FAQ
What is the lug width of the Rolex Datejust 31 278384rbr-0016?
The Rolex Datejust 31 278384rbr-0016 has a lug width of 16mm. This measurement is taken internally between the two lugs at the point of contact with the case and does not correspond to the overall bezel width. A digital calliper is recommended to verify the dimension before purchasing an aftermarket strap.
What is the best strap for the Rolex Datejust 31 278384rbr-0016?
For the bi-material case in Oystersteel and white gold of the 278384rbr-0016, a 16mm glossy alligator strap is the most coherent choice for formal occasions. Vegetable-tanned shell cordovan is ideal for refined daily wear, developing a unique patina over time. For sport or outdoor use, vulcanised rubber ensures durability and moisture resistance.
How do you change the strap on a Rolex Datejust 31?
To remove the original strap from the Datejust 31, a spring bar tool is required. The 16mm spring bars are located within the case lugs; compressing the spring-loaded tips releases them from the lug holes. It is advisable to work on a soft surface to avoid scratching the white gold and steel case. Spring bars are included with all Casati Milano straps.
Are there aftermarket straps compatible with the Rolex Datejust 31 278384rbr-0016?
Yes. Any strap with a 16mm lug width and standard spring bars is compatible with the Datejust 31 278384rbr-0016. Milano Straps offers a selection of handcrafted straps in various materials — alligator, calf leather, shell cordovan, rubber, NATO — available bespoke or ready to purchase online, all supplied with spring bars.
How long does a leather strap last on a Rolex Datejust 31?
The lifespan of a leather strap depends on the material, maintenance and frequency of use. A quality alligator strap, kept away from water and perspiration, can last between three and seven years. Vegetable-tanned shell cordovan is particularly durable and tends to improve with age through natural patina development. All Casati Milano straps carry an 18-month manufacturing guarantee.
