Strap for Flagship 35.6 Automatic Stainless Steel Silver

The lug width of the Longines Flagship L4.774.4.72.2 is 18 mm. This width is specific to this 35.60 mm case model and has been engineered to maintain correct visual proportions. To verify, remove the strap and measure the space between the two lugs at the case extremities.

For the Flagship L4.774.4.72.2, we recommend alligator with vegetable tanning (light tobacco or platinum grey), which dialogues elegantly with the case's satin-finished steel. Equivalent quality alternatives include Italian calf in bordeaux or shell cordovan in mahogany tone. For sportier wear, vulcanised rubber in black or military canvas maintains the model's sober character.

To change the strap, you will need a spring bar tool. Position the watch on a flat surface, gently compress the spring within the lug hole using the tool, remove the pin, then slide out the old strap. Insert the new strap (ensuring it is exactly 18 mm wide) and reintroduce the pins into the case lugs until they click securely into place.

Yes, provided the lug width is exactly 18 mm. Many aftermarket straps are available in 20 mm, 22 mm or 24 mm widths, so always verify specifications. On milanostraps.it you will find 18 mm artisan straps compatible and customisable. If in doubt, the Casati Milano atelier can advise you on the best solution.

Leather strap longevity depends on usage and tanning quality. An alligator or calf strap with vegetable tanning, worn daily, maintains structural integrity for 3–5 years. Shell cordovan tends to last longer due to greater fibre density. The Casati Milano atelier guarantees 18 months on bespoke straps, and the strap can be regenerated (replacing the pin and buckle) to extend its lifespan.
