Strap for Master Collection Retrograde

The lug width (ansa measurement) of the Longines Master Collection L2.714.8.78.3 is 20 mm. This measurement refers to the distance between the two lugs of the case at its narrowest point, where the strap fits. Always measure correctly before ordering a replacement strap.

For a watch of this calibre, we recommend straps in dark brown or black alligator, which enhance the sophistication of the 18 carat rose gold case. Genuine alligator (with visible natural grain) represents the finest aesthetic and tactile choice. Shell cordovan and calf leather with vegetable tanning are also excellent options, provided they are of elevated craftsmanship.

The strap is changed by removing the spring bars that connect the strap to the case lugs. Use a specialist tool (spring bar tool) to compress the bar and extract it gently. Once the lugs are free, the old strap detaches. Insert the new strap by aligning the holes to the lugs and reinsert the bars until they click. We recommend seeking assistance from a watchmaker if you are not experienced with the procedure.

Yes, absolutely. The Longines Master Collection L2.714.8.78.3 is compatible with any strap with a 20 mm lug width. Artisanal aftermarket straps often offer greater personalisation, choice of noble materials and refined finishes compared to original options. Simply ensure that the strap has been crafted with the correct dimensions.

The lifespan of a leather strap depends on the quality of the material and the frequency of use. A high-quality artisanal strap in alligator or shell cordovan typically lasts 3-5 years with daily wear. Deterioration is influenced by water exposure, perspiration, sunlight and usage frequency. Proper maintenance (avoiding immersion, drying after moisture) significantly extends the life of the strap.
