Frequently asked questions

What is the lug width of the Rolex Datejust 31 278241-0031?

The Rolex Datejust 31 278241-0031 features a lug width of 16mm. This measurement corresponds to the internal distance between the case lugs and is the essential figure for selecting a compatible aftermarket strap. It can be verified using a digital calliper measured at the spring bar attachment point.

What is the best strap for the Rolex Datejust 31 278241-0031?

For the Datejust 31 278241-0031 in Rolesor Everose, straps in vegetable-tanned alligator or box-calf leather are the most fitting choices for its formal register. The natural grain of alligator develops a personalised patina over time, whilst box-calf offers a slim profile suited to both casual wear and formal attire. For sporting use, vulcanised rubber maintains the case's water resistance and provides secure grip on the wrist.

How do you change the strap on a Rolex Datejust 31?

The strap on the Rolex Datejust 31 is secured to the case via standard 16mm spring bars. Replacement requires a spring bar tool or a thin flat-head screwdriver to release the spring bars from the lugs. It is advisable to work on a soft surface to avoid scratching the case. Alternatively, any professional watchmaker can perform this operation within minutes.

Are there aftermarket straps compatible with the Rolex Datejust 31 278241-0031?

Milanostraps.it offers a selection of handcrafted straps in leather, rubber, and textile specifically designed for this size, with customisable lengths and buckle options to accommodate any wrist circumference.

How long does a leather strap last on a Rolex Datejust 31?

The lifespan of a leather strap depends on leather quality, tanning method, and frequency of use. A high-quality vegetable-tanned alligator strap, properly maintained, can last between three and five years whilst retaining its structural and aesthetic integrity. Box-calf offers comparable longevity. Shell cordovan, owing to its closed-pore surface, is among the most durable options. It is essential to avoid prolonged water exposure and to apply leather conditioner periodically.
