Frequently asked questions

What is the lug width of the Longines Presence L4.277.6.12.6?

The lug width is 12mm. Measure it by positioning a digital calliper perpendicularly between the two case lugs, measuring from the centre of one lug to the centre of the other. This is a precise dimension and requires a strap specifically crafted for this size.

What is the best strap for the Longines Presence L4.277.6.12.6?

Genuine alligator is the most refined choice: its natural texture mirrors the elegance of the yellow gold case. Calf leather with crocodile grain offers practicality and durability, while shell cordovan delivers deep patina development. For summer, a neutral rubber or NATO canvas strap maintains sophistication without sacrificing comfort.

How do I change the strap on my Longines Presence?

Use a spring bar tool to extract the lugs from the case. Position the tool in the groove adjacent to each lug, apply gentle pressure and the lug will retract. Remove the old strap and insert the new one by aligning the eylets to the case lugs. The procedure is straightforward but requires care to avoid damaging the case.

Are aftermarket straps compatible with the Longines Presence L4.277.6.12.6 available?

Yes. Milano Straps offers a complete collection of aftermarket straps in 12mm, customisable in size, initials and stitching thread. They ship ready for installation. For a fully personalised experience, the Casati Milano atelier creates bespoke straps with direct selection of leathers.

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

A high-quality leather strap, with vegetable tanning or genuine alligator, lasts 3 to 5 years with proper maintenance. Deterioration depends on humidity and UV exposure. A well-maintained shell cordovan or alligator strap develops patina over time, increasing its aesthetic value. Casati Milano offers an 18-month warranty and post-purchase maintenance services.
