Strap for Cellini Time Everose / White / Alligator Brown

The lug width of the Rolex Cellini 50505-0010 is exactly 20 millimetres. This specific measurement is determined by the proportion between the case diameter (39 mm) and the case lug geometry. To verify this measurement with precision, remove the original strap and measure the distance between the two pins (spring bars) that pass through the lugs: the value must be exactly 20 mm. All compatible aftermarket straps must have this measurement to ensure perfect fit.

For the Cellini 50505-0010 in 18k rose gold, the most suitable materials are alligator (in dark brown or cognac tones), vegetable-tanned calf leather, and shell cordovan. Alligator is the natural formal choice, as its grain pattern dialogues elegantly with the patina of rose gold. If you prefer organic ageing, vegetable-tanned calf leather offers visible history over time. Shell cordovan represents the ideal compromise between formality and durability, with a lustre that emerges naturally with use.

The strap on the Cellini 50505-0010 is removable through the pins (spring bars). Using a dedicated tool (spring bar tool), gently compress the pin from one end, lift the strap away from the case and fully remove the pin. Reverse the procedure with the new strap: insert the pin, align the strap with the case lugs and press until it locks. Ensure the pin is completely inserted and secured before wearing the watch. If you are unsure, consult a certified Rolex watchmaker.

Yes, an aftermarket strap is compatible with the Cellini 50505-0010 provided it has a lug width of 20 millimetres. Compatibility is guaranteed by mechanical measurement: 20 mm pins on the strap will fit perfectly into the case lugs. A bespoke atelier such as Casati Milano produces personalised 20 mm straps according to your aesthetic specifications, with premium leathers (alligator, calf, cordovan) and an 18-month guarantee on manufacturing defects.

The lifespan of a leather strap depends on frequency of use, material quality and storage conditions. A high-quality alligator or cordovan strap, worn daily, maintains structural and functional integrity for 4–7 years before replacement is necessary. Vegetable-tanned calf tends to last slightly less (3–5 years) because vegetable tanning is less resistant to mechanical wear, but aesthetic ageing is part of its charm. To extend lifespan, avoid prolonged exposure to humidity, direct sunlight and aggressive cleaning agents. A Casati Milano strap, crafted from noble materials with meticulous construction, ensures superior longevity thanks to internal reinforcement details.
