Strap for Sky-Dweller Stainless Steel - White Gold / Green / Oyster

The lug width of the Rolex Sky-Dweller 336934-0001 is 22 millimetres. This width is specific to this model and the entire Sky-Dweller range. Measurement must be taken perpendicularly between the two attachment points of the case using a digital calliper, ensuring accuracy within 0.1 millimetres to guarantee a secure, play-free fit.

For the Rolex Sky-Dweller 336934-0001, we primarily recommend high-quality alligator leather with vegetable tanning and vertical grain: the material enhances the white gold's prestige and develops an elegant patina over time. Alternatively, English calf with vegetable tanning offers versatility and a pleasant tactile roughness. Shell cordovan guarantees stiffness and optical brilliance, whilst a technical rubber strap remains the ideal option for humid climates or extended travel.

Changing the Sky-Dweller's strap requires a specific tool (spring bar tool). First, remove the watch from your wrist. Position the spring bar tool in the minute lateral spaces of the lug, exerting gentle downward pressure to release the internal spring. Once one side is disengaged, remove the old strap. Insert the new strap first on one side, then the other, ensuring the spring bar clicks into position with an audible snap. We recommend this operation be performed at an authorised Rolex service centre to prevent case damage.

The Rolex Sky-Dweller 336934-0001 is compatible with any artisanal strap specifically crafted for the 22-millimetre lug width. Milano Straps offers a comprehensive collection of 22mm straps in alligator, calf, shell cordovan and rubber, all constructed to quality standards consistent with this watch's status. Always verify that the strap is marked '22mm' and that the lugs insert without forcing.

The longevity of a leather strap depends on material and intensity of use. Vegetable-tanned alligator has an average lifespan of 3–5 years with daily wear; calf leather, owing to its greater porosity, typically lasts 2–3 years. Shell cordovan, thanks to its density, can exceed 5 years. A technical rubber strap readily achieves 3–4 years. Leather ageing is natural: when the strap shows severe cracking or elasticity loss, replacement is advisable. The 18-month warranty offered by Casati Milano covers manufacturing defects, not ordinary wear.
