Frequently asked questions
What is the lug width of the Rolex Datejust 36 reference 116231-0089?
The Rolex Datejust 36 reference 116231-0089 features a standard lug width of 20 millimetres. This dimension is inherent to the 36mm case design and integrated lugs. When replacing the strap, it is essential to ensure the new strap is specifically sized for 20mm to guarantee proper installation and balanced aesthetic proportions.
Which strap material is best suited for the bicolour Datejust 36?
For the Datejust 36 116231-0089 in rose gold and stainless steel, alligator or Nile crocodile leather represents the most sophisticated choice, offering linear texture and softness that elegantly contrasts the metallic case. Vegetable-tanned calf leather is excellent for those seeking natural patina development over time. Shell cordovan delivers superior density and lustre, whilst fluoroelastomer rubber is ideal for daily wear in humid environments.
How do I change the strap on a Rolex Datejust 36?
Changing a Datejust 36 strap requires precision. Position the watch with lugs facing upward and use a specialized pin remover tool designed for Rolex watches. Insert the tool's tip into the small hole on the interior shoulder of the lug and apply gradual pressure to extract the metal pin. Once removed, the old strap slides away from the case. For installation of the new strap, align the holes and reintroduce the pin with uniform pressure until it locks into place. If you lack the correct tool, consult a qualified watchmaker to prevent case damage.
Can I use an aftermarket strap on a Rolex Datejust 36?
Yes, a Rolex Datejust 36 can be paired with quality aftermarket straps, provided the lug width is precisely 20 millimetres and the buckle or deployante width is compatible with the case. Specialist brands such as milanostraps.it offer bespoke artisanal straps crafted specifically for Rolex watches, ensuring construction excellence and finishing equivalent to official Rolex straps. A customised artisanal strap can enhance the watch and reflect the owner's personality.
How long does a leather strap last on a Rolex Datejust 36?
Leather strap longevity depends on material quality, usage patterns and maintenance. A high-grade alligator or shell cordovan strap can last 5-7 years with daily wear and proper care (regular cleaning, prompt drying after water contact, annual conditioning). Vegetable-tanned calf develops visible patina after 2-3 years of use with similar lifespan. Fluoroelastomer rubber is more durable, lasting 8-10 years. Factors such as humidity, perspiration and sun exposure accelerate wear. Casati Milano provides an 18-month warranty on manufacturing defects for bespoke straps.
