Strap for DolceVita 20.5 Quartz Stainless Steel / Diamond / Silver - Roman

The lug width of the Longines DolceVita L5.255.0.71.2 is 15 millimetres. This measurement is critical for strap compatibility and represents the linear distance between the two lugs that hold the strap, measured from the inner edge of one lug to the inner edge of the other. Always verify this measurement before purchasing any aftermarket strap.

For the DolceVita L5.255.0.71.2, alligator leather is recommended as it amplifies the Art Deco geometric theme of the case. Vegetable-tanned calf is an excellent versatile alternative. Shell cordovan offers depth of colour and develops a natural patina over time. The strap thickness should remain restrained, between 1.4 and 1.8 millimetres, to maintain the correct proportions of the thin case.

To change the strap, you will need a spring bar tool with a forked tip. Insert the fork around the spring bar holding the strap, lifting gently to free one end of the bar from its seat in the case. Repeat for the other side. Once the old spring bars are removed, insert the new strap and secure the bars in their seats. If you prefer to avoid the risk of scratches, entrust the work to a specialist watchmaker.

Yes, provided the strap is compatible with the 15-millimetre lug width. Many aftermarket straps, particularly those in fine leather, are available in this size. Always verify compatibility with the retailer and ensure the strap has been specifically manufactured for watches with 15mm lugs to guarantee a perfect fit and long durability.

The lifespan of a leather strap depends on the quality of the leather and daily use. A high-quality alligator or shell cordovan strap can last 3–5 years with regular maintenance (cleaning with a damp cloth, rapid drying). Vegetable-tanned leather ages naturally, developing a characteristic patina. Factors such as humidity, prolonged sun exposure and perspiration accelerate wear. A NATO fabric strap is more durable but requires periodic cleaning.
