Strap for DolceVita 23 Quartz Stainless Steel / MOP

The Longines DolceVita L5.512.4.87.2 features a non-standard 17mm lug width, reflecting the vintage-inspired proportions of its 23mm rectangular case. This dimension is characteristic of this generation of DolceVita timepieces. To verify the measurement accurately, use a digital calliper to measure the internal distance between the two metal lugs where the strap attaches.

The ideal material depends on usage and aesthetic preference. For pure elegance, alligator leather in Havana or cognac brown amplifies the Art Déco character of the case. European calf in vegetable tanning offers evolving patina and authenticity; shell cordovan provides maximum durability with an oiled effect. For daily versatility, vegetable-tanned calf in dark chocolate with silk thread stitching creates aesthetic balance without competing with the timepiece.

The 17mm bayonet lugs require a dedicated spring bar tool. Position the watch on a soft surface (microfibre cloth), insert the tool tip into the lug release hole, push inward to reduce spring tension, then gently remove the old strap. Install the new strap by reversing this procedure. Casati Milano recommends requesting a pre-sample to verify measurements before final strap production.

No. The 17mm lug width does not correspond to modern standards (18mm, 19mm, 20mm), making common aftermarket straps incompatible. You must source straps specifically sized at 17mm from specialist retailers such as Milano Straps or the Casati Milano atelier, which manufactures custom straps tailored to your watch's precise requirements.

Longevity varies according to material and wear patterns. European calf in vegetable tanning lasts 3-5 years with daily use; shell cordovan reaches 7-10 years thanks to superior fibre-structural density; alligator offers 4-6 years. Critical factors include UV exposure (degrades tannins), ambient humidity, and skin transpiration. Casati Milano provides an 18-month warranty on custom-made straps, with regeneration options for aged leather through technical updates.
