Strap for DolceVita 20 Quartz Two Tone

The lug width of the Longines DolceVita L5.155.5.70.7 is 15mm. This measurement is specific to this model and determines compatibility with aftermarket watch straps. To verify the lug width, insert a ruler between the lugs at their narrowest point and measure the internal distance, which should be exactly 15mm.

For the DolceVita L5.155.5.70.7, we recommend an alligator strap. The faceted texture and regular grain of reptile leather dialogues elegantly with the rectangular geometry of the case. Warm mahogany or hazelnut brown alligator enhances the preciousness of yellow gold, whilst smooth polished calf leather amplifies formality for dress occasions. The patina that alligator develops over time emphasises the character of a watch built to age with dignity.

Changing the strap is a straightforward operation. Use a spring bar tool to gently extract the pins from the case lugs. Insert the new 15mm strap onto the pins, ensuring that the retaining springs click correctly into their seats. Avoid forcing: a strap compatible with a 15mm lug width should slide on without excessive resistance. If preferred, you may visit a watchmaker for this task.

Yes, absolutely. Any strap with a 15mm lug width is compatible with the DolceVita L5.155.5.70.7. The aftermarket offers a wide range of options: alligator, calf, Shell Cordovan, rubber and fabric. The key is to verify that the lug width is precisely 15mm and that the strap has been crafted to standards appropriate for a watch of this value and category.

The lifespan of a leather strap depends on the material and usage. Quality alligator, if properly maintained and worn regularly without excessive moisture, can last 5-8 years. Calf leather, being more delicate, typically lasts 3-5 years. Vegetable-tanned leather, being more resistant to scratches, can exceed 10 years. Atelier Casati Milano offers an 18-month warranty on all bespoke straps, guaranteeing replacements for manufacturing defects.
