FAQ

What is the lug width of the Rolex Datejust 31 278248-0029?

The lug width of the Rolex Datejust 31 278248-0029 is 16 millimetres. This is a non-standard dimension specific to this lady's model. To verify correct measurement, place a digital calliper between the two metal shoulders of the strap attachment seat: the value must be exactly 16mm.

Which strap pairs best with a yellow gold Datejust 31?

To enhance the luminosity of the 18-karat yellow gold, we recommend natural brown <a href="/pages/termine-glossario/alligatore">alligator</a> or vegetable-tanned calf leather. Alligator creates an elegant contrast through its large grain texture and developing patina, whilst calf offers a silky tactile sensation and colour depth that evolves over time. Both materials maintain the precious nature of the case without visually weighing down the wrist.

How do you change the strap on a 31mm Rolex Datejust 31?

To change the strap on a 31mm Datejust 31, you require a spring bar tool. Position the watch on a soft surface. Insert the flat tip of the tool into the small slot beneath the lug, gently lift the spring pin towards the watch body to release it, then extract the strap. Repeat on the other side. To install the new strap, align the holes with the lugs and press the spring pin until it clicks into place. Avoid excessive force, which could damage the delicate lugs.

Are aftermarket 16mm straps compatible with the Rolex Datejust 31 278248-0029?

Yes, any artisanal 16mm strap with correct lug width is fully compatible with the Datejust 31 278248-0029. Verify that the strap has been handcrafted specifically for this width and that the buckle or <a href="/pages/termine-glossario/deployante">deployant clasp</a> is slim enough to avoid discomfort on the wrist. Choose suppliers who respect millimetre tolerances, as small deviations can compromise the visual quality of the pairing.

How long does a leather strap last on a daily-wear watch?

A high-quality leather strap, handcrafted using natural leathers such as <a href="/pages/termine-glossario/alligatore">alligator</a> or vegetable-tanned calf, typically lasts between 3 and 5 years with daily wear and proper maintenance. Longevity depends on sun exposure, humidity, perspiration and frequency of use. To extend strap life, avoid salt water, dry immediately after liquid contact and periodically rotate between multiple straps. Luxury straps develop patina over time, which increases their aesthetic value.
