Strap for DolceVita 20.5 Quartz Pink Gold / Diamond / Silver - Roman

The lug width of the Longines DolceVita L5.255.9.71.0 is 15 millimetres. It is measured from the tip of one lug to the other, in a straight line through the centre of the case. This unconventional measurement reflects Longines' design philosophy to maintain harmonious proportions between the compact case (20.50 mm diameter) and the strap. It does not accept adapters or improvisation: it requires straps specifically crafted at 15 mm.

Alligator is the canonical choice for the DolceVita in rose gold. Its regular quilted texture echoes the geometric order of the case, while the natural patina that develops over time creates chromatic depth. For those preferring softer tones, vegetable-tanned calf offers a gossamer texture that contrasts elegantly. Shell cordovan, with its intrinsic lustre and nervous grain, adds drama and is ideal for evening wear. Butadiene rubber redefines the model as a summer sports watch without loss of elegance.

Changing the strap on the DolceVita requires a tool called a spring bar tool. After gently removing the original strap by acting on the small lateral springs, it is sufficient to fit the new 15 mm strap into the lugs, ensuring it sits perfectly without protrusions. If you lack experience, it is advisable to entrust the operation to a watchmaker or specialist service such as Casati Milano, which guarantees millimetre precision and does not damage the case.

Yes, but with care. Only straps specifically crafted at 15 mm are compatible. Standard 16 or 18 mm straps would cause unacceptable lateral protrusions and damage the aesthetic balance of the case. Milanostraps offers a collection of ready-made 15 mm straps in alligator, calf and other materials, customisable in dimensions, initials and thread colour. For advanced leather selection, Casati Milano manufactures made-to-measure straps with an 18-month guarantee.

Durability depends on material and usage. High-quality alligator, with vegetable tanning, lasts 5–7 years under normal conditions, developing a fascinating patina. Calf ages faster, 3–5 years, but offers superior softness. Shell cordovan, due to its natural density, can last 8–10 years. Butadiene rubber maintains technical integrity longer (7–8 years) but loses lustre. Daily wear, sun exposure and humidity accelerate deterioration. Casati Milano offers an 18-month warranty on all made-to-measure straps.
