Strap for Oyster Perpetual 36 White Grape

The lug width is 20 millimetres. This measurement is factory-standardised by Rolex and represents the distance between the lugs where the strap is attached. It is critical to verify this measurement before purchasing an aftermarket strap, as an incorrect lug width (for example, 22 mm) will not fit the attachment mechanisms properly.

Premium alligator represents the most formal choice, offering a distinctive grain pattern and a patina that evolves over time. For a balance between elegance and everyday wearability, vegetable-tanned calf leather guarantees initial softness and progressive durability. Shell cordovan is ideal for those seeking superior longevity and natural lustre. For a more sporty aesthetic, high-density natural rubber or NATO straps in Cordura offer versatility and thermal comfort.

Changing the strap on this model requires specific tools: a small flat-head screwdriver or, ideally, a professional spring bar tool. Position the watch in a stable holder, locate the small groove on the lugs, and gently push the elastic pin towards the opposite side, sliding it out of the lug. Repeat for the other side. Insert the new strap by aligning the elastic pin with the grooves and pushing until it clicks into place. We recommend entrusting this operation to professionals to avoid damage to the case.

Yes, provided the strap is specifically dimensioned for 20-millimetre lugs. Quality aftermarket straps — crafted from alligator, calf, shell cordovan, or rubber — are fully compatible with this model. However, it is essential to verify that the strap has been engineered for this exact lug width and that it is supplied with the correct spring bars. Avoid inexpensive universal straps that use insufficiently rigid pins.

Longevity depends on material, usage, and maintenance. A premium alligator strap has an average lifespan of 5–7 years with daily wear. Vegetable-tanned calf typically lasts 4–6 years. Shell cordovan, being denser, can exceed 10–15 years if maintained correctly. High-quality natural rubber retains its properties for 6–8 years. The frequency of strap replacement also depends on humidity, prolonged sun exposure, and maintenance quality (periodic cleaning, conditioning).
