FAQ

What is the lug width of the Rolex Daytona 1165994ru-0002?

The lug width of the Rolex Daytona 1165994ru-0002 is 20 millimetres. This measurement refers to the distance between the spring bar pins on the watch lugs. To verify, position a millimetre ruler perpendicular to the pins: the value must correspond to 20.0 mm with a tolerance of ±0.2 mm. Any strap with a 20 mm lug width will fit correctly into the Daytona without requiring mechanical adjustments.

What is the best strap for the Rolex Daytona 1165994ru-0002 in white gold?

For the Daytona 1165994ru-0002 in white gold, black alligator leather represents the pinnacle aesthetic solution: the natural grain of the leather reflects the boldness of the precious case and develops a fascinating patina over time. Alternatively, dark brown shell cordovan (Cognac vintage) creates a sophisticated dialogue and evokes the model's racing heritage. For more versatile approaches, black or brown calf leather offers uniform grain and daily practicality. The essential detail is selecting a strap equipped with a deployante (butterfly clasp) to protect the white gold from wear.

How do you change the strap on the Rolex Daytona 1165994ru-0002?

Changing the strap on the Daytona 1165994ru-0002 requires a specified tool (spring bar remover or fork-shaped tweezers) and a stable work surface. Position the watch in a watchmaker's vice with rubber protective pads. Use the spring bar remover to compress the pin at its base, then remove the previous strap from the lugs. Align the pins of the new strap (20 mm lug width) with the cavities on the lugs and reinsert by pressing until the click of engagement. Repeat the procedure on the other side. If inexperienced, consult a certified Rolex service centre: the procedure is straightforward but requires precision to avoid scratching the case.

Is there an aftermarket strap compatible with the Daytona 1165994ru-0002?

Yes. Any leather, rubber or specialised textile strap specified for 20 mm lug width is compatible with the Daytona 1165994ru-0002. Artisanal manufacturers such as Casati Milano produce custom 20 mm straps specifically tested on Rolex models, guaranteeing impeccable finishing and highest-quality materials (alligator, shell cordovan, vegetable-tanned calf). Aftermarket straps offer greater creative freedom and personalisation compared to Rolex equivalents, typically at lower price points. The 18-month manufacturing defect warranty provides equivalent protection.

How long does a leather strap last on the Rolex Daytona 1165994ru-0002?

The lifespan of a leather strap for the Daytona 1165994ru-0002 depends on the material, usage and care. Alligator leather (more resilient) offers longevity exceeding 5–7 years with moderate daily wear; shell cordovan, due to its density, reaches 4–5 years; calf leather (less dense) exhausts its primary aesthetic phase within 3–4 years. Body perspiration, direct solar exposure and humidity are factors that accelerate wear. A strap preserved in the absence of light, stable temperatures and controlled humidity can last decades without appreciable degradation. Regularly applying specific leather balms (not mineral oils) significantly extends the useful life of the material.
