Strap for DolceVita 20 Quartz Two Tone Pink Diamond

The lug width of the Longines DolceVita L5.155.5.99.7 is 15 mm. This measurement represents the distance between the two attachment points of the strap on the case. It is a non-standard size, so it is important to verify strap compatibility before purchase.

For the DolceVita L5.155.5.99.7 in rose gold and mother-of-pearl, black or cognac brown alligator is the optimal choice. The regular texture of alligator perfectly complements the tonneau geometry of the case. Aniline vegetable-tanned calf is an excellent alternative for those seeking a naturally developed patina over time. Fabric or rubber straps are not recommended, as they would visually overwhelm the delicate case.

The strap is changed using a specific tool called a spring bar removal tool. Position the bifurcated end of the tool under the spring bar that holds the strap to the lugs, press upward to compress the spring, and extract the pin. Repeat on the other side. Insert the new strap by reversing the procedure, ensuring the spring is fully positioned in the locking holes.

Yes, you can use any quality aftermarket strap with a 15 mm lug width. It is essential to verify that the strap is precisely 15 mm and not approximated to 14 or 16 mm. An incorrectly sized strap could cause friction on the lugs or fit loosely. Quality leather straps (alligator, cordovan, vegetable-tanned calf) are recommended to maintain the aesthetic standard of the watch.

The lifespan of a leather strap depends on usage and material. A quality alligator or cordovan strap has an average lifespan of 3-5 years with regular daily use. Vegetable-tanned calf typically lasts 2-3 years, as natural tanning makes it more susceptible to wear. Replacement is recommended when the strap shows evident signs of cracking, structural weakness, or when the attachment points begin to fail. Regular maintenance (gentle cleaning and conditioning) can significantly extend strap life.
