Strap for Master Collection 38.5 Day Date Pink Gold / Silver-Arabic / Alligator

The lug width of the Longines Master Collection L2.755.8.78.3 is 20 mm. This dimension, measured between the two internal attachment points of the strap to the case, defines the exact width of the compatible strap. A caliper or flexible ruler allows for precise measurement without error.

For a rose gold watch like the L2.755.8.78.3, alligator or shell cordovan represent the ideal choices. Alligator maintains a fine grain that pairs naturally with the warmth of rose gold, whilst shell cordovan develops a fascinating reddish-brown patina over time. A vegetable tanned leather in cognac tones offers daily versatility whilst maintaining structural elegance.

The strap is changed by extracting the attachment pins at the lugs using a dedicated tool (spring bar tool). Insert the flat tip of the tool into the small groove beside the pin, apply gentle pressure to compress the internal spring and extract the pin. Repeat the procedure on both sides. Insert the new strap by reversing the process, ensuring that the pin clicks into position securely.

Yes, the L2.755.8.78.3 is fully compatible with any 20mm aftermarket strap. At milanostraps.it you will find a wide selection of straps in fine leather, alligator, shell cordovan and specialised fabrics, all suitable for this lug width with the possibility of customisation (length, initials, thread colour).

The lifespan of a leather strap depends on the quality of the leather and the frequency of use. A high-quality alligator or shell cordovan strap can last 3–5 years with regular daily wear, if maintained and protected from excessive moisture and heat. Vegetable tanned leather has a slightly shorter lifespan, approximately 2–4 years, but develops a fascinating patina that increases aesthetic value over time. The Casati Milano 18-month warranty covers manufacturing defects and materials.
