The dial displays day and date windows with champagne background and applied Roman numerals or indices in gold.

Frequently asked questions

What is the lug width of the Rolex Day-Date 36 118135-0082?

The Rolex Day-Date 36 118135-0082 features a lug width of 20 millimetres. This dimension was engineered by Rolex to maintain harmonious proportions between the 36 mm case and the strap, avoiding visual over- or under-sizing. Lug width is measured between the two case lugs.

Which strap material is recommended for the Day-Date 36 118135-0082 in rose gold?

For the Day-Date 36 118135-0082, the finest choices are alligator in cognac or dark brown, or shell cordovan. Both complement the warmth of Everose gold superbly. Alligator delivers formal elegance with geometric grain; cordovan evolves over time, developing unique patina. Vegetable-tanned calf offers solid durability and practicality. For a sportier interpretation, black or navy NATO canvas creates striking chromatic contrast with the rose gold.

How do you change the strap on a Rolex Day-Date 36?

The Day-Date 36 uses fixed lugs without removable spring bars as on classical models. A spring bar tool is required to compress the internal spring mechanism at the lugs and extract the old strap. Insert the new strap, aligning it perfectly with the lug attachments and ensuring there is no lateral play. We recommend having this operation performed by an authorised Rolex dealer or skilled watchmaker to prevent case damage.

Is an aftermarket 20 mm strap compatible with the 118135-0082?

Yes, provided the lug width is precisely 20 millimetres as measured between the lugs. A quality artisan strap manufactured to this specification is fully compatible. Verify that the strap exhibits no lateral play in the lugs and that the buckle or deployante clasp is proportionate to the case. Construction quality must reflect the nobility of the timepiece itself.

How long does a leather strap last on a Rolex Day-Date 36?

Longevity depends on material and wear patterns. An alligator strap typically lasts 4-5 years with daily use. Shell cordovan, being denser and oil-rich leather, can exceed 7-8 years. Vegetable-tanned calf lasts approximately 6-8 years. Decisive factors include exposure to perspiration, moisture, and frequency of use. Regular maintenance—wiping with a damp cloth, air-drying, and annual conditioning—significantly extends strap life.
