Frequently asked questions
What is the exact lug width of the Longines Elegant L4.309.5.89.7?
The lug width of the Longines Elegant L4.309.5.89.7 is 13mm. This dimension is calibrated for the 25.50mm case diameter and represents the ideal proportional relationship between the case size and the strap width that surrounds the wrist. Measurement must be taken from lug to lug, which is the distance between the two lateral lugs where the strap is seated.
Which strap material best complements the Longines Elegant L4.309.5.89.7?
Alligator is the noblest choice, featuring a refined grain structure that develops a magnificent patina over time. Vegetable-tanned calf leather offers an aesthetic-practical compromise, maintaining elegance whilst acquiring textured character. For versatility, a NATO strap in dark grey or navy wool provides surprising sophistication, whilst FKM rubber delivers sporty yet refined solutions ideal for summer wear.
How do I change the strap on the Longines Elegant L4.309.5.89.7?
Straps are changed using a dedicated spring bar tool. Position the watch with the strap facing downwards on a soft surface, locate the spring bars that secure the strap to the lugs, gently lever them with the tool until they release, then remove the old strap. Align the spring bars of the new strap with the lug seats and apply gentle pressure until they click into place. This is a delicate operation: if uncertain, entrust the task to Casati Milano atelier.
Can I use an aftermarket 13mm strap on this Longines?
Yes, any strap with a 13mm lug width is compatible. Milano Straps offers a complete range of 13mm straps in alligator, calf, rubber and fabric, customisable in length, initials and thread colour. It is essential to verify that the total length is suitable for your wrist: measure your original strap and compare with the specifications of the new one before purchase.
How long does a leather strap last on a Longines Elegant?
A quality leather strap (alligator or calf) typically lasts 2-4 years with moderate use, longer if worn for specific occasions. Longevity depends on frequency of wear, moisture exposure and maintenance. Alligator generally outlasts calf leather. Casati Milano provides an 18-month warranty on all handmade straps, covering manufacturing defects and premature anomalous wear.
