Strap for Master Collection Big Date Small Seconds

The lug width of the Longines Master Collection L2.676.4.78.6 is 21mm. This dimension requires specifically designed 21mm watch straps to avoid visible gaps or forcing at the case lugs. It is a less common standard compared to 20 or 22mm, so compatibility must be verified before purchase.

For the Master Collection L2.676.4.78.6, we recommend black or brown alligator for formal wear, shell cordovan for developing patina, or vegetable-tanned calf leather for daily versatility. Choice depends on use: formal occasions prefer black alligator, smart-casual favour medium brown, intensive daily wear requires robust calf.

The Master Collection L2.676.4.78.6 strap is changed by removing the spring bars (or lugs): insert a flat, thin tool (dedicated spring bar tool or tweezers), push towards the centre to release tension, and extract the pin. Align the new strap with the lugs and verify the pin clicks into position. If inexperienced, consult a watchmaker.

Yes, many aftermarket straps are compatible with the 21mm lug width. milanostraps.it offers artisanal straps in various leathers (alligator, shell cordovan, calf) and finishes ready to ship or customisable. The Casati Milano atelier creates bespoke custom straps for your Master Collection L2.676.4.78.6.

Durability depends on material and usage. Alligator and vegetable-tanned calf last 3–5 years with moderate daily wear. Shell cordovan, if well maintained, exceeds 5 years thanks to robust fibre. Critical factors: ambient humidity, body perspiration, sun exposure, maintenance (monthly cleaning, bi-annual nourishment with specific balm).
