Sky-Dweller 326139— lug 22mm

The lug width of the Rolex Sky-Dweller Ref. 326139 is 22 millimetres. This measurement is specific to this model and must be respected with precision to ensure proper seating of the strap in the mounting points of the white gold case.

For the 326139 in 18-carat white gold with ivory dial, alligator represents the ideal choice from both aesthetic and functional perspectives. A cream-white or cognac-brown alligator maintains visual balance with the noble materials of the case. A valid alternative is vegetable-tanned calf, which adds tactile depth, or shell cordovan in cool tones for those seeking evolved patina and luxury presence over time.

The Rolex Sky-Dweller 326139 features a screw-through lug system passing through the lateral lugs. It is advisable to consult a specialised atelier such as Casati Milano, where strap replacement is performed with metronomic precision using dedicated tools, preventing damage to the white gold case and ensuring proper securing of the new strap.

Yes, an aftermarket strap with a 22 mm lug width is entirely compatible with the 326139, provided it is constructed with precision and uses quality materials (alligator, calf, shell cordovan) that respect the constructive philosophy of the model. Casati Milano offers bespoke 22 mm straps specifically designed for this watch family.

A high-quality alligator, calf, or shell cordovan strap, subjected to moderate use, maintains structural and aesthetic integrity for 4–6 years. Wear accelerates with exposure to moisture, frequent perspiration, and excessive flexing. A vulcanised rubber strap has greater longevity, up to 8–10 years with regular maintenance. Casati Milano offers an 18-month warranty on all manufacturing defects.
