Frequently asked questions

What is the lug width of the Longines Flagship L4.274.4.72.6?

The Longines Flagship L4.274.4.72.6 has a lug width of 18mm. This is the distance between the two metal spring bars that attach the strap to the case. It is essential to measure correctly before purchasing an aftermarket strap to ensure perfect compatibility.

Which strap is recommended for the Longines Flagship L4.274.4.72.6?

For this classic model, a vegetable-tanned leather strap is recommended, preferably in alligator or calf. Alligator with natural patina amplifies the vintage character of the watch, whilst calf ensures a more formal appearance. For casual use, a NATO in repp fabric or a shell cordovan offer refined alternatives.

How do you change the strap on the Longines Flagship L4.274.4.72.6?

The strap is changed by removing the spring bars with a dedicated tool (spring bar remover). Insert the small lever under the bar from the top of the lug, press gently to release the spring, and extract the bar. Repeat on the other side. To mount the new strap, align the holes and reinsert the bars until they click into place.

Is it possible to use an aftermarket strap on this Longines?

Yes, any strap with an 18mm lug width is compatible with the Longines Flagship L4.274.4.72.6. Artisanal Milanese straps offer superior quality to the original strap, with a choice of premium leathers, personalised stitching threads, and bespoke finishes that enhance the watch's classic nature.

How long does a leather strap last on this watch?

A quality artisanal leather strap, with vegetable tanning and crafted using traditional techniques, typically lasts 5-10 years with daily use. Durability depends on the tanning method, leather type (alligator resists longer than calf), mechanical wear, and maintenance. The standard warranty is 18 months; with care, the strap will age beautifully, developing a distinctive patina.
