Frequently asked questions

What is the lug width of the Longines Heritage L2.195.4.53.6?

The Longines Heritage L2.195.4.53.6 features a 10mm lug width, a specialised dimension requiring purposefully constructed straps. This width was deliberately chosen to maintain the proportional balance of the 15.90mm case diameter, preventing the strap from visually overwhelming the watch.

Which strap is recommended for the Longines L2.195.4.53.6?

For this miniaturist proportioned model, alligator with vegetable tanning represents the quintessential choice: the natural grain of the leather does not visually burden the watch and develops an extraordinary patina over years. Alternatively, calf leather or technical straps in high-density rubber offer versatility whilst maintaining proportional elegance.

How do I change the strap on the Longines Heritage L2.195.4.53.6?

Strap change occurs through the 10mm lug attachments. Using a dedicated spring bar tool, one removes the elastic bar from the lug, freeing the old strap and allowing insertion of the new one. The operation requires care to avoid damaging the case; alternatively, Casati Milano atelier performs the service with guarantee.

Can I fit an aftermarket 10mm strap on my Longines Heritage?

Yes, provided the strap is constructed for 10mm lugs. The artisanal straps available on milanostraps.it are compatible with this specification; it is essential to verify that the lugs are correctly dimensioned to ensure secure attachment without stressing the case.

How long does a leather strap last on the Longines L2.195.4.53.6?

A quality natural leather strap, with regular maintenance, lasts between 3 to 7 years depending on use and tanning method. A vegetable-tanned strap ages gracefully, developing a patina that mirrors the watch's history. The 18-month guarantee offered by Casati Milano covers manufacturing and finish defects.
