Strap for DolceVita 16 Quartz Two Tone

The lug width of the Longines DolceVita L5.158.5.70.7 is 12mm. This is a non-standard measurement specific to this model, requiring bespoke strap construction. To measure the lug width accurately, position a ruler between the two metal pins protruding laterally from the case: the measurement in millimetres represents the precise lug width.

For the Longines DolceVita L5.158.5.70.7, we recommend three options: natural alligator for conservative elegance (smaller scales adapt perfectly to 12mm lugs), vegetable-tanned calf for contemporary character and natural patina development, or cordovan in reddish tones for humidity resistance and natural lustre. We advise against rubber and technical textiles, as they would undermine the refined identity of the model.

Strap replacement requires a spring bar tool: a bi-pronged instrument that allows you to push the metal pins inward to release the old lug. Extract the pin from one side, then the other, remove the worn strap and insert the new one by reversing the procedure. If you lack the tool or feel uncertain, consult a professional watchmaker or the Casati Milano atelier for assistance.

Yes, aftermarket 12mm straps are fully compatible with the Longines DolceVita L5.158.5.70.7, provided they respect the lug width (12mm) and proportions of the slender, compact case. Milano Straps offers a curated selection of 12mm straps in various materials, from alligator to calf, all constructed to artisanal standards and compatible with this Longines model.

The lifespan of a leather strap depends on usage, climate and material quality. A high-quality alligator or cordovan strap typically lasts 3–5 years with daily wear. Vegetable-tanned calf can endure 2–4 years, developing an attractive patina over time. Regular maintenance (wrist hygiene, protection from excessive heat and humidity) and rotation with alternative straps significantly extend longevity. Casati Milano provides an 18-month warranty on all bespoke atelier straps.
