The Day-Date 36 118205f-0114, seen from the bench

The Rolex Day-Date 36 in Everose gold (ref. 118205f-0114) exemplifies classical watchmaking mastery in 36mm format. Introduced in the 1950s as a status symbol, it features simultaneous day and date display on the dial, paired with elegant proportions and a solid precious metal case. The technical heart is the Rolex caliber 3155, a self-winding mechanical movement beating at 28,800 vibrations per second with approximately 48 hours power reserve, certified chronometer with Chronergy escapement. The 36mm rose gold 18k case features a 20mm lug width, sapphire crystal, and sealed caseback for maximum water resistance.

Frequently asked questions

What is the lug width of the Rolex Day-Date 36 ref. 118205f-0114?

The lug width of the Rolex Day-Date 36 118205f-0114 is 20 millimetres. This is the gap between the two lugs of the case where the strap is attached. When purchasing a replacement strap, always verify that the spring bar passage is calibrated to 20mm to ensure a perfect fit without any play.

Which strap material is recommended for this Rolex Day-Date 36?

For the Day-Date 36 in rose gold, we primarily recommend alligator: the regular grain and natural colour create visual harmony with the warmth of the gold. Alternatively, vegetable-tanned calf leather ages beautifully, developing a patina that enhances the character of the timepiece. Shell cordovan is also an excellent choice for those who appreciate noble leathers that improve over time.

How do you change the strap on a Rolex Day-Date 36 118205f-0114?

The process is straightforward: position the watch on a soft cloth with the caseback facing upwards. Locate the spring bar (small metal pin) that passes through the lug. Using a dedicated tool or small screwdriver, gently push the spring bar to extract it. Once removed, the old strap slides off easily. Insert the new strap by aligning the passage holes with the spring bar, then reinsert the pin. If uncertain, consult a specialist watchmaker or Casati Milano.

Is an aftermarket strap compatible with the Rolex Day-Date 36 ref. 118205f-0114?

Yes, any strap with a 20-millimetre passage is compatible with the Day-Date 36 118205f-0114. However, to preserve the quality of the timepiece, we advise against generic straps: prioritise manufacturers specialising in natural leather and artisanal construction. On milanostraps.it you will find a curated selection of 20mm straps chosen for quality and aesthetics, many customisable with Casati Milano.

What is the average lifespan of a leather strap for this model?

A high-quality leather strap (alligator, calf, shell cordovan) with moderate daily use typically lasts 3 to 5 years before showing visible wear. Longevity depends on factors such as humidity, sun exposure, maintenance and frequency of use. A well-maintained strap stored in dry conditions can last over 7 years. milanostraps.it and Casati Milano offer replacement and restoration services for worn straps.
