Strap for Master Collection 44 Retrograde Power Reserve Pink Gold / Silver-Arabic / Alligator

The lug width (distance between the two lugs) of the Longines Master Collection L2.716.8.78.3 is 20mm. This measurement is the internal span between the spring bar attachment points on the case. To verify, position a calliper or ruler on the watch lugs with the watch strap removed. Accurate measurement is essential when ordering a compatible aftermarket strap.

For the Master Collection in rose gold, an alligator strap in dark brown or cognac is recommended, as it complements the warm tone of the case without jarring contrast. Alternatively, shell cordovan in deep burgundy develops an elegant patina and ages visibly. For everyday versatility, vegetable-tanned calf in grey pearl or beige provides colour neutrality, while a heavyweight cotton NATO in navy blue permits sportive versatility whilst maintaining formal character.

To change the strap on a Longines, use a spring bar removal tool. Insert the flat end of the tool into the hole on the inner side of the lug attachment, press gently to release the internal spring, and slide the tool laterally to extract the strap. Repeat on the opposite side. Insert the new strap by aligning the holes with the lugs and pressing firmly until the spring mechanism clicks into place. If uncertain, consult a specialised watchmaking service.

Yes, any strap with a 20mm lug width is compatible with the Master Collection L2.716.8.78.3. It is essential to verify that the internal measurement between the lugs is precisely 20mm. Artisanal straps of quality allow personalisation in leather (alligator, shell cordovan, calf), length, and stitching thread, adapting perfectly to the case proportions.

The lifespan of a leather strap depends on the material and usage. An artisanal strap in alligator or shell cordovan of quality, with ordinary care (protection from excessive moisture, regular drying), lasts between 3 and 6 years. A vegetable-tanned calf strap has similar longevity but ages visibly, developing patina. Daily wear on a regularly-worn watch accelerates wear. Constant exposure to water, perspiration, and humidity significantly shortens useful life. Professional artisanal strap warranties typically extend to 18 months.
