Strap for Presence 38.5 Quartz PVD Gold / Champagne / Bracelet

The lug width of the Longines Presence L4.790.2.32.8 is 20 millimetres. This measurement represents the distance between the two inner lugs of the case where the strap attaches. A compatible strap must have a width between 19.8 and 20.2 millimetres to ensure proper fit without lateral play or insertion difficulties.

For the Presence L4.790.2.32.8, the best strap is natural alligator with vegetable tanning. This material respects the sober identity of the steel case and develops a natural patina over time. Alternatively, shell cordovan from horse leather offers legendary durability and ages magnificently, whilst fine calf leather remains the choice for those preferring greater aesthetic versatility between formal and casual.

Strap change is straightforward: remove the old strap using a spring bar tool to gently lever the small pins connecting the strap to the case. Once the pins are removed, extract the old strap. Insert the new strap by aligning the lateral holes to the pins, then push the pins into position until they click securely. If unfamiliar with the procedure, it requires approximately 5 minutes. Atelier Casati Milano also offers home strap change service.

Technically yes, provided the strap has an effective lug width of 20 millimetres (±0.2mm). However, not all aftermarket straps respect engineering tolerances: many economy straps suffer from thickness variations at attachment points causing lateral play. Artisanal quality straps, constructed with precise tolerances and noble leathers, guarantee correct fit and longevity of 10-15 years.

A noble leather strap with vegetable tanning lasts approximately 5-8 years with daily wear. Longevity depends on exposure to perspiration, humidity and leather care. Shell cordovan, due to its dense fibrous structure, can last 10-15 years. Vegetable-tanned leather ages naturally, developing a unique patina. To extend lifespan, it is advisable to dry the strap after perspiration and condition the leather every 6 months with specific products.
