Strap for Linea 27mm Quartz MOP / Diamond Bezel

The Baume & Mercier Linea 10013 has a lug width of 18 millimetres. This measurement, taken between the inner shoulders of the case, determines compatibility with aftermarket straps. To verify, use a digital calliper positioned between the two internal attachment points of the case.

The ideal strap depends on usage and the proportions of the 27mm case. Natural alligator with dignified patina offers elegant sophistication for formal occasions. For daily wear, vegetable-tanned calf or shell cordovan ensure durability and develop patina over time. For summer, a silk NATO maintains lightness whilst preserving elegance.

To change the strap, remove the spring bars that hold the original strap to the lugs. Using a dedicated tool—available from professional watchmakers or specialist suppliers—press the spring bar inward to release the old strap. Insert the new strap, aligning the holes with the case lugs, and allow the spring bar to snap back. Casati Milano offers installation service by appointment.

Yes, the Linea 10013 is fully compatible with 18-millimetre aftermarket straps. Milano Straps provides a dedicated range of straps in this size—alligator, calf, shell cordovan, NATO, and rubber—ready for dispatch and customisable in length, colour, and stitching details.

Leather strap durability depends on tannery quality and intensity of use. An artisanal alligator or shell cordovan, with moderate use and regular maintenance, retains structural integrity for 4–6 years. Standard calf lasts 2–3 years under daily wear conditions. Milano Straps' warranty covers 18 months; beyond that period, wear and patina development are natural and manageable with conditioning.
