FAQ

What is the exact lug width of the Longines Master Collection L2.893.4.97.6?

The lug width of the Longines Master Collection L2.893.4.97.6 is precisely 21 millimetres. This measurement is taken between the two metal lugs on the case, centre to centre. It is a specific dimension that requires careful research in the aftermarket strap market, as it does not fall within the more common standards such as 20 or 22 millimetres. We recommend verifying with a digital calliper before ordering a replacement strap.

What is the best strap for the Longines Master Collection L2.893.4.97.6?

The best strap for this model depends on its intended use. For formal wear and supreme elegance, we recommend alligator in vegetable tanning with high-quality finishes, which develop patina over time. For versatile daily use, medium-grain calf leather offers superior comfort. Shell cordovan is ideal if you seek a structured and lustrous leather. A deployante clasp is strongly recommended to ensure comfort and security.

How do I change the strap on the Longines Master Collection L2.893.4.97.6?

Changing the strap on the Master Collection L2.893.4.97.6 is a straightforward operation. Using a spring bar removal tool, gently push the small spring towards the case whilst removing the metal pin from the first lug. Repeat the operation on the second pin. Insert the pins into the new strap, aligning them with the holes, then reinsert the pins into the case guides until you feel them click into place. Verify that both pins are firmly positioned before wearing the watch.

Can I use an aftermarket strap on a Longines Master Collection L2.893.4.97.6?

Yes, the Longines Master Collection L2.893.4.97.6 is perfectly compatible with quality aftermarket straps, provided they have the correct 21-millimetre lug width and standard-diameter pins. The Master Collection's pins are straight and uniform, facilitating fitting. We recommend selecting straps made from noble materials (alligator, calf, shell cordovan) to maintain the original quality standard of the watch.

How long does a leather strap last on a Longines Master Collection?

The lifespan of a leather strap for the Master Collection depends on the quality of the leather and its use. High-quality alligator or calf leather, with vegetable tanning, generally lasts 3–5 years of regular daily wear. Shell cordovan can last even longer thanks to its dense structure. The end-link area (subject to greater stress) is typically the first to fail. Regular maintenance and storage in a dry environment significantly extend the strap's life. An alternative is to rotate straps seasonally to distribute wear.
