Strap for Clifton Automatic Two Tone

The Baume & Mercier Clifton 10139 features an integrated lug width of 20 millimetres. This measurement, taken internally between the two spring bar attachment points, is a rare dimension in contemporary dress watches and requires specifically compatible straps.

The ideal strap depends on intended use and personal preference. For formal occasions, an alligator strap in dark brown or black offers discreet elegance. Shell cordovan, with its evolving patina, establishes aesthetic connection with rose gold cases. Fine-grain calf in cognac ensures daily versatility, whilst a canvas and leather NATO strap permits casual transitions while maintaining harmonious proportions.

The integrated lugs of the 10139 do not permit autonomous strap replacement using domestic tools. Strap changes require care: it is advisable to consult a specialist or contact the Casati Milano atelier, where trained technicians perform the operation whilst preserving case integrity and spring bar functionality.

Yes, Milano Straps offers a dedicated collection of 20mm straps compatible with the 10139, available in alligator, shell cordovan, calf leather and rubber. These straps are crafted to harmonise with the case proportions and may be customised in length, initials and stitching thread selection.

Leather strap durability depends on frequency of use, climatic conditions and material quality. On average, a quality artisanal alligator or shell cordovan strap maintains structural integrity for 3–5 years of regular wear. Natural patina increases over time, creating character and uniqueness. Milano Straps guarantees 18 months on straps crafted by the Casati Milano atelier.
