Strap for Datejust 31 Rose Gold / Domed / Rose - Diamond / President

The Datejust 31 Ref. 278245-0030 features a fixed lug width of 16 millimetres. This measurement is determined by the integrated lugs on the Everose gold case and cannot be modified. Correct measurement is obtained using a digital calliper from the centre of one spring bar to the other, without compression. It is essential to verify this measurement before purchasing any aftermarket strap to ensure compatibility.

For the Datejust 31 in Everose gold, the ideal strap is alligator leather with vegetable tanning (tobacco brown, black, or burgundy). Alligator offers a refined texture and develops a natural patina that enhances the warmth of rose gold. Shell cordovan is an excellent alternative, prized for its density and intrinsic lustre. Aniline calf or fine grain leather remains a classic choice for those seeking a smooth surface and understated elegance. NATO straps and rubber are inadvisable, as they undermine the refined DNA of the model.

The strap is changed by removing the spring bars from the lateral lugs using a dedicated spring bar tool. Insert the tip of the tool into the slot of the spring bar, lift slightly whilst compressing the bar, then extract the barend from the lug. Repeat on the opposite side. Insert the spring bars of the new strap into the same lugs, ensuring the strap is centred on the case. If inexperienced, consult a certified Rolex watchmaker.

Yes, provided the strap is constructed specifically for a 16-millimetre lug width. Quality aftermarket straps in alligator, calf, or shell cordovan are fully compatible. We recommend confirming with the manufacturer that the strap has been tested on the Datejust 31. Avoid generic 16mm straps without verification: precision is paramount on a precious case such as Everose gold.

Longevity depends on material, usage, and maintenance. A vegetable-tanned alligator strap of high quality, with regular care (cleaning every six months, conditioning annually), will last 4–7 years of daily wear. Shell cordovan is more durable, lasting 8–10 years. Aniline calf requires more frequent maintenance and typically lasts 3–5 years. Leather deteriorates through wrist friction, perspiration, and sun exposure. Replacing the strap every 4–5 years is recommended practice to preserve the aesthetic integrity of the timepiece.
