Frequently asked questions

What is the lug width of the Reservoir Cars RSV01.LB/730-36?

The lug width of the Reservoir Cars RSV01.LB/730-36 is 20mm. This measurement refers to the distance between the two lugs of the case and is essential for selecting compatible straps. The measurement should be taken using a digital calliper, measuring from the inside of one lug to the inside of the other.

Which strap is most suitable for the Reservoir Cars RSV01.LB/730-36?

For the RSV01.LB/730-36, we recommend an alligator leather in medium grain with grey-anthracite or deep burgundy tones, or a vegetable-tanned calf leather in deep black that develops natural patina over time. Both materials enhance the vintage automotive aesthetic of the dial without overpowering the palladium case.

How do you change the strap on a watch with a 20mm lug width?

Changing the strap requires specific tools: a spring bar tool or a small flathead screwdriver. Position the watch on a stable surface, insert the tool into the slot on the lug, and gently lever to release the spring bar. Align the new strap holes with the spring bar and lever until it clicks into place.

Is an aftermarket 20mm strap compatible with the Reservoir Cars RSV01.LB/730-36?

Yes, any strap with a 20mm lug width is compatible with the RSV01.LB/730-36. However, we recommend choosing thicknesses consistent with the case proportions: for a 41.50mm case, a thickness of 4-5mm ensures elegant proportions without visual imbalance.

How long does a leather strap last on a watch used daily?

A quality leather strap, subjected to moderate daily use, has an average lifespan of 2-4 years. Vegetable-tanned leather, if regularly maintained (cleaning with damp cloth, natural drying), can last over 4 years and improves aesthetically over time. Prolonged exposure to humidity, sweat, and UV rays accelerates ageing.
