Frequently asked questions

What is the lug width of the Rolex Datejust 36 126234-0013?

The Rolex Datejust 36 126234-0013 has a lug width of 20 mm. This measurement is taken between the two case lugs using a digital calliper and remains consistent across the entire Datejust 36 family, regardless of dial or bezel variant. It is the essential parameter for selecting a compatible aftermarket strap.

What is the best strap for the Rolex Datejust 36 126234-0013?

For the Datejust 36 126234-0013 in white gold and steel bicolour, the most suitable straps are: vegetable-tanned alligator in cool tones (slate grey, midnight blue, burgundy) for formal wear, shell cordovan for a compact and lustrous finish, and smooth-grain calf leather for everyday professional use. A brushed steel deployant clasp ensures material consistency with the case.

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

Changing the strap on the Datejust 36 requires a proper springbar tool: insert the tip into the lug hole, compress the springbar and slide it out laterally. Care must be taken to avoid scratching the case surfaces. If you are not experienced with this procedure, it is advisable to consult a watchmaker or visit the Casati Milano atelier, where fitting is included in the service.

Are there aftermarket straps compatible with the Rolex Datejust 36 126234-0013?

Yes. The Datejust 36 126234-0013 features 20 mm lugs, a size for which a wide range of artisan aftermarket straps is available. Milano Straps offers on milanostraps.it a curated selection of alligator, shell cordovan, calf leather, NATO and rubber straps, all crafted at 20 mm lug width and compatible with original Rolex springbars.

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

The longevity of a leather strap depends on the quality of the hide, the tanning method and daily use. A vegetable-tanned alligator strap, with proper care (kept away from water, excessive perspiration and heat sources), can last between 3 and 7 years while retaining its patina and structure. Milano Straps straps carry an 18-month warranty against manufacturing defects.
