Strap for DolceVita 20 Quartz Two Tone Pink Diamond

The Longines DolceVita L5.155.5.79.7 features a lug width of 15 millimetres, a rare specification among contemporary timepieces. This measurement is proportionate to the rectangular case measuring 19.60 mm in diameter and preserves the model's characteristic stylistic harmony. To verify the lug width, measure the internal distance between the two spring bar holes after removing the original strap.

For the DolceVita L5.155.5.79.7, we recommend straps in alligator, vegetable-tanned calf leather, or shell cordovan. Alligator in cognac or dark brown tones dialogues elegantly with the mixed rose gold-stainless steel case. Dark brown calf leather offers versatility and develops a natural patina that harmonises beautifully with rose gold. Shell cordovan is ideal for those seeking a strap that ages progressively towards mahogany tones. All available with customised 15mm lug width.

Strap replacement occurs via removal of the spring bars. Use a specialised tool or consult a watchmaker. Position the spring bar from below, apply light and even pressure to avoid case damage, and slide it horizontally. Repeat with the second bar. Insert the new strap by aligning the lugs with the spring bars, then push the bar until it clicks into position. For safe and risk-free replacement, consult an expert or utilise Casati Milano's services.

The lifespan of a leather strap depends on material, usage and maintenance. Vegetable-tanned alligator, worn daily, typically lasts 3–5 years before replacement becomes necessary. Shell cordovan, if well maintained, may last 5–7 years whilst developing a fascinating patina. Vegetable-tanned calf leather tends to last 2–4 years. Rubber is more resistant to moisture but ages more quickly aesthetically (1–3 years). Keep the strap dry and away from heat sources to maximise longevity. Casati Milano straps benefit from an 18-month warranty.
