Strap for DolceVita 20 Quartz Two Tone

The lug width of the Longines DolceVita L5.155.5.28.7 (also referenced as L51555287) is 15 millimetres, measured from inner shoulder to inner shoulder of the lugs. This uncommon dimension requires careful attention when selecting a strap: an oversized lug width would compromise the proportional balance of the 19.80mm case.

For the DolceVita L5.155.5.28.7, alligator leather with vegetable tanning represents the ideal stylistic choice: its regular grain complements the rectangular elegance of the two-tone case. Alternatively, vegetable-tanned calf in cognac develops warm harmony whilst enhancing the yellow gold. Shell Cordovan is not recommended, as its substantial thickness would overwhelm the case's slender proportions.

Strap replacement requires extraction of the spring bars from the lugs using a dedicated spring bar tool. The DolceVita employs standard spring bars: position the tool, apply gentle pressure to the bar and slide it laterally to release. We recommend consulting a specialised artisan to prevent the risk of scratching the two-tone case.

A natural leather strap—alligator or calf—with vegetable tanning maintains structural functionality for 3–5 years with regular use, developing patina and colour variations. Longevity depends on frequency of wear, ambient humidity and sun exposure. Rubber or synthetic straps offer greater durability, although they are less congruent with this model's stylistic identity.
