Frequently asked questions

What is the lug width of the Baume & Mercier Clifton 10057?

The lug width of the Baume & Mercier Clifton 10057 is 20 millimetres. This is the distance between the watch lugs and is essential for selecting a compatible strap. All 20mm straps will fit perfectly on this model.

Which strap is recommended for the Baume & Mercier Clifton 10057?

For the Clifton 10057, we recommend straps in alligator or vegetable-tanned calf leather, as these enhance the watch's classical elegance. Alligator features a refined, tapered texture, whilst calf leather offers a more understated appearance. A navy cotton NATO strap also presents an appealing casual alternative for this timepiece.

How do I change the strap on my Baume & Mercier Clifton 10057?

The strap is changed by using a spring bar removal tool to extract the elastic pins (spring bars) connecting the strap to the case lugs. Insert the tool beneath the pin, lift gently, and the pin will release from its seat. Repeat on the other side. To install a new strap, align the holes and reinsert the spring bars until you hear a click.

Can I use third-party aftermarket straps on my Baume & Mercier Clifton 10057?

Absolutely. The Clifton 10057 with its 20mm lugs is fully compatible with high-quality artisanal aftermarket straps. Milano Straps offers fully customisable straps in leather, with deployant options and stitching choices, allowing you to adapt your watch to your style without affecting its value.

How long does a leather strap last on the Baume & Mercier Clifton 10057?

A quality leather strap (alligator, calf, shell cordovan) typically lasts 2-4 years with daily wear, depending on tanning method and maintenance. Vegetable-tanned leather ages gracefully and develops a rich patina over time. Milano Straps guarantees 18 months on all bespoke straps, with restoration or replacement options available beyond the warranty period.
