Frequently asked questions

What is the lug width of the Longines Master Collection L2.717.8.78.3?

The lug width of the L2.717.8.78.3 is 20mm. This measurement represents the effective space between the spring bar holes on the case and allows the use of 20mm-compatible straps from various artisanal and industrial manufacturers.

Which strap do you recommend for the Longines Master Collection L2.717.8.78.3?

For the L2.717.8.78.3, we recommend a medium-dark brown or cognac alligator strap, which enhances the natural warmth of the 18k rose gold case. Shell cordovan represents a durable alternative for those seeking a more compact texture. A vegetable-tanned calf in mouse grey offers restrained modernity for contemporary contexts.

How do I change the strap on the Longines Master Collection L2.717.8.78.3?

The strap is removed by gently unscrewing the spring bars at the case ends using a dedicated tool (spring bar tool). Position the tool in the bar's groove to compress the internal spring, then extract the pin from its seat. Identical procedure in reverse order for installing the new strap. If inexperienced, consult a professional.

Is an aftermarket strap compatible with the L2.717.8.78.3?

Yes, any strap with a 20mm lug width is compatible with the L2.717.8.78.3, whether produced by specialised manufacturers or standard producers. Compatibility depends exclusively on lug width and not on the watch brand.

How long does an artisanal leather strap last on the Longines L2.717.8.78.3?

An alligator or calf strap of artisanal quality, with proper maintenance (regular cleaning, controlled humidity exposure), maintains functionality and aesthetics for 3-5 years of daily use. Shell cordovan, thanks to its natural density, can extend durability to 7-8 years. The natural patina that develops over time adds aesthetic value to the strap.
