Strap for Sky-Dweller Yellow Gold / Champagne Arabic

The Rolex Sky-Dweller 326938-0002 features a lug width of 21.00 millimetres. This measurement refers to the distance between the two metal pins that protrude from the case and accommodate the strap. Measurement is performed perpendicular to the horizontal axis of the watch, with the strap removed, using a digital calliper or graduated ruler positioned on the underside of the case between the two fixing pins.

For the Sky-Dweller 326938-0002 in yellow gold, an alligator strap is the most natural choice, reflecting the elegance of the case and allowing the cross-grain texture of the back to express sophisticated craftsmanship. Brown or black alligator pairs flawlessly with yellow gold. An elegant alternative is vegetable-tanned calf, which acquires patina over time. For intensive use, non-tannin calf proves more resistant to climatic variations.

The change requires removal of the spring bars that secure the strap to the case lugs. Use a spring bar tool — an instrument resembling a small rounded-tip lever — to compress the internal spring, freeing the strap. Insert the tip gently into the lateral groove of the pin, push downward to compress the spring, and retract the strap. The process requires care to avoid scratching the yellow gold case.

Yes, any strap with a 21-millimetre lug width is compatible with the 326938-0002. The spring bar pin measurement must correspond exactly: 21mm. Artisanal straps in alligator, calf, shell cordovan or alternative materials can be adapted, provided the lug width is correct. Always verify compatibility with the manufacturer before purchase.

A quality leather strap has a lifespan of three to five years under moderate use, provided it is exposed to limited climatic fluctuations. Durability depends on tanning: vegetable-tanned leather matures and hardens progressively; non-tannin calf maintains consistent softness but wears more quickly in high-humidity regions. The inner strap wears primarily in the three millimetre zone around the flex point. Annual inspection allows you to detect excessive wear and plan replacement.
