap compatible with the MB&F HM10-OW?

Yes, any strap with a 20mm lug width is compatible with the HM10-OW. However, we recommend selecting straps crafted by artisans specialising in haute couture leather work, as the architectural profile of the case and the calibre of the watch's manufacturing excellence require an equally considered and meticulously executed strap.

How long does a leather strap last on the MB&F Horological Machines HM10-OW?

The lifespan of a leather strap depends on frequency of use, exposure to humidity, and the quality of the material selected. A strap in alligator or calf leather with vegetable tanning, if subjected to careful maintenance and moderate use, can last 3 to 5 years before requiring replacement. The natural patina that develops over time is a desirable aesthetic characteristic, not deterioration.
