Frequently asked questions
What is the lug width of the Rolex Datejust 31 reference 178271-0005?
The lug width of the Rolex Datejust 31 reference 178271-0005 is 16 millimetres. This dimension is standard for 31mm Datejust models and is determined by the distance between the case lugs. It is essential to verify this measurement before purchasing an aftermarket strap to ensure perfect compatibility and faultless installation without forcing.
Which strap is recommended for the Rolex Datejust 31 178271-0005?
For the Datejust 31 in Rolesor Everose, we recommend straps in natural alligator or vegetable-tanned calf leather that enhance the two-tone case. Black or dark brown alligator respects the watch's formality, whilst a cognac-coloured calf creates a sophisticated chromatic pairing with rose gold. The leather quality must reflect the watch's prestige: pleasant texture, uniform grain, consistent thickness.
How do I change the strap on the Rolex Datejust 31 178271-0005?
Strap replacement requires specific tools: a spring bar tool or dedicated remover. Position the watch on a stable surface, locate the upper lug, gently press the spring pin and remove the lug. Repeat for the lower lug. Insert the new strap by aligning the holes with the pins and ensuring the lug fastens correctly. We recommend having this operation performed by a qualified watchmaker to avoid damage to the case.
Can I use an aftermarket strap on the Rolex Datejust 31 178271-0005?
Yes, it is possible to use quality aftermarket straps provided the lug width is 16mm. Choose established manufacturers that guarantee aesthetic and constructional finish equal to the original Rolex. An artisanal strap in fine leather, custom-made, is not only compatible but often enhances the watch's visual identity, offering personalisation and uniqueness.
How long does a leather strap last on a Rolex Datejust 31?
Durability depends on leather quality, daily use and maintenance. A quality alligator or calf strap typically lasts 3–5 years with regular use. Vegetable-tanned leather, more eco-conscious, requires greater care but develops a beautiful patina over time. Natural leather ages elegantly: creasing and colour nuances are not defects but evidence of the watch's history. We recommend having the strap refurbished every 2–3 years by a specialist laboratory.
