Strap for Rolex Datejust 1602

The Rolex Datejust 1602 features a consistent 20mm lug width across its entire production run (1959–1977). This measurement remains unchanged regardless of dial configuration or original bracelet choice. When replacing the strap with an aftermarket option, it is advisable to check the lug curvature as well, since curved ends are required for a proper fit against the Oyster case.

For a stainless steel Datejust 1602, an alligator strap with vegetable tanning is the most coherent choice given the watch's formal character. The square-scale grain complements the fluted bezel naturally. For everyday use, smooth calf leather in black or brown is more hardwearing and develops patina over time. A nylon NATO strap suits casual or sporting contexts, while vulcanised rubber is ideal for water use, preserving the Oyster case's water resistance.

To replace the strap or bracelet on a Datejust 1602, a springbar tool is required. The spring bars connecting the strap to the case lugs are of standard diameter: compressing the ends of the bar inward releases the strap. Care should be taken to avoid scratching the case. If in doubt, it is advisable to consult a watchmaker or the Casati Milano atelier for a professional strap change.

Yes. The Datejust 1602 accepts any strap with a 20mm attachment and curved ends to fit the Oyster case profile. The aftermarket offers options in leather, rubber, nylon and metal. Milano Straps produces handcrafted 20mm straps with curved ends specifically designed for Rolex Oyster cases, available in numerous leather and buckle combinations.

The lifespan of a leather strap depends on the material, tanning method and maintenance. A vegetable-tanned alligator strap, if treated with a neutral leather cream and kept away from excessive moisture, can last between three and seven years with daily wear. Calf leather tends to have a slightly shorter lifespan but offers greater resistance to perspiration. Milano Straps provides an 18-month guarantee on manufacturing defects for all its straps.
