Strap for Rolex Sea-Dweller 16660 Comex Matte

The Rolex Sea-Dweller 16660 Comex Matte features a lug width of precisely 20 millimetres. This dimension is determined by the distance between the case lugs where the strap attaches. To verify, place a calliper on the inner side of the case lug: the measurement must be exactly 20 mm to ensure strap compatibility and proper suspension of the watch on the wrist.

The optimal choice depends on intended use. American or Nile alligator offers maximum aesthetic nobility and decade-long durability, with natural texture creating refined contrast against the steel case. Vegetable-tanned calfskin represents the most characterful option, developing a golden patina over time. Shell cordovan provides compactness and increasing luminosity. Vulcanised rubber remains the purely functional choice if the watch continues to encounter aquatic or nautical environments.

The operation requires a specific tool, known as a strap remover or lug tool. Place the watch on a soft cloth with the case facing upward. Insert the flat tip of the tool under the separation button located inside the lug, pushing gently outward until the button disengages. Repeat on the other side. Subsequently, insert the new strap by aligning the holes with the buttons and press until the locking click is heard. If uncertain, entrust the operation to a professional watchmaker.

Yes, provided the lug width is precisely 20 mm. Many artisanal manufacturers, including Casati Milano, produce high-quality aftermarket straps specifically designed for this lug width. The essential requirement is always to verify compatibility with the watch reference and strap dimensions before purchase. A quality aftermarket strap can equal or exceed the durability of original Rolex equipment.

A quality artisanal leather strap, crafted from alligator, vegetable-tanned calfskin or shell cordovan, guarantees a lifespan of 5-8 years of regular daily use. Longevity depends on humidity exposure, perspiration, frequency of use and maintenance. With an 18-month guarantee on manufacturing defects, a Casati Milano strap represents a durable investment. Periodic treatment with leather-specific oils significantly extends the strap's useful life.
