Frequently asked questions

What is the lug width of the Baume & Mercier Clifton 10278?

The lug width of the Baume & Mercier Clifton 10278 is 20 millimetres. This specific dimension indicates the distance between the two lugs of the case where the strap attaches. It represents a precisely calculated proportion for the 43-millimetre case diameter, ensuring aesthetic balance and stable wear.

Which strap is recommended for the Clifton 10278?

For the Clifton 10278 we recommend straps in alligator (for formal occasions), vegetable-tanned calf leather (for refined daily wear), shell cordovan (for those seeking robust texture and durability), or woven NATO (to emphasise the chronograph's sporting character). Your choice depends on usage context and personal preference regarding patina development and ageing.

How do you change the strap on a Baume & Mercier Clifton 10278?

The Clifton 10278 strap is replaced by acting on the spring bars connecting the strap to the case. Using a dedicated strap removal tool, you gently push the elastic pin inward, releasing the old strap. You then insert the new strap by aligning its lug with the case attachments and allow the spring to reposition itself. The operation requires care to avoid scratching the case.

Is the Clifton 10278 compatible with aftermarket 20mm straps?

Yes, the Clifton 10278 is fully compatible with any strap featuring a 20-millimetre lug width. You will find a wide range of quality aftermarket straps online, from specialised Italian artisans to international manufacturers. It is essential to always verify the lug width (20mm) before purchase to avoid compatibility issues.

How long does a leather strap last on a Baume & Mercier Clifton 10278?

Strap longevity depends on material and usage. A satin alligator strap, with ordinary care, lasts 4-6 years. Vegetable-tanned calf develops patina over time and may last 5-7 years with regular maintenance. Shell cordovan, being more robust, comfortably reaches 7-10 years. Sun exposure, heat and humidity accelerate wear. A replacement strap, rotated in use, significantly extends the lifespan of your entire strap collection.
