Strap for Rolex Day-Date 36 118206

The lug width of the Rolex Day-Date 36 118206 is 20 millimetres. This measurement represents the distance between the horizontal lugs of the case where the strap is inserted. To verify compatibility, measure the net space between the two lugs without including the case thickness itself. All straps in our catalogue for 20mm lug width are fully compatible with this platinum model.

For the 118206 in platinum, we recommend black or dark brown alligator for formality, or vegetable-tanned shell cordovan for those seeking natural patina and character over time. Grey-pearl vegetable-tanned calf is ideal for those desiring daily versatility. The choice of material depends on personal style and occasion: the platinum's natural grey tone dialogues elegantly with restrained colour palettes and satin lustre.

Strap replacement is performed by removing the spring bars that connect the strap to the case. Use a dedicated tool or a gentle lever instrument to slightly compress the bars and slide the strap from the lugs. Once the bars are freed, insert the new strap by aligning the holes with the case lugs and secure the bars until they click. It is a straightforward operation, but we advise caution to avoid scratching the platinum. Casati Milano also offers a strap replacement service at our atelier by appointment.

Yes, it is possible to use quality aftermarket straps provided they respect the 20mm lug width. MilanoStraps produces artisanal leather straps specifically compatible with the Day-Date 36, featuring fine materials such as alligator, shell cordovan, and calf. Each strap is handcrafted in Italy with careful leather selection and finishes consistent with your watch's quality level. We recommend avoiding generic low-quality straps, as they would diminish the aesthetic of platinum.

The lifespan of a leather strap depends on the material and usage frequency. A quality alligator strap worn daily with care typically lasts 3–5 years before replacement is needed. Shell cordovan with vegetable tanning tends to last longer (5–7 years) due to the more resilient fibre and develops a desirable patina. MilanoStraps provides an 18-month warranty on manufacturing defects; however, longevity also depends on sun exposure, humidity, and frequency of use. Regular maintenance—gentle cleaning and proper drying—significantly extends the strap's useful life.
