The Daytona 6241, seen from the bench

The Rolex Daytona 6241 is a wristwatch chronograph produced between 1966 and 1969, representing a pinnacle of 1960s watchmaking. It features a stainless steel case measuring approximately 36 mm in diameter with a distinctive black or white resin bezel with tachymetric scale. The watch is powered by the manual Valjoux 727 movement, a column-wheel chronograph caliber. The lug width measures 19 mm, a non-standard size requiring precise strap selection for optimal fit and aesthetics.

Frequently asked questions

What is the lug width of the Rolex Daytona 6241?

The Rolex Daytona 6241 has a lug width of 19 mm. This is a non-standard measurement compared to the 20 mm found on later Daytona references, so it is essential to verify this dimension before purchasing an aftermarket or replacement strap.

What is the best strap for the Rolex Daytona 6241?

For the Daytona 6241, straps in vegetable-tanned alligator or aged calf leather are the most coherent choices given the watch's vintage character. Shell cordovan is recommended for those seeking greater compactness and longevity. For a more sporting use, NATO or vulcanised rubber straps are valid functional alternatives.

How do you change the strap on a Rolex Daytona 6241?

To replace the strap on the Daytona 6241, a fine-tipped springbar tool is required to remove the spring bars securing the strap within the lugs. It is advisable to work on a padded surface to avoid scratching the case, and to measure the lug width precisely — 19 mm — before fitting the new strap.

Are there aftermarket straps compatible with the Rolex Daytona 6241?

Yes, aftermarket straps are available specifically made for the 19 mm lug width of the Daytona 6241. Milano Straps produces bespoke handcrafted straps compatible with this reference, available in various materials and colours. It is important that the strap respects the 19 mm attachment width and tapers towards the buckle in keeping with the original proportions.

How long does a leather strap last on a Rolex Daytona 6241?

The lifespan of a leather strap depends on the material, daily care, and intensity of use. A quality alligator or shell cordovan strap, treated periodically with appropriate conditioners and kept away from excessive moisture, can last between 3 and 7 years whilst maintaining good structural integrity. Vegetable-tanned calf leather develops a patina over time but is more susceptible to water and perspiration.
