FAQ

What is the lug width of the Baume & Mercier Clifton 10518?

The Baume & Mercier Clifton 10518 features a lug width of 20mm. This measurement is determined by the 40mm case geometry and remains constant across all examples of this reference. To verify the lug width, place a ruler on the inside shoulder of one lug and measure to the inside shoulder of the opposite lug: the result should be precisely 20mm.

What is the best strap for the Baume & Mercier Clifton 10518?

The optimal strap depends on intended use and colour preference. Deep grey alligator or oxblood calf leather maintain visual coherence with the case's minimalist design philosophy. For sports-oriented contexts, natural NATO cotton or black FKM rubber with radial texture are constructive choices that align with the 10518's functional ethos. The case's aesthetic simplicity requires that every strap choice be justified for coherence rather than variety.

How do I change the strap on the Baume & Mercier Clifton 10518?

The process requires a spring bar tool or small flat lever. Position the watch on a soft surface to prevent scratching. Locate the pins securing the strap to the case lugs: insert the tool into the small lateral hole of each pin and apply gentle pressure to dislodge it. Repeat on the opposite side. Slide the new strap through the lugs, aligning the pins until you feel a click of engagement. Verify that the strap sits flush and is fully secured.

Can I use an aftermarket strap that is compatible with the Clifton 10518?

Yes, all straps with a 20mm lug width are compatible. Milano Straps offers a curated selection of 20mm straps customisable in materials, colours and finishing options. It is essential to verify that the strap length does not impede proper closure and that passants or a deployante clasp do not contact the case. Bespoke leather straps represent the optimal choice for maximising comfort and precision fit.

How long does a natural leather strap last on the Clifton 10518?

Longevity depends upon material type, frequency of use and maintenance practices. Structured alligator or vegetable-tanned calf can maintain optimal condition for 4–6 years of daily wear, developing a desirable patina with time. FKM rubber demonstrates superior resistance to atmospheric agents and may endure 5–7 years. Cotton NATO, subject to reduced mechanical stress, can perform reliably for 7–10 years. Regular monthly cleaning, avoidance of prolonged moisture exposure and periodic rest intervals significantly extend lifespan. Casati Milano's atelier provides an 18-month warranty on all bespoke straps.
