Frequently asked questions
What is the lug width of the Rolex Datejust 31 278285RBR-0036?
The Rolex Datejust 31 ref. 278285RBR-0036 has a lug width of 16mm. This measurement is standard across the entire Datejust 31 family and should be verified using a digital calliper to measure the internal distance between the two lugs at the strap insertion point.
What is the best strap for the Rolex Datejust 31 278285RBR-0036?
For this Everose gold reference with a diamond-set bezel, a vegetable-tanned alligator strap represents the finest choice: the natural grain and patina that develops over time complement the precious case finishes beautifully. High-quality alternatives include polished box-calf leather for a formal aesthetic and shell cordovan for those who favour a compact texture and a sartorial appearance.
How do you change the strap on a Rolex Datejust 31?
To replace the strap on a Datejust 31, a forked spring bar tool sized for the 16mm spring bars is required. It is advisable to work on a soft surface to protect the Everose gold lugs from scratches. If in any doubt, it is preferable to consult a watchmaker or contact Casati Milano for dedicated assistance.
Are there aftermarket straps compatible with the Rolex Datejust 31 278285RBR-0036?
Yes, high-quality aftermarket straps compatible with the 16mm lug width of the Datejust 31 are available. Milano Straps offers a curated selection of handcrafted straps in 16mm width, made from selected leathers and designed to be fully compatible in shape and dimension with this Rolex reference.
How long does a leather strap last on a Rolex Datejust 31?
The lifespan of a leather strap depends on the type of leather, care routine and daily use. A quality vegetable-tanned alligator strap, rotated regularly and kept away from direct moisture, can last between 3 and 5 years whilst retaining a distinguished appearance. Calf leather tends to have a slightly shorter lifespan, whereas shell cordovan is among the most durable materials owing to its dense, compact fibre structure.
