Frequently asked questions

What is the lug width of the Rolex Datejust 31 178344-0060?

The lug width of the Rolex Datejust 31 178344-0060 is 16mm. This measurement represents the distance between the two attachment points of the strap on the case and is essential for compatibility. It is important to measure correctly using a digital calliper to ensure that the purchased strap is perfectly compatible with the case lugs.

Which strap is recommended for the Datejust 31 178344-0060?

For the Datejust 31 178344-0060 in Rolesor (white gold and steel), we recommend alligator straps in dark brown (ebony or cognac) for classic elegance, or vegetable-tanned calf leather for those preferring softness and natural ageing. Black rubber is ideal for a more contemporary and sporty approach. All must feature 16mm lug width.

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

Strap replacement requires removal of the spring bar from the two case lugs. It is recommended to use a dedicated spring bar remover tool or consult a qualified watchmaker. The new strap must be inserted with the spring bar correctly positioned until the locking click is heard. The Casati Milano atelier provides personalised advice and installation support.

Can you use a compatible aftermarket strap on a Rolex Datejust 31?

Yes, any strap with a 16mm lug width is mechanically compatible. However, to preserve the value and aesthetics of the watch, it is essential to choose materials of equivalent quality: alligator, vegetable-tanned calf, FKM rubber or nato of excellent craftsmanship. Avoid inexpensive synthetic straps that could damage the case.

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

The durability of a leather strap depends on the material, usage and maintenance. Vegetable-tanned alligator typically lasts 3-5 years of daily wear; French calf 2-4 years. Constant exposure to humidity, sunlight and perspiration accelerates ageing. Casati Milano offers an 18-month warranty on manufacturing defects and recommends periodic maintenance to extend strap lifespan.
