Strap for Master Collection 38.5mm Power Reserve Stainless Steel / Black-Roman / Alligator

The lug width of the Longines Master Collection L2.708.4.51.5 is 20mm. This measurement represents the internal space between the two lugs of the case where the strap attaches. Accurate measurement is essential to avoid purchasing incompatible straps. All 20mm straps in our catalogue are fully compatible with this model.

For the Master Collection L2.708.4.51.5, we recommend high-quality alligator leather with natural patina in brown or black tones, which enhances the watch's discreet elegance. Shell cordovan is excellent for those desiring a lustre that evolves with wear. Vegetable-tanned calf leather provides immediate comfort and chromatic versatility. We advise against synthetic materials that compromise the watch's construction quality.

The strap is changed using a spring bar removal tool or small lever. Position the tool under the pin securing the strap to the case, apply gentle pressure to compress the internal spring, and slide the pin out of its housing. Repeat on the opposite lug. Insert the new 20mm strap by sliding the pin through the housings until you hear the locking click.

Yes, any high-quality 20mm strap is compatible with the Longines Master Collection L2.708.4.51.5. Milano Straps' aftermarket straps, crafted in alligator, calf leather, or shell cordovan, guarantee construction quality comparable to or exceeding original Longines straps. Casati Milano atelier also offers bespoke customisations with hand-selected leathers.

A quality leather strap on a Longines Master Collection L2.708.4.51.5 typically lasts 2 to 4 years with daily use and proper maintenance. Alligator and shell cordovan tend to last longer whilst developing patina. Vegetable-tanned calf requires occasional conditioning with natural oils. Proper storage away from extreme humidity and heat significantly extends the strap's lifespan.
