Strap for Master Collection 29 Two Tone Rose / Black

The lug width of the Longines Master Collection L2.257.5.59.7 is 15mm (0.59 inches). This measurement represents the distance between the two lugs of the case and is specific to this ladies' model. To verify it, use a digital calliper positioned parallel to the case poles. A tolerance of ±0.2mm is acceptable for aftermarket strap compatibility.

The choice depends on usage and aesthetic preferences. For formal elegance, we recommend vegetable-tanned alligator in cognac brown, which develops a rich patina over time. For everyday versatility, box calf in black or burgundy maintains refined proportions. For sporty interpretations, canvas NATO or vulcanized rubber straps transform the model without compromising the brand's identity. Japanese shell cordovan represents the choice for collectors who view the strap as an autonomous element of value.

Changing the strap on this model requires simple tools: a spring bar tool and a protected work surface. Position the watch with the dial facing downwards, locate the pins securing the strap to the lugs, and gently compress the pin with the tool until it is freed from its seat. Remove the old strap and insert the new one by sliding the pin until you hear the locking click. Verify that the pin is completely seated. Avoid sudden movements that could damage the case or crystal.

Yes, Milano Straps offers a collection dedicated to 15mm straps, ready for dispatch and customisable in length, stitching thread and initials. Availability includes alligator, calf, canvas NATO and vulcanized rubber, all made to artisanal standards. For a bespoke experience, the Casati Milano atelier creates made-to-measure straps with personal leather selection, real-time updates and 18-month warranty.

A high-quality leather strap (alligator, calf, shell cordovan) lasts an average of 3-5 years with moderate daily use, provided regular maintenance: protection from excess moisture, monthly cleaning with a soft cloth, and conditioning with natural wax every 6 months. Vegetable-tanned alligator develops a protective patina over time, extending functionality. Strap breakage is almost always limited to the crease area (lug), replaceable by specialist craftsmen, making investment in noble leathers economical in the long term.
