Strap for Presence 34.5 Automatic Stainless Steel Stick Bracelet

The lug width of the Longines Presence L4.721.4.18.6 is precisely 18 mm. This measurement is taken from the internal distance between the two sides of the case at lug height. To verify it correctly, use a digital calliper positioned perpendicular to the case shoulders.

The Presence pairs best with materials that respect its minimalist case aesthetic: dark brown or black alligator, vegetable-tanned calf in warm tones, or shell cordovan for those seeking durability and natural patina. A NATO strap in grey or navy canvas offers daily practicality, whilst technical rubber is ideal for humid or professional environments.

The Presence features standard 18 mm lugs. To change the strap, use a spring bar remover: insert the flat blade between the lug and existing strap, compress the internal spring of the lug, and slide out the old strap. Then insert the new strap until the spring clicks back into position. Never force the lugs.

Yes, any 18 mm compatible strap can be fitted to the Presence L4.721.4.18.6, as the case lugs conform to international standards. Always verify that the strap is certified for the correct width and that the end pieces align properly with the case geometry—lugs must be straight and perpendicular.

A high-quality natural leather strap, whether vegetable-tanned or alligator, typically lasts 3–5 years with daily wear, provided it receives regular air exposure and protection from excessive moisture. Shell cordovan lasts longer (5–7 years) due to natural fibre density. Periodic maintenance—conditioning with natural wax—significantly extends longevity.
