Strap for Flagship 35.6 Quartz

The lug width of the Longines Flagship L4.716.4.12.6 is 18 millimetres. This specification is the standard for the Flagship model and allows the use of a wide range of aftermarket straps. To verify compatibility, measure the distance between the internal lug ends: it must be exactly 18 millimetres.

For the Flagship L4.716.4.12.6, premium leather straps are recommended: alligator in dark brown, black, or burgundy; vegetable-tanned calf in warm tones (cognac, tobacco); shell cordovan for those seeking a more distinctive character. These materials dialogue elegantly with the classic proportions of the case, enhancing its refined understatement.

The strap on the Flagship L4.716.4.12.6 is changed using a specialised tool (strap tool or lug remover) to extract the pins from the lugs. The pins must be removed with gentle transverse movement, without forcing to prevent damage to the stainless steel case. Once the old strap is removed, the new one (with 18mm lug width) is inserted by aligning the holes and pushing the pins until they seat fully. We recommend this operation be performed on a soft surface by someone with mechanical competence.

Yes, the Flagship L4.716.4.12.6 accepts compatible aftermarket straps with 18-millimetre lug width. Quality straps made from alligator, calf, shell cordovan, or fabric adapt perfectly to the case without modification. It is important to verify that the strap is specifically constructed for this lug width to ensure optimal fit and proportionate aesthetics.

The lifespan of a leather strap depends on material quality and intensity of use. A premium alligator or shell cordovan strap may last 3–5 years with ordinary maintenance and moderate wear. Vegetable-tanned calf, being more delicate, requires regular care and typically lasts 2–3 years before showing significant wear. Periodic replacement is part of the natural evolution of the watch, allowing aesthetic renewal without substantial investment.
