Frequently asked questions

What is the lug width of the Longines Présence L4.321.2.15.7?

The lug width of the Longines Présence L4.321.2.15.7 is 13mm. This is a specific <a href="https://milanostraps.it/collections/cinturini-orologi-per-misura-ansa-13mm">lug width</a> for reduced case diameters (25.5mm), consistent with the dress watch aesthetic of the series. To verify the measurement with precision, use a digital calliper inserted into the space between the two lateral lugs at the crown level.

What is the best strap for the Longines Présence L4.321.2.15.7?

The best strap for the Longines Présence L4.321.2.15.7 depends on intended use. For formal contexts, we recommend <a href="https://milanostraps.it/collections/cinturini-orologi-per-misura-ansa-13mm">alligator</a> in cognac or black with <a href="https://milanostraps.it/collections/cinturini-orologi-per-misura-ansa-13mm">vegetable tanning</a>. For everyday elegance, Italian aniline calf in grey or dark brown. For versatile casual wear, a NATO in cotton navy blue maintains aesthetic coherence. Black rubber functions well for discrete sporty combinations.

How do you change the strap on the Longines Présence L4.321.2.15.7?

The strap on the Longines Présence is changed by extracting the spring bars that fix the lugs to the case. Use a spring bar tool to push the pin downward and release the lug from the groove. Once both pins are extracted, the old strap detaches. Insert the new 13mm strap by aligning the lugs in the lateral holes and reinserting the pins. To ensure correct mounting and avoid damaging the delicate lugs, we recommend the Casati Milano service.

Is there an aftermarket strap compatible with the L4.321.2.15.7?

Yes, milanostraps.it offers an extensive catalogue of <a href="https://milanostraps.it/collections/cinturini-orologi-per-misura-ansa-13mm">compatible 13mm straps</a> ready for dispatch. All straps in that section have been tested for geometric compatibility with 25.5mm diameter cases. It is possible to customise length, colour, stitching and add initials. For a completely bespoke creation, the Casati Milano atelier crafts made-to-measure straps with personally selected leathers.

How long does a leather strap last on the Longines Présence?

A high-quality aniline leather strap, if subjected to regular wear, has an average lifespan of 3-5 years before requiring replacement. Durability varies based on intensity of use, climate conditions (humidity accelerates wear) and care standards. <a href="https://milanostraps.it/collections/cinturini-orologi-per-misura-ansa-13mm">Vegetable-tanned</a> leather develops patina over time, improving aesthetic appeal whilst remaining functional. Casati Milano straps include an 18-month guarantee against manufacturing defects. Replacement remains advisable when leather begins to show evident cracks or abnormal rigidity in bending.
