The Datejust 41 126301-0004, seen from the bench

The Rolex Datejust 41 Rolesor Everose ref. 126301-0004 combines Rolex's iconic automatic date function with a two-tone case of Everose gold and 904L steel. The 41 mm case houses the COSC-certified caliber 3235 movement, featuring a niobium-zirconia Parachrom hairspring and silicon nitride escapement wheel for enhanced stability and antimagnetism up to 1500 Gauss. With a 70-hour power reserve and lug width of 21 mm, this Datejust represents the balance between formal elegance and contemporary versatility.

Frequently asked questions

What is the lug width of the Rolex Datejust 41 ref. 126301-0004?

The lug width of the Datejust 41 ref. 126301-0004 is 21 millimetres. This measurement is standard across all modern Datejust 41 models and represents the optimal compromise between structural rigidity and strap-changing flexibility. To measure correctly, insert callipers directly into the lug seats on the case, measuring from inside to inside.

Which strap material is recommended for the Datejust 41 in Everose and steel?

For the Everose and steel bicolour case of the 126301-0004, we recommend alligator straps in black or dark brown for maximum formality, or vegetable-tanned vitello in cognac or bordeaux to complement the rose gold. Alligator in vegetable tanning is the classic choice, whilst shell cordovan offers superior resistance to wear. For more sportive applications, a steel or brown NATO strap integrates the versatility of the 41mm case without compromising elegance.

How do you change the strap on a Rolex Datejust 41?

The Datejust 41 uses a standard Rolex deployante clasp, removable manually by pressing the small lateral levers that disengage the articulation pin. To change the strap, remove the deployante from the original strap, insert the new strap through the case lugs ensuring the keeper is centred, then remount the deployante by tightening the lateral pins. Alternatively, Casati Milano offers professional strap-changing services at its Milan atelier by appointment.

Is an aftermarket 21mm strap genuinely compatible with this watch?

Yes, any strap with a 21-millimetre lug width is compatible with the 126301-0004, provided the base curve is appropriate. However, Rolex employs precise anatomical curves in its own straps. A bespoke artisanal strap, such as those crafted by Casati Milano, is calculated specifically for the Datejust 41, ensuring perfect curve at the lugs, balanced load distribution, and visual coherence with the wearer's wrist anatomy.

How long does a natural leather strap last on a Rolex Datejust 41?

The lifespan of a natural leather strap depends on frequency of wear, humidity levels, and maintenance practices. A high-quality artisanal alligator or vitello strap, worn daily on a Datejust 41, typically offers 4-6 years of service before requiring regeneration or replacement. Vegetable-tanned leather ages exceptionally well, developing a rich patina that extends aesthetic appreciation. Casati Milano guarantees its straps for 18 months against manufacturing defects and offers regeneration and lug-replacement services by appointment.
