FAQ
What is the lug width of the Rolex Datejust 36 116231-0071?
The Rolex Datejust 36 reference 116231-0071 is fitted with 20-millimetre threaded lugs. This measurement is taken internally between the two spring bar holes and is the standard for the modern Datejust 36. It is not compatible with straps designed for 19mm or 21mm lug watches. Always verify compatibility before purchase.
What is the best strap for the Rolex Datejust 36 116231-0071?
The choice depends on usage and aesthetic preference. For formal elegance, a dark brown or cognac alligator strap enhances the warmth of the rose gold in the two-tone case. For restraint, vegetable-tanned calf offers consistent texture and natural patina development. Shell cordovan represents the premium option for mirror-like patina and extraordinary durability. We recommend consulting Casati Milano to select the leather and colour according to your daily wear pattern.
How do I change the strap on the Datejust 36 116231-0071?
The 116231-0071 is fitted with threaded spring bars. Obtain a spring bar tool (small slotted screwdriver or dedicated key). Insert the tip into the lateral hole of the spring bar until the terminal retracts, then extract the old strap. Repeat on the other side. Install the new strap by aligning the terminals with the holes and pressing gently until it clicks. Avoid forcing to prevent damage to the Oyster case.
Can I use an aftermarket strap compatible with the Datejust 36 116231-0071?
Yes, provided it is certified 20mm lug width and constructed from quality materials (alligator, calf, shell cordovan). Artisanal straps from Casati Milano guarantee precise compatibility and finishes synchronised with the two-tone case (rose gold and stainless steel). Always verify measurements and prefer manufacturers specialising in luxury watches to avoid misalignment or accelerated wear.
How long does a leather strap last on the Rolex Datejust 36 116231-0071?
A quality leather strap (alligator, calf, shell cordovan) typically lasts 3–5 years with moderate daily wear. Longevity depends on tanning method (vegetable tanning ages better), environmental humidity, frequency of use and maintenance. Keep the leather dry, avoid prolonged exposure to direct sunlight and moisture, and occasionally apply specific conditioner for watches. Casati Milano guarantees 18 months against manufacturing defects.
