Strap for Master Collection Retrograde

The lug width of the Longines Master Collection L2.715.8.78.3 is 20mm. This precise measurement indicates the internal distance between the attachment points of the spring bars on the case. To verify it, you must remove the current strap and measure with a digital calliper the distance between the fixing holes. A correct measurement is essential to ensure that the strap fits perfectly and that the spring bars remain securely anchored to the case.

For the Longines Master Collection L2.715.8.78.3 in rose gold, the most suitable strap is natural alligator in dark brown, mahogany brown or black. These choices maintain the formal elegance of the watch and create balanced optical proportions. Hand-crafted American alligator offers a refined surface and patina that improves over time. Alternatively, European shell cordovan creates exceptional chromatic effects and ages with character. For semi-formal contexts, a strap in vegetable-tanned leather in brown or black adds versatility whilst maintaining the nobility of the timepiece.

The strap of the Longines Master Collection L2.715.8.78.3 is changed using a specific tool to remove the spring bars. After locating the spring bars on the sides of the case, insert the tool into the small notch of the spring and push gently to release the pressure. Once the spring bar is removed from the hole, the old strap slides away. To install the new strap, position the lug in the upper hole, reinsert the spring bar making sure it seats correctly in the lower hole, and verify that it is firmly secured.

Yes, you can use an aftermarket strap of good quality as long as it is 20mm in lug width. Leather straps handcrafted by small manufactures often exceed the original strap in quality and personalisation. It is important to verify that the strap is equipped with stainless steel or brushed steel spring bars and that the stitching is double and regular. Straps in alligator, shell cordovan and vegetable-tanned leather offer a tactile and visual experience superior to standard straps, as well as a much more interesting ageing curve from an aesthetic point of view.

The durability of a leather strap depends on the quality of the leather and the intensity of use. A strap in natural alligator or quality shell cordovan lasts on average 3-5 years with daily use, developing a fascinating patina over time. A vegetable-tanned leather strap can last 2-4 years and visibly ages, creating character. The replacement frequency increases if the watch is worn in humid environments or if regularly exposed to water. To extend the life of the strap, it is advisable to avoid prolonged exposure to direct sunlight and occasionally apply a conditioner specific to fine leathers. A good artisanal strap can be reconditioned or regenerated by an experienced craftsman.
