Strap for DolceVita 20 Quartz Two Tone Pink Diamond

The lug width of the Longines DolceVita L5.155.5.19.7 is 15 millimetres. This measurement is specific to the rectangular case design with a 19.60mm diameter, ensuring harmonious proportions on the wrist. To verify compatibility, measure the space between the lugs (the metal pins supporting the strap): it must be exactly 15mm. A compatible strap of this dimension ensures proper positioning without tension or excessive play.

The ideal strap depends on your style and usage. Mississippian alligator is the luxury choice for those seeking authenticity and durability; its veined texture complements the bicolour rose gold and steel case. Vegetable-tanned calf develops a natural patina over time and offers versatility. Shell cordovan provides sophisticated organic lustre. For a sportier look, a cotton-silk NATO or a rubber strap from vegetable tanning maintains elegance without sacrificing practicality. A deployant clasp is recommended for premium leather straps.

Changing the strap on the DolceVita is straightforward: position the watch on a soft surface (microfibre cloth). Locate the pins in the lugs (one on each side); using a specialised pin-removal tool or small lever, gently push the pin downward from the opposite side until it protrudes. Remove the old strap and insert the new one, aligning the holes. Reinsert the pin, ensuring it clicks securely on both sides. Work slowly to avoid scratching the case. If uncertain, consult a professional watchmaker.

The lifespan of a leather strap depends on the quality of craftsmanship, leather choice and usage. Premium alligator or shell cordovan can last 3–5 years with routine maintenance (occasional cleaning, protection from moisture). Vegetable-tanned calf, being more porous, typically lasts 2–4 years. To extend service life, avoid water immersion, limit exposure to humidity, and periodically clean with a soft cloth. Milano Straps straps include maintenance guidance; Casati Milano provides an 18-month warranty on repairs and buckle replacements.
