The 36 mm case houses the caliber 3135 automatic movement with a power reserve of approximately 48 hours. The lug width measures 20 mm, precisely proportioned to the case diameter. The Cyclops lens magnifies the date window 2.5 times, while the rose gold smooth bezel and triple-sealed Twinlock crown ensure water resistance to 100 meters.

Frequently asked questions

What is the lug width of the Rolex Datejust 36 reference 116201-0098?

The lug width (ansa measurement) of the Rolex Datejust 36 reference 116201-0098 is 20 millimetres. This measurement is specific to the 36-millimetre case and ensures balanced proportions. To verify accurately, use a digital calliper positioned between the inner lug pins.

Which strap is most suitable for the Rolex Datejust 36 116201-0098?

For the two-tone Datejust 36, straps in natural alligator or vegetable-tanned calf leather are ideal. Alligator with belly grain offers formal elegance and visual contrast with the steel-rose gold case. Vegetable-tanned calf develops patina in harmony with the natural ageing of rose gold, creating superior aesthetic synergy. A soldered deployante clasp ensures elevated daily ergonomics.

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

Remove the strap by depressing the spring bars—the pins securing the strap to the lugs—using a dedicated spring bar tool. Press the pin inward on one side to create clearance for extracting the old strap. Insert the new strap by aligning its holes with the lugs, then release the pin. If uncertain, consult a certified watchmaker to prevent case damage.

Can you use an aftermarket compatible strap on the Datejust 36 116201-0098?

Yes, any strap with 20-millimetre lug width is compatible with the 116201-0098. Artisanal straps of superior quality to Rolex originals are available from specialists such as Casati Milano. Always verify that the strap is crafted from carefully selected leather and demonstrates refined construction to maintain your Rolex's aesthetic integrity.

How long does a leather strap last on a Rolex Datejust 36?

A quality leather strap—alligator or vegetable-tanned calf—typically lasts 3–5 years with daily wear and appropriate maintenance. Longevity depends on frequency of use, ambient humidity, and regular care: apply neutral balm every six months to maintain elasticity. Vegetable-tanned straps develop pleasing patina over time, whilst alligator maintains more uniform appearance. Avoid prolonged direct sunlight and highly humid environments.
