Frequently asked questions

What is the lug width of the Rolex Sky-Dweller 326138-0004?

The Rolex Sky-Dweller 326138-0004 features a 22mm lug width. This dimension is specific to the 42mm case diameter and is essential when selecting aftermarket-compatible straps. Any strap with a different lug width will not fit the metal lugs of the watch.

What is the best strap for the yellow gold Sky-Dweller 326138-0004?

American alligator remains the reference choice for aesthetic harmony and functionality: the natural grain dialogues with the watch's yellow tone, and the patina that develops creates a visible narrative of noble wear. For boldness, black alligator creates dramatic contrast. Shell Cordovan in cognac or burgundy amplifies the sense of intrinsic luxury. For those choosing ethics, vegetable-tanned calf leather in honey tones maintains warmth without compromise.

How do I change the strap on the Rolex Sky-Dweller 326138-0004?

To change the strap, you must remove the two spring bars that connect the strap to the case lugs. Use a dedicated spring bar tool, gently pushing the bar until it releases. Once both bars are disengaged, extract the old strap and insert the new bars into the replacement strap before securing to the case. If unfamiliar with the procedure, consult a watchmaker or Casati Milano.

Is a 22mm aftermarket strap fully compatible with the 326138-0004?

Yes, any 22mm strap is compatible in terms of lug width. However, aesthetic and functional compatibility depends on other factors: leather thickness (ideally 3-3.5mm), buckle type (whether using an original Rolex deployante or alternative), and chromatic harmony with the gold. Trusting specialised craftsmen like Casati Milano ensures conscious and lasting choices.

How long does a leather strap last on a Rolex Sky-Dweller?

A high-quality leather strap (alligator, Shell Cordovan, vegetable-tanned calf) worn daily lasts between 4 and 7 years before requiring repair or replacement. Longevity depends on frequency of wear, climate, sun exposure, and humidity. Leather tends to thin at stress points (pass-throughs) and the buckle may require servicing. With proper maintenance and protection from excessive stress, many artisanal straps exceed 10 years of useful life.
