Strap for Presence 33 Quartz Yellow

The lug width of the Longines Presence L4.720.2.12.8 is 18.00 mm. This measurement is the distance between the inner shoulders of the lugs, where the strap connects to the case. It is a non-standard dimension in the dress watch segment, requiring precision when selecting an aftermarket strap.

For the Presence, we recommend an alligator strap with satin finishing for formal occasions, or vegetable-tanned calf leather for more versatile daily wear. FKM rubber is ideal for humid environments without sacrificing elegance. A NATO strap in robust fabric remains an informal yet refined option. In all cases, ensure the lug width is exactly 18 mm.

The Longines Presence features straight lugs with standard spring bars. To change the strap: remove the metal rod (spring bar) that passes through the lug using a dedicated tool (spring bar tool). Extract the old strap laterally. Insert the ends of the spring mechanism into the new strap, then reinsert the rod into the case lugs, ensuring proper engagement. On newer models, check if the watch has a deployante buckle, which simplifies removal and attachment.

Yes, provided the lug width is exactly 18.00 mm. This means the width measured between the inner shoulders must match this dimension precisely. A bespoke artisanal strap ensures compliance with this tolerance without compromise. Avoid vague universal straps ("17–19 mm") that may cause unwanted play.

Durability depends on material, usage pattern and maintenance. A well-preserved alligator strap lasts 3–5 years with moderate daily wear. Calf leather, being more delicate, requires greater care and typically wears within 2–4 years. Natural FKM rubber is more durable (5–7 years) but less reversible. Vegetable-tanned leather develops patina over time, extending the visual lifespan. Store the strap in a dry environment and avoid prolonged sun exposure to slow ageing.
