FAQ
What is the lug width of the Longines Master Collection L2.893.4.77.6?
The lug width of the Longines Master Collection L2.893.4.77.6 is 21.00mm. This dimension requires specific straps: a 20mm strap would be loose, whilst a 22mm strap would not fit. Correct measurement is carried out with a digital calliper, measuring the internal distance between the two lugs of the case.
What is the best strap for the Longines Master Collection L2.893.4.77.6?
For the Master Collection L2.893.4.77.6, we recommend black alligator or vegetable-tanned calf leather for formal elegance, or burgundy shell cordovan for important occasions. For daily versatility, cognac-coloured satin calf develops a fascinating patina over time. The choice depends on use and dial colour: dark blue requires black alligator, black allows burgundy shell cordovan or anthracite alligator.
How do I change the strap on the Longines Master Collection L2.893.4.77.6?
Strap changing requires a watchmaker's screwdriver and gentle downward pressure on the internal locking pin within the lug. Insert the pin into the hole, press until the strap slides away, then extract the pin. The reverse process installs the new strap: position the pin in the new lug's hole and press until the click of engagement.
Is a 21mm aftermarket strap compatible with the Longines Master Collection L2.893.4.77.6?
Yes, any artisanal strap with a 21.00mm lug width is compatible. It is important to verify that manufacturing tolerances are rigorous (±0.2mm maximum) and that the strap presents no burrs. The milanostraps.it straps for 21mm are quality-controlled in production and guaranteed for 18 months, with the possibility of personalising initials and stitching thread.
How long does a leather strap last on the Longines Master Collection L2.893.4.77.6?
Durability depends on material and usage. Alligator and shell cordovan in vegetable tanning resist 4-6 years with daily wear; calf leather, being softer, lasts 3-4 years. Degradation factors: sunlight exposure, perspiration, humidity and frequency of wear. Regular maintenance (gentle cleaning, humidity protection) prolongs life. Casati Milano offers 18 months' guarantee and reconditioning services.
