Frequently asked questions

What is the lug width of the Longines Presence L4.321.2.42.7?

The lug width is 13mm. This measurement is specific to the feminine 25.50mm case and is essential for purchasing a compatible strap. To verify the measurement, place a digital calliper between the two horizontal lugs protruding from the case at the midpoint, without applying pressure.

Which strap material is recommended for the Longines Presence L4.321.2.42.7?

Alligator in natural tones (cognac brown or black) is ideal for highlighting the formal elegance of the Presence. Vegetable-tanned calf leather is a contemporary choice that develops aging patina over time. Baader or Tropic rubber is perfect for swimming or water sports whilst maintaining elegant styling. Shell cordovan offers discrete luxury and chromatic versatility.

How do you change the strap on the Longines Presence L4.321.2.42.7?

Remove the original strap by extracting the two horizontal spring bars with a specialised tool (spring bar remover). Insert the new strap by sliding the bars into the case lugs, ensuring the strap is centred and the bars are fully seated. This operation is straightforward and takes only seconds. If unsure, consult a jeweller or specialised atelier.

Is there an aftermarket strap compatible with the Longines Presence L4.321.2.42.7?

Yes, Milano Straps offers a complete range of 13mm straps ready for shipment, customisable in sizes, initials and stitch colour. All straps are crafted from premium leather (alligator, calf, shell cordovan, rubber) and are certified compatible with the Presence. Casati Milano atelier also creates bespoke straps with an 18-month guarantee.

What is the lifespan of a leather strap for the Longines Presence L4.321.2.42.7?

A premium quality leather strap (alligator, calf, shell cordovan) typically lasts 3-5 years with daily use, developing an aging patina that increases aesthetic value over time. Lifespan depends on humidity, frequency of water contact and mechanical wear of the keeper. A Baader rubber strap lasts 5-7 years and is moisture-resistant. Regular maintenance (cleaning and conditioning) significantly extends lifespan.
