Strap for Master Collection Date 25.5 Stainless Steel - Pink Gold / Black / Bracelet

The Longines Master Collection L2.128.5.59.7 features a lug width of 13mm, measured from the inner edge of one attachment point to the inner edge of the opposite point. This is a non-standard dimension requiring careful strap selection. To verify accurately, use a digital calliper or ruler positioned perpendicular to the watch's longitudinal axis.

For the Longines Master Collection L2.128.5.59.7, alligator leather in chocolate or cognac tones complements the interplay between rose gold and stainless steel. Vegetable-tanned calf in burgundy or moss green offers daily versatility with a patina that evolves over time. Shell cordovan represents an elegant middle ground with natural lustre. For light sports applications, FKM rubber maintains the collection's classic identity whilst ensuring durability.

Replacing the strap on a luxury timepiece such as a Longines requires specialised tools: a spring bar removal tool and a flat work surface. Position the watch on a soft cushion, locate the small lateral aperture on the lug, insert the tool with gentle pressure to release the retaining spring, extract the bar carefully, and attach the new strap. If you lack the appropriate tool, consult a professional watchmaker or authorised dealer to prevent movement damage.

Yes, with informed selection. Since the lug width measures 13mm, source straps dimensioned specifically for this width. A 14mm strap forces the lug and compromises attachment security; a 12mm strap creates dangerous play. Milano Straps' bespoke leather straps in alligator, calf, and shell cordovan are engineered for this dimension and offer 18-month warranty assurance.

Strap longevity depends on leather grade, usage frequency, and environmental exposure. Premium alligator leather with vegetable tanning typically lasts 2–3 years under moderate daily wear. Shell cordovan, owing to its fibrous structure, endures 4–5 years. FKM rubber extends to 5–6 years. Prolong lifespan by minimising water and humidity exposure, applying hydrophobic treatment every six months, and storing the strap in a climate-controlled environment when unused.
