DolceVita L5.155.4.73.6 (aka: L51554736)— lug 15mm

The lug width of the Longines DolceVita L5.155.4.73.6 is 15 mm. This dimension is model-specific and was engineered to maintain the proportional balance of the rectangular Art Deco case. To measure correctly, place a calliper perpendicular to the lug, from lug to lug at the case base, excluding the crystal.

Alligator leather remains the most refined choice for the DolceVita, thanks to its fine grain and its patina development over time, which enhances the case's delicate proportions. Smooth or grain calf leather offers a balanced solution between elegance and daily practicality. Fine-textured rubber provides contemporary versatility without contradicting the model's heritage.

To change the strap on a watch with 15mm lugs, place the watch on a soft cloth. Use a dedicated tool (spring bar tool or removal device) to gently push the lug pins inward, freeing the old strap. Insert the new strap by sliding the pin back into position, ensuring it is fully locked.

Yes, provided the strap is specifically crafted for a 15mm lug width. Artisanal straps of superior quality, such as those from Milano Straps, are customisable in leather, colour and details (initials, stitching thread). We always recommend premium aftermarket straps over generic brands.

A superior-quality leather strap (alligator, calf, shell cordovan) typically lasts 4–6 years with moderate daily use. Durability depends on wearing frequency, humidity exposure and care. Vegetable-tanned leather straps develop an elegant patina, improving in appearance over time. Milano Straps offers an 18-month guarantee and restoration services.
