Frequently asked questions

What is the lug width of the Rolex Day-Date 36 118205f-0061?

The lug width of the Rolex Day-Date 36 reference 118205f-0061 is 20 mm. This measurement is taken with a digital calliper positioned between the inner faces of the two lugs, close to the bezel. It is the correct measurement for selecting any compatible aftermarket strap.

What is the best strap for the Rolex Day-Date 36 118205f-0061?

For the rose gold case of the Day-Date 36 118205f-0061, the most suitable materials are alligator leather in cognac or burgundy tones and natural shell cordovan, both of which complement the warm hue of the rose gold. For less formal settings, a shaped rubber strap maintains chromatic coherence and offers high wearing comfort.

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

The strap on the Rolex Day-Date 36 is secured to the lugs via standard 20 mm spring bars. To replace it, use a spring bar tool or a fine fork-shaped lever: compress the spring bar on one side, release the lug, then repeat on the other side. It is advisable to work on a soft surface to avoid scratching the rose gold case.

Are there aftermarket straps compatible with the Rolex Day-Date 36 118205f-0061?

Yes. Any strap with a 20 mm attachment and slightly curved ends is compatible with the Rolex Day-Date 36 118205f-0061. Milano Straps offers handcrafted straps in alligator, shell cordovan, calf leather and rubber with buckle or deployant clasp, made with pre-formed ends to fit correctly to the case geometry.

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

The lifespan of a leather strap depends on the material, frequency of use and care. A quality alligator strap, kept away from prolonged moisture and treated periodically with leather conditioner, will typically last three to five years while retaining its structural integrity. Shell cordovan, due to the density of its fibres, tends to last longer and develops a distinctive patina over time.
