Frequently asked questions

What is the exact lug width of the Rolex Sky-Dweller 326938-0001?

The lug width of the Rolex Sky-Dweller 326938-0001 is 21 millimetres. This measurement is taken from the internal upper attachment point to the internal lower attachment point of the case, perpendicular to the casing. Rolex factory tolerance is ±0.2mm. When ordering an aftermarket strap, it is essential to specify not only "21mm" but also the desired buckle type (deployant, passing spring bars, or quick-release buttons) to ensure correct compatibility.

Which strap material is most suitable for the Sky-Dweller 326938-0001?

For the Sky-Dweller 326938-0001 in yellow gold, alligator leather represents the aristocratic solution, as the natural texture and evolutionary patina reflect Rolex's constructive principles. Shell cordovan is ideal for those seeking durability and development of chromatic depth over time. Vegetable-tanned calf leather offers the best compromise between initial softness and resistance for daily wear. FKM rubber is the technical choice for sporting activities and extreme durability.

How do you change the strap on the Rolex Sky-Dweller 326938-0001?

The Rolex Sky-Dweller 326938-0001 is equipped with an integrated Oyster bracelet and requires specific technical competencies for strap replacement. It is advisable to contact an authorised Rolex service centre or a specialised craftsman such as Casati Milano. If the strap is equipped with a deployant, the replacement is simplified; otherwise, workshop intervention may be necessary to avoid damaging the case lugs.

Is an aftermarket strap compatible with the Rolex Sky-Dweller 326938-0001?

Yes, an aftermarket strap with a 21mm lug width is compatible with the Rolex Sky-Dweller 326938-0001. It is essential to verify the exact width (21mm ±0.2mm) and the buckle type. Many artisanal manufacturers, including Casati Milano, produce custom 21mm straps specifically designed for this model, guaranteeing construction quality and aesthetics consistent with the luxury context.

How long does a leather strap last on the Sky-Dweller 326938-0001?

The durability of a leather strap depends on the material and usage. Alligator and shell cordovan, if crafted with traditional tanning, have a useful life of 3-5 years with daily wear, with the possibility of replacement thereafter. Vegetable-tanned calf leather lasts 2-3 years under intensive wear conditions. Casati Milano offers an 18-month warranty on manufacturing defects, and periodic maintenance (hydration with specific creams) significantly extends the life of the strap.
