Strap for Elegant Collection Automatic 39 Stainless Steel / Silver/ Bracelet

The lug width is 20 mm. This is the distance between the lugs where the strap attaches to the case. It is essential to verify this measurement before purchasing an aftermarket strap to ensure perfect compatibility.

We recommend straps in brown or black alligator, vegetable-tanned calf leather, or NATO fabric in cotton-linen for versatility. Alligator with fine grain maintains the sober and technical aesthetic of the case, whilst aged calf develops a fascinating patina over time.

Remove the strap using a dedicated spring bar tool to extract the pins from the lugs. Insert the pins into the new strap by aligning the holes, then reinsert the pins into the case seats. Verify that the pins are firmly positioned. If you are unfamiliar with the operation, consult a professional watchmaker.

Yes, the Longines Elegant L4.910.4.77.6 is fully compatible with professional-quality aftermarket straps in 20 mm size. Ensure the strap has a width of at least 20 mm and that the pins are of the correct dimension for secure insertion.

A quality leather strap (alligator or vegetable-tanned calf) has an average lifespan of 3-5 years with daily use, provided proper maintenance: avoid prolonged contact with water, sweat and chemical agents, clean regularly with a soft cloth and periodically nourish the leather with specific protective creams.
