The Datejust 36 116231-0096, seen from the bench

The Rolex Datejust 36 116231-0096 is the contemporary evolution of an icon created in 1945. This version combines 18-karat rose gold and Oystersteel in a 36 mm case with 11.5 mm thickness and 20 mm lug width. The watch features a unidirectional rotating bezel, sapphire crystal with 2.5x Cyclops lens over the date window, and is powered by the automatic Rolex caliber 3135 (28,800 semi-oscillations per hour, COSC certified). The bicolor configuration pairs warm champagne-toned rose gold with corrosion-resistant 904L steel, with rose gold applied indices on a sunburst dial.

Frequently asked questions

What is the lug width of the Rolex Datejust 36 116231-0096?

The Rolex Datejust 36 116231-0096 has a lug width of exactly 20 mm. This measurement is taken from the inner space of the upper lug to the passant hole, down to the inner space of the lower lug. A deviation of even 1 mm will result in a strap that either fails to close properly or rattles against the case. If you are uncertain about your measurement, Casati Milano offers free guidance via WhatsApp.

What is the best strap for the Datejust 36 116231-0096?

The choice depends on intended use and personal taste. For absolute elegance: dark brown alligator or black shell cordovan. For everyday versatility: anilline calf in cognac or grey tones. For sport and durability: Oysterflex rubber in anthracite or grey. The two-tone rose gold and steel case pairs beautifully with navy or olive alligator, which complements the warm tone of rose gold. Visit Casati Milano's atelier to handle materials and choose under natural light.

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

The Datejust 36 uses spring bars (springed pins) to attach the strap to the case lugs. Using a spring bar tool, compress the internal spring from one side, insert the blunt tip into the designated hole, and extract the old bar. Replace with your new strap, ensuring the inner lugs align perfectly with the holes. If you are inexperienced, consult a certified watchmaker—the risk of scratching the case is real and significant.

Can I fit an aftermarket strap on this Rolex?

Yes, provided it meets the 20 mm lug width specification. Straps from milanostraps.it are 100% compatible with the Datejust 36 116231-0096. Always verify that the internal lug attachment—thickness, width, and passant hole profile—matches exactly. Casati Milano tests every strap before dispatch to ensure precision fit and finish.

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

Longevity depends on material type and usage patterns. A quality alligator or shell cordovan strap, with proper care (avoid prolonged sweat, humidity, extreme heat, direct sunlight), can last 5–8 years of daily wear. Anilline calf, more delicate, typically lasts 3–5 years before significant wear appears. Casati Milano straps carry an 18-month warranty against manufacturing defects; natural wear is excluded. Rotate straps seasonally (one for summer, one for winter) to distribute stress evenly.
