Frequently asked questions
What is the lug width of the Rolex Datejust 31 ref. 178273-0083?
The Rolex Datejust 31 ref. 178273-0083 has a lug width of 16mm. This measurement refers to the internal distance between the Oyster case lugs and is the essential parameter to verify before purchasing any aftermarket or bespoke strap compatible with this reference.
What is the best strap for the Rolex Datejust 31 178273-0083?
For the 178273-0083, featuring a mother-of-pearl dial and Rolesor case (steel and yellow gold), belly-cut alligator straps in black, burgundy or moss green offer the finest balance between formal elegance and aesthetic coherence with the case materials. Vegetable-tanned calfskin in cognac tones enhances the warm reflections of the yellow gold lugs. For more active use, vulcanised rubber provides water resistance without compromising the overall appearance.
How do you change the strap on a Rolex Datejust 31?
To replace the strap on the Rolex Datejust 31, you must remove the spring bars securing the original bracelet or strap to the case lugs. This requires a spring bar tool carefully inserted into the lateral notch of each lug. Always work on a soft surface to protect the case and bezel from scratches. If in doubt, it is advisable to entrust the operation to a watchmaker or specialist atelier.
Are there aftermarket straps compatible with the Rolex Datejust 31 178273-0083?
Yes, the aftermarket offers straps compatible with a 16mm lug width suitable for the Rolex Datejust 31.

Milanostraps.it offers bespoke handcrafted straps and an online selection of compatible 16mm straps, made from high-quality leathers with steel or gold buckles.
How long does a leather strap last on a Rolex Datejust 31?
