Strap for Master Collection 44 Chronograph Pink Gold / Silver-Arabic / Alligator / 100th anniversary of the Republic of Portugal

The lug width (also known as lug distance or ansa) of the Longines Master Collection L2.740.8.73.3 is exactly 22 millimetres. This measurement represents the external distance between the two horizontal pins protruding from the case and is the critical specification for selecting compatible watch straps. A 22mm ansa ensures harmonious proportions with the 44mm case diameter, neither appearing excessively narrow nor disproportionately wide.

For the L2.740.8.73.3 model in pink gold, the most appropriate strap materials are: alligator leather in cognac or brown tones (the natural grain pattern dialogues with the warm luminosity of the precious metal), vegetable-tanned calf leather in bourbon or chocolate hues, and shell cordovan in mahogany (which develops a reddish patina similar to the aging characteristics of pink gold). We always recommend a pink gold deployant clasp matched to the case, never stainless steel, to maintain overall chromatic coherence.

Changing the strap on a Longines L2.740.8.73.3 requires two essential tools: a fine-tipped screwdriver and a spring bar removal tool (extractor). Position the watch face-down. Locate the two horizontal spring pins (one on each side), insert the extractor tool between the pin and the lug, apply gentle lateral pressure until the spring pin retracts into its spring-loaded housing. The old strap will now detach. Repeat on the opposite side. For the new strap, align the holes and reinsert the spring pins until they click into place, confirming secure retention.

Yes, any bespoke or artisanal watch strap featuring a 22 millimetre lug width is compatible with the Longines Master Collection L2.740.8.73.3. Compatibility depends exclusively on lug width specification, not on the watch brand. At milanostraps.it you will find a curated selection of 22mm straps in premium leathers—alligator, calf, shell cordovan, and rubber—all customisable regarding length, thickness, and stitching thread colour, with 18-month warranty coverage.

The lifespan of a natural leather strap varies depending on tanning method and actual usage patterns. A vegetable-tanned calf leather strap, worn daily under normal conditions, typically lasts 2–4 years before exhibiting significant wear. Shell cordovan, owing to its structural density, resists deterioration for 4–6 years or longer. Alligator leather offers intermediate durability of approximately 3–5 years. Variables including perspiration exposure, humidity levels, ultraviolet radiation, and preventive maintenance substantially influence longevity. Periodic conditioning with specialist leather creams extends the functional lifespan considerably.
