Strap for DolceVita 20 Quartz Stainless Steel Diamond Roman

The lug width of the Longines DolceVita L5.155.0.71.6 is 15mm. This unconventional measurement reflects the harmonious proportions of the rectangular case. To verify, measure the distance between the outer edges of the lugs with a digital calliper; you will find exactly 15mm. This specific geometry requires straps designed precisely for this width.

Alligator leather represents the most sophisticated choice thanks to its regular grain and luminous texture that enhances the rectangular design. For a patina that develops over time, vegetable-tanned calf offers authentic character. Shell cordovan is ideal for those seeking natural compactness and deep lustre. Your choice should depend on the environment: delicate straps for controlled settings, robust materials for intensive daily wear.

Changing the strap requires extraction of the case's lateral pins. Use a dedicated tool (spring bar removal tool) to push the pin from one side to the other, supporting the case gently to prevent scratches. Once the pin is extracted, the old strap releases and you can insert the new one by aligning it with the lugs. Reinsert the pin with fluid movements until you feel the locking click. If uncertain, consult a specialist watchmaker.

Absolutely. 15mm aftermarket straps are fully compatible with the DolceVita. Online retailers offer selections of straps ready for dispatch, customisable in length, initials and stitching thread. For a personalised experience, the Casati Milano atelier creates bespoke straps with direct choice of leather, WhatsApp updates and 18-month warranty. Compatibility is total provided the lug width is exactly 15mm.

A quality leather strap has an average lifespan of 3 to 5 years of daily use, varying based on material and environmental conditions. Alligator and shell cordovan are more resistant to wear than calf, offering superior longevity. Prolonged exposure to sunlight, moisture and mechanical wear accelerate ageing. A vegetable-tanned calf strap develops patina over time, visible as a natural sign of use. To extend lifespan, alternate straps and allow them to rest between uses.
