Strap for Flagship 35.6 Automatic Pink Gold

The lug width of the Longines Flagship L4.774.8.27.2 is 18mm. This dimension represents the distance between the pins that connect the strap to the case. To verify it, measure the internal space between the two lugs perpendicularly with a digital calliper. It is essential to know this exact measurement to select compatible straps.

For this classical rose gold timepiece, we recommend Mississippi alligator in Havana brown, Taurillon calf in bordeaux tones, or natural colour shell cordovan. Alligator is the most stylistically coherent choice, maintaining sobriety and elegance. Shell cordovan is ideal if you appreciate the evolution of patina over time. Avoid materials with pronounced texture that would disrupt the classical harmony of the model.

Remove the watch from your wrist. Using a spring bar tool, insert the flat end into the lateral opening of the bar, pressing gently downward to release the tension. The bar will retract and you can extract the strap. Repeat on the other side. To install the new strap, align the extremities with the pins, then push the bar until it clicks into place on both sides.

Absolutely. Custom aftermarket straps, crafted by specialised artisans, fit perfectly to the 18mm width of the Flagship. Ensure that the strap features correct internal diameters for the pins (standard 1.5mm) and that the lugs are positioned symmetrically relative to the strap body. High-quality straps present no risk to the case.

Durability depends on leather quality, frequency of wear, and environmental conditions. High-quality alligator Mississippi or shell cordovan maintains structural integrity for 3-5 years with daily use, developing a desirable patina. Vegetable-tanned calf has similar longevity. The most wear-prone component is the keeper (passante), which supports the strap around the wrist: elasticity loss after 2-3 years is normal. However, straps with reinforced keepers or enhanced buckles significantly extend useful life.
