Frequently asked questions

What is the lug width of the Longines Presence L4.321.2.42.8?

The lug width is exactly 13mm. This measurement is essential to ensure strap compatibility. Before ordering, measure the distance between the two pins protruding from the case at 12 o'clock and 6 o'clock: the value must be between 12.5 and 13.2mm to guarantee secure installation without damage to the case lugs.

Which strap is most suitable for the Longines Presence L4.321.2.42.8?

For the L4.321.2.42.8 we recommend alligator with vegetable tanning (fine grain, patina that evolves over time), English or French calf leather (formal without pretence), or NATO in satiny cotton for minimalist elegance. The choice depends on the use context and personal aesthetic preferences. Each material ages differently and imparts character to the timepiece over time.

How do you change the strap on the Longines Presence L4.321.2.42.8?

To change the strap you will need a spring bar tool and a stable surface. Position the watch at 12 o'clock facing you, locate the first pin with the tool, press laterally to compress the internal spring, and extract the pin from the case. Repeat for the second pin. Insert the pins into the new strap following the same procedure in reverse. Avoid excessive pressure on the case: the procedure should be smooth and fluid.

Is there an aftermarket strap compatible with this model?

Yes. Any strap with a 13mm lug width is compatible with the L4.321.2.42.8. On milanostraps.it you will find a complete collection of artisanal 13mm straps ready for dispatch, crafted with premium materials (alligator, calf, shell cordovan) and customizable in length, colour and stitching. For a bespoke experience, contact Casati Milano atelier for a custom creation with personal consultation.

How long does a leather strap last on a Longines Presence?

Durability depends on material, use and care. Quality alligator with vegetable tanning, worn regularly on an L4.321.2.42.8 at 25.5mm (reduced weight, lower lug stress), lasts 3 to 5 years of daily wear. Excellent calf leather lasts 2 to 3 years. Patina and wear marks are part of the beauty of natural leather. Casati Milano offers an 18-month warranty on all straps, with the possibility of refinishing and replacement of finishes after initial wear.
