Frequently asked questions
What is the lug width of the Longines Presence L4.321.2.15.8?
The lug width of the Longines Presence L4.321.2.15.8 is 13mm. This measurement refers to the distance between the pins that support the lugs in the case. To verify it, use a digital calliper positioned perpendicularly between the two pins; you should read exactly 13mm. This dimension falls outside universal standards and requires straps specifically cut for this width.
What is the best strap for the Longines Presence L4.321.2.15.8?
The best strap depends on intended use. For absolute formality, we recommend black or dark brown alligator with satin finish. For elegant daily wear, vegetable-tanned calf offers the best balance between natural patina development and durability. For those seeking practicality, a thick rubber strap or NATO maintains proportions without requiring maintenance. The essential factor is that it be cut for 13mm lug width.
How do you change the strap on the Longines Presence L4.321.2.15.8?
Strap replacement involves removing the pins that pass through the lugs. Position the watch on a soft mat with the lugs facing upwards. Using a dedicated tool (spring bar tool), compress the small internal metal hook of one pin to release it from its housing, then extract it gently. Repeat on the other side. Insert the new pins into the 13mm strap and reinsert into the watch, ensuring they are fully inserted and locked.
Is the Longines Presence L4.321.2.15.8 compatible with aftermarket straps?
Yes, it is compatible with aftermarket straps, but exclusively with models cut for a 13mm lug width. Generic or universal straps will not fit correctly to this measurement. At milanostraps.it you will find a complete selection of artisanal straps specifically made for 13mm, with options in alligator, calf, shell cordovan, rubber and textile materials.
How long does a leather strap last on the Longines Presence L4.321.2.15.8?
The lifespan of a leather strap depends on the tanning method, usage, and maintenance. A quality alligator strap has an average lifespan of 3-5 years with moderate daily use. Vegetable-tanned calf typically lasts 2-4 years but develops pleasant patina over time. Rubber is more durable (5-7 years) but is affected by UV rays. Regular maintenance (protection from moisture, quick drying after perspiration, rotation with other straps) significantly extends lifespan. The Casati Milano atelier provides an 18-month guarantee on all bespoke straps.
