Day-Date 36 118389-0061— lug 20mm

The lug width of the Rolex Day-Date 36 118389-0061 is 20 millimetres. This measurement specifies the space between the two lugs of the case where the strap attaches via spring bars. It should not be confused with the total length of the strap itself.

For the white gold Day-Date 36, alligator leather remains the most coherent choice with Rolex tradition, offering natural texture and formal elegance. Alternatively, vegetable-tanned calf leather guarantees comfort and softness, whilst FKM rubber is ideal for contemporary versatility between formal and casual occasions.

The process requires a pin removal tool. Position your watch on a soft support, locate the two lateral pins at the lugs, insert the tool into the central hole of the pin and apply gentle pressure to extract it. Once the pin is removed, the old strap detaches. Insert the new strap, reintroduce the pin from the opposite side and verify it is securely locked. If you are not experienced, consult a Rolex service centre or a professional watchmaker.

Yes, it is entirely possible and recommended. A quality aftermarket strap allows you to personalise your watch according to your style, combining materials such as alligator, calf, shell cordovan or FKM rubber. Ensure your supplier guarantees compatibility with the 20mm lug width and uses Rolex-grade spring bars to avoid damaging the case.

The lifespan of a leather strap depends on use, tanning method and maintenance. With vegetable tanning and average wear, expect 4–6 years before significant leather degradation. Chrome-tanned leather typically lasts 7–8 years. FKM rubber maintains optimal performance for 5–7 years. Regular maintenance (cleaning, protection from stagnant water) significantly extends strap lifespan.
