FAQ
What is the lug width of the Longines Master Collection L2.773.4.71.6?
The lug width of the Longines Master Collection L2.773.4.71.6 is 21mm. This measurement represents the distance between the two spring bars that attach the strap to the watch case. It is essential to verify this parameter before purchasing an aftermarket strap, as even a minor variation would result in mechanical incompatibility.
Which strap should I choose for the Longines Master Collection L2.773.4.71.6?
For the Longines Master Collection L2.773.4.71.6, we recommend dark brown alligator for formal occasions, grey or blue calf leather for everyday versatility, or burgundy shell cordovan for those seeking artisanal authenticity. Your choice should depend on the dial colour and intended use. A vegetable-tanned leather strap develops a unique patina over time.
How do I change the strap on my Longines Master Collection L2.773.4.71.6?
Changing the strap is straightforward if your watch features a deployant clasp. If the strap is secured with traditional spring bars, you will need a dedicated removal tool to extract the pins. We recommend consulting a professional for the first change to avoid scratching the case.
Which aftermarket straps are compatible with the 21mm lug width of the L2.773.4.71.6?
Any strap with a 21mm lug width is compatible with your L2.773.4.71.6. You will find options in alligator, calf leather, cordovan, vegetable-tanned leather, rubber, and NATO fabric. Always verify that the declared width is precisely 21mm and that the strap is manufactured to specifications matching your case profile.
How long does a leather strap last on the Longines Master Collection L2.773.4.71.6?
Strap longevity depends on material and daily use. A quality alligator or cordovan can last 3–5 years with routine care (avoid direct water exposure, limit sun exposure, treat with specialised balm annually). Calf leather may require replacement after 2–3 years due to its greater delicacy. Vegetable-tanned leather ages naturally without degradation, offering greater longevity if you appreciate its aesthetic evolution.
