Strap for DolceVita 23 Quartz Stainless Steel / Diamond / MOP

The lug width of the Longines DolceVita L5.512.0.87.3 is 17 mm. This measurement determines strap compatibility: only straps with a 17 mm lug width will fit correctly, maintaining proper aesthetic proportions and mechanical security. Verify by measuring the space between the two lugs with a calliper.

For the DolceVita L5.512.0.87.3, an alligator strap with vegetable tanning in cognac or medium brown is recommended, as it complements the rectangular case's vintage-modern character. Alternatively, black or grey calf leather for formal occasions, or anthracite rubber for contemporary simplicity. Your choice depends on intended usage and the patina development you wish to achieve over time.

Remove the spring bars connecting the strap to the case using a spring bar tool. Position the tool in its seat, gently compress to release the internal spring, and slide the bar outward. Repeat for both sides. When installing the new 17 mm strap, ensure the spring bars are perfectly seated in the case cavities.

Yes, aftermarket straps with 17 mm lug width are fully compatible. However, verify stitching quality, leather type (alligator, calf, shell cordovan), and the presence of a robust deployante if applicable. Milanostraps.it offers artisanal straps in premium leather specifically compatible with this model, backed by an 18-month warranty if customised at Casati Milano atelier.

A high-quality leather strap (alligator or vegetable-tanned shell cordovan) typically lasts 3-5 years under daily use, developing natural patina. Longevity depends on usage frequency, climate conditions, and maintenance (occasional cleaning, protection from moisture and heat). Artisanal straps from Casati Milano, crafted with premium leather, extend durability to 7+ years whilst maintaining excellent aesthetic standards.
