Frequently asked questions

What is the exact lug width of the Rolex Datejust 36 reference 116244-0012?

The lug width of the Rolex Datejust 36 reference 116244-0012 is precisely 20 millimetres. This measurement refers to the distance between the lugs (strap attachment points) on the case. It is critical to verify this specification before purchasing a replacement strap: a 18mm or 22mm strap will not fit properly and attempting to force it may damage both the case and the strap.

Which strap material is recommended for a Datejust 36 with mother-of-pearl dial?

For the white mother-of-pearl dial paired with the white gold and stainless steel case, cognac-brown alligator leather is the classical choice that elevates formal sophistication. Alternatively, shell cordovan develops a magnificent patina over time with natural colour deepening. Vegetable-tanned calf leather offers a more contemporary aesthetic. Sport rubber straps with textile inserts are practical for daily wear and maintain the watch's dignity without aesthetic compromise.

How do you change the strap on a Rolex Datejust 36 116244-0012?

Strap replacement requires specialised tools: a spring bar remover and spring bar pen. Position the watch on a soft pad with the dial facing down. Insert the tool into the small hole on the lug to compress the spring bar retaining mechanism, withdraw the spring bar from the old strap, position it into the new strap's holes, and re-insert with gentle pressure until it clicks into place. Repeat for both sides. If you lack experience, consult a professional watchmaker: improper handling can scratch the case.

Is an aftermarket 20mm strap compatible with the Datejust 36 116244-0012?

Yes, any 20mm strap with standard spring bars is physically compatible. Compatibility with the watch's aesthetic and longevity, however, depends on construction quality. Premium leather straps in alligator, calf, or shell cordovan with professional tanning maintain the Rolex's heritage value over time. Avoid synthetic leather straps of inferior quality—they diminish the watch's character.

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

A premium artisanal leather strap in vegetable-tanned calf or alligator typically lasts 3–5 years with daily intense use. Shell cordovan, owing to its fibrous structure, can exceed 7 years. Longevity is influenced by sun exposure, humidity, water contact, and maintenance: applying protective balm every six months significantly extends lifespan. Synthetic leather straps degrade visibly within 1–2 years.
