Frequently asked questions

What is the lug width of the Royal Oak Offshore 26202AU.OO.D002CA.01?

The lug width of the Royal Oak Offshore 26202AU.OO.D002CA.01 is 16mm. This measurement should be taken with a digital calliper between the two inner lugs at their narrowest point. All 16mm straps with straight or slightly curved ends are compatible with this reference.

What is the best strap for the Audemars Piguet Royal Oak Offshore 26202AU.OO.D002CA.01?

Given the titanium, carbon and cermet case construction, the most aesthetically coherent strap choices are: hornback alligator in black or midnight blue for an elegant contrast, natural shell cordovan for a noble ageing with deep patina, or vulcanised rubber for daily sporting use. A titanium deployant clasp completes the pairing without introducing material discontinuity.

How do I change the strap on a Royal Oak Offshore with 16mm lugs?

Changing the strap on this model requires 16mm springbars of appropriate length. Use a springbar tool to release the springbars from the case lugs. The operation requires care: the titanium lugs on the Royal Oak Offshore have a specific internal curvature, so it is advisable to consult a watchmaker or choose straps supplied with pre-fitted springbars.

Are there aftermarket straps compatible with the Royal Oak Offshore 26202AU.OO.D002CA.01?

Yes. This reference features a standard 16mm lug width that accepts high-quality aftermarket straps. Casati Milano crafts bespoke straps in leather, rubber and technical materials calibrated to this measurement, with attachment profiles designed to follow the curvature of the original Audemars Piguet lug for a precise fit.

How long does a leather strap last on a 42mm Royal Oak Offshore?

The lifespan of a leather strap depends on frequency of use and maintenance. A quality alligator strap with vegetable tanning, worn in rotation with other straps, typically lasts 3–5 years before showing structural wear. Casati Milano straps carry an 18-month warranty against manufacturing defects. To maximise longevity, avoid prolonged contact with water and perspiration, preferring rubber for intensive sporting use.
