The Sky-Dweller 326138, seen from the bench

The Sky-Dweller was introduced in 2012 as a GMT watch with an annual calendar. It is powered by the automatic Caliber 9001 with an adjustable second time zone and month indicator through windows on the dial. The 42mm case is in yellow gold with 22mm lugs and a chronometer certification.

Frequently asked questions

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

The lug width of the Rolex Sky-Dweller 326138 is precisely 22mm. This measurement represents the distance between the two spring bar attachment points on the case. Accurate measurement using a calliper positioned directly on these attachment points is essential to ensure perfect compatibility.

What is the best strap material for the 326138?

For the yellow gold 326138, alligator leather with a fine grain in cognac or dark brown tones is the most aesthetically coherent choice. Alternatively, vegetable-tanned English calf leather ages naturally, or a technical NATO strap offers practicality. Shell cordovan in plum colour is a rarity that amplifies the watch's exclusivity.

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

Strap removal is straightforward: position the watch with lugs facing upward, insert a small flat tool (spring bar tool) between the lug and case, gently compress the spring bar, then slide the strap out. The new 22mm strap attaches identically, ensuring the spring bars lock securely at both ends.

Is an aftermarket strap compatible with the 326138?

Yes, any strap with a 22mm lug width is compatible. Verify that the passants are dimensioned to fit the case width without lateral protrusion. Bespoke artisanal straps with custom deployante clasp guarantee complete compatibility and optimal comfort.

What is the average lifespan of a leather strap for the 326138?

A quality leather strap (alligator, calf, shell cordovan) typically lasts 3–5 years with regular daily wear. Patina evolves naturally over time, increasing aesthetic appeal. Final wear depends on climate, usage frequency, and care: protection from extreme humidity and direct sunlight extends the strap's life beyond this estimate.
