Strap for Rolex Cellini 50609RBR

The lug width of the Rolex Cellini 50609RBR is 20 mm. This dimension represents the internal space between the two horizontal pins of the case that hold the strap. It is essential to respect this measurement to ensure precise insertion into the lugs without forcing or lateral play.

For the Cellini 50609RBR we recommend straps in black, dark brown or tortoise alligator, or shell cordovan. These materials pair formal sobriety with tactile elegance and complement the refined aesthetic of the white gold 18 carat case. A strap with vegetable tanning also offers the advantage of a natural patina that evolves over time.

Changing the strap requires a specific tool (sprung bar tool) to compress the elastic pins that secure the strap to the case lugs. The operation should be performed on a protected surface, with care to avoid scratching the gold case. If you are not experienced, consult a professional watchmaker or a specialist such as Casati Milano.

Yes, the Cellini 50609RBR is compatible with any quality strap equipped with a 20 mm lug width. Artisan aftermarket straps, provided they are made from noble materials and with finishes consistent with the watch, adapt perfectly to the case pins. The perceived quality depends on the choice of leather and the precision of the construction.

The lifespan of a leather strap depends on use, climate and maintenance. A quality alligator or shell cordovan, with regular conditioning with specific products, maintains structural integrity for 8–12 years. A vegetable tanned calf typically lasts 5–8 years. With Casati Milano, every strap carries an 18-month warranty on manufacturing defects.
