Strap for DolceVita 23 Quartz Stainless Steel - Pink Gold Gold / Two-Tone Roman / Bracelet

The lug width of the Longines DolceVita L5.512.5.75.7 (alternative reference L55125757) measures exactly 17 millimetres. This non-standard dimension is specific to this feminine-proportioned model and requires bespoke aftermarket straps. To verify, use a digital calliper positioned perpendicularly between the inner shoulders of the lug, where the strap interfaces, excluding the attachment holes.

Alligator represents the most congruent aesthetic choice: its uniform scale pattern amplifies the model's inherent visual lightness and dialogues elegantly with the rose gold case. Black or deep brown alligator creates tonal contrast, whilst shell cordovan—if sourced in 17 millimetres—offers legendary durability with a patina that evolves over time. French calfskin with polished finish remains a versatile alternative for daily wear.

Strap replacement requires a spring bar remover tool or professional service intervention. Position the watch with lug facing upward, insert the remover's tip into the small lateral hole of the lug's retaining spring, press gently to disengage the spring, then extract the lug pin. Repeat on the opposite side. Installation of the new strap follows the inverse procedure, ensuring the retaining springs engage with an audible click.

Any bespoke strap with a 17-millimetre lug width interfaces compatibly with the Longines DolceVita L5.512.5.75.7. Online at milanostraps.it, a dedicated selection of 17mm straps is available in alligator, calfskin, shell cordovan and structured rubber. Always verify lug width prior to purchase to avoid incompatibility.

A premium leather strap (alligator, French calfskin, shell cordovan) with moderate daily use typically lasts 3 to 7 years. European alligator offers superior resistance due to its dense scale structure. Longevity depends upon ambient humidity, frequency of use, perspiration exposure and maintenance: avoid prolonged water immersion, dry the surface regularly and store in a ventilated location. Casati Milano's bespoke warranty covers 18 months from delivery.
