FAQ

What is the lug width of the Rolex Datejust 36 116234-0089?

The lug width of the Rolex Datejust 36 ref. 116234-0089 is 20 mm. This measurement is taken with a digital calliper between the two lower lugs of the case, at the strap attachment point. It is the essential parameter for selecting any aftermarket strap compatible with this reference.

What is the best strap for the Rolex Datejust 36 116234-0089?

For the Rolex Datejust 36 116234-0089 in white gold and stainless steel, the most suitable materials are alligator leather in a glossy or matte finish, shell cordovan for those who appreciate a natural patina developing over time, and vegetable-tanned calf leather for more active daily use. A deployant clasp in stainless steel or 18-carat white gold provides the best fit and even pressure distribution on the wrist.

How do you change the strap on a Rolex Datejust 36?

The strap on a Rolex Datejust 36 is replaced by removing the spring bars connecting the strap to the case lugs. A bifurcated spring bar tool is required to compress the spring bar ends and release them. The operation requires care: the OYSTERSTEEL lugs can be scratched if an inappropriate tool is used. When ordering a bespoke strap from Casati Milano, correctly sized spring bars for the Datejust 36 lugs are included.

Are there aftermarket straps compatible with the Rolex Datejust 36 116234-0089?

Yes. Aftermarket straps compatible with the Rolex Datejust 36 must have a lug width of 20 mm with straight or slightly shaped ends and a heel thickness not exceeding 4 mm to fit correctly beneath the Oyster case. Milano Straps offers handcrafted straps in various materials and finishes, made specifically for the 20 mm lug width, available online or customisable through the Casati Milano atelier.

How long does a leather strap for the Rolex Datejust 36 last?

The lifespan of a leather strap depends on the material, care, and frequency of use. A high-quality alligator leather strap, if rotated with other straps and stored away from heat and moisture, can last between 3 and 6 years whilst retaining its structural and aesthetic integrity. Shell cordovan, due to the dense fibre structure of the horse's muscle band, tends to last longer and develops a distinctive patina. Milano Straps straps are covered by an 18-month manufacturing warranty.
