Strap for Cellini Time White Gold / Black / Alligator Black

The Rolex Cellini 50509-0006 features a lug width of 20 millimetres. This technical specification defines the distance between the two metal lugs protruding from the watch case. Any strap with a 20mm lug width is perfectly compatible with this model.

For the Cellini 50509-0006 in white gold, genuine alligator and shell cordovan are the ideal materials. Alligator provides formal contrast through its distinctive grain pattern; shell cordovan develops a profound patina that references classical dress watch heritage. Vegetable-tanned calf leather offers an excellent contemporary interpretation.

Strap replacement requires: 1) a spring bar tool; 2) positioning the watch on a stable surface; 3) applying gentle downward pressure to one lug pin whilst sliding it out; 4) repeating on the opposite side; 5) carefully threading the new strap by aligning the pins with the lug holes. A straightforward procedure requiring precision and care.

Bespoke artisanal straps crafted from certified leather—alligator, shell cordovan, vegetable-tanned calf—guarantee superior quality versus mass-market alternatives. Specialist providers such as Casati Milano offer direct stylistic consultation, monitor the manufacturing process, and provide warranty against production defects. An elite handcrafted 20mm strap lasts 6-8 years with rotation, compared to 2-3 years for generic alternatives.

A premium leather strap (alligator, shell cordovan) with daily wear typically lasts 4-5 years before the tanning loses structural integrity. With rotation across 2-3 straps, lifespan extends to 7-8 years. Wear factors include: humidity exposure, buckle rotation frequency, and sun exposure. Periodic maintenance—gentle cleaning and leather conditioning—substantially extends strap longevity.
