Frequently asked questions
What is the lug width of the Rolex Day-Date 36 reference 118135-0063?
The lug width of the Rolex Day-Date 36 reference 118135-0063 is 20mm. This measurement – the space between the lugs where the strap attaches – is standard across all modern Day-Date 36 models. Always verify the lug width with a digital calliper before ordering an aftermarket strap to ensure absolute compatibility.
Which strap should I choose for the Day-Date 36 118135-0063 in rose gold?
For the 118135-0063 in Everose, the most suitable materials are alligator (regular scales amplify the rose gold's luminosity), vegetable-tanned calf leather (coarse grain, natural patina over time), shell cordovan (unequalled durability and lustre) and FKM rubber (sporty functionality). Your choice depends on usage: alligator for formal occasions, vegetable-tanned calf for elegant daily wear, cordovan for collecting, rubber for aquatic versatility.
How do I change the strap on a Rolex Day-Date 36?
Changing the strap requires a spring bar tool (double-pronged implement) to compress the attachment pins. Position your Rolex on a soft surface, insert the tool's tip into the pin aperture and press until the internal spring releases, then extract the old strap. Repeat on the other side. Insert the new strap by aligning the holes with the lugs and allow the pins to engage naturally. If you lack confidence, consult an authorised Rolex dealer to ensure precision and prevent case damage.
Can I use an aftermarket strap on my Day-Date 36 118135-0063?
Yes, provided the strap is designed for 20mm lug width. Quality aftermarket straps – particularly artisanal ones – frequently surpass original Rolex straps in material selection, aesthetic customisation and leather longevity. We recommend choosing specialised suppliers who understand the importance of constructive precision and chromatic compatibility with Everose.
How long does a leather strap last on a watch like the Day-Date 36?
A quality leather strap (alligator, vegetable-tanned calf, cordovan) typically lasts 3-5 years with daily wear, with variation depending on personal perspiration, sun exposure and frequency of wear. Vegetable-tanned leather ages elegantly and can last 7+ years with proper care. Cordovan is renowned for durability extending 10-15 years. Factors shortening lifespan include frequent water immersion, direct application of alcohol and perfumes to the leather, and lack of post-perspiration drying. Minimal maintenance (periodic drying) significantly extends strap life.
