Frequently asked questions
What is the lug width of the Rolex Datejust 31 178274-0061?
The Rolex Datejust 31 reference 178274-0061 has a lug width of 16 mm. This measurement is specific to the Datejust 31 family and requires straps with an exact 16 mm attachment width to ensure a proper fit between the case lugs and the strap keeper.
What is the best strap for the Rolex Datejust 31 178274-0061?
For the Datejust 31 178274-0061 in two-tone Rolesor (stainless steel and white gold), a vegetable-tanned alligator strap is the most coherent choice with the watch's formal character. Alternatively, grained calf leather suits everyday versatility, while shell cordovan offers a more distinctive personality. A deployant clasp in steel extends the life of any leather strap.
How do you change the strap on a Rolex Datejust 31?
To replace the strap on the Datejust 31, you will need a dedicated spring bar tool to remove the spring bars securing the strap to the case lugs. Work on a soft surface to protect both the case and dial. If in doubt, the operation can be carried out by a qualified watchmaker or at an atelier such as Casati Milano.
Are there aftermarket straps compatible with the Rolex Datejust 31 178274-0061?
Yes, there are many aftermarket straps compatible with the Datejust 31 178274-0061, provided they feature a 16 mm attachment width. Milano Straps offers a curated selection of handcrafted leather, NATO, and rubber straps specifically sized for this lug width, finished by hand at the Casati Milano atelier.
How long does a leather strap last on a Rolex Datejust 31?
The lifespan of a leather strap depends on material quality, frequency of use, and care. A high-quality alligator or shell cordovan strap with vegetable tanning can last between 3 and 7 years with regular maintenance. Using a deployant clasp significantly reduces mechanical stress on the lining, extending the strap's service life. Milano Straps provides an 18-month warranty against manufacturing defects.
