Frequently asked questions
What is the lug width of the Rolex Datejust 31 278241-0016?
The lug width of the Rolex Datejust 31 reference 278241-0016 is 16 millimetres. This measurement must be verified using a digital calliper, measuring perpendicular to the spring bars. A 16mm lug width is specific to the ladies' 31mm Datejust models and is not compatible with universal straps. Ensure that any ordered strap is certified for this exact width specification.
Which strap is recommended for the Rolex Datejust 31 278241-0016?
For the Datejust 31 two-tone steel and Everose gold 278241-0016, we recommend straps in black or brown alligator, or Nile calf in cognac and bourbon tones. Alligator amplifies the visual richness of rose gold through its natural grain texture and wear resistance. For daily versatility, vulcanised rubber in grey or black offers practicality whilst maintaining elegance. Avoid synthetic NATO straps: their informality contrasts with the model's inherent refinement.
How do I change the strap on the Rolex Datejust 31 278241-0016?
Remove the strap using a spring bar tool or equivalent instrument. Position the watch on a soft surface. Gently depress the spring bar from one side to extract it, then lift the strap away. Repeat for the opposite side. Insert the new strap by threading the spring bar into the lug hole, ensuring it clicks fully into position. Rolex spring bars have a 1.8mm diameter: verify that your new strap accepts this tolerance. If uncertain, consult a certified watchmaker.

How long does a leather strap last on the Rolex Datejust 31 278241-0016?
A premium leather strap typically lasts 3–5 years with daily use and regular maintenance. Alligator offers the greatest longevity thanks to its natural scale structure; calf leather typically lasts 3–4 years whilst developing a beautiful patina. Vulcanised rubber resists up to 7–10 years. Lifespan depends on climate exposure, frequency of rotation and tanning method. Milano Straps straps include an 18-month warranty against manufacturing defects. We recommend rotating at least two straps to extend operational life.
