Cartier Ronde Solo Automatic 36mm 2018 Watch

Q: What are the key specifications of this Ronde Solo?
A: It is a 36 mm stainless-steel model with an automatic movement, silvered opaline dial with Roman numerals, blued-steel hands, sapphire crystal and a beaded crown set with a synthetic spinel cabochon. Thickness is approximately 9.5 mm and water resistance is 3 bar (about 30 metres).

Q: Which movement does it use and what is the power reserve?
A: It uses Cartier’s calibre 049, an automatic movement based on the ETA 2892-A2 architecture, with an approximate power reserve of 42 hours.

Q: Does it have a date display?
A: Yes, the Ronde Solo Automatic in 36 mm features a date window at 3 o’clock.

Q: Is 36 mm suitable for my wrist?
A: 36 mm is a classic, versatile size that suits many wrists and works as a unisex option. The relatively slim profile and broad dial make it wear elegantly under a cuff while still offering good presence for everyday wear.

Q: Can I swim or shower with it?
A: No. With a 3 bar/30 metres rating, it is designed for daily life splashes only. Avoid showering, swimming or sauna use, and ensure the crown is fully pushed in around water.

Q: What strap size does it take and can I change it?
A: The lug width is 20 mm. You can fit most quality 20 mm straps. If you wish to use the Cartier folding clasp, choose a strap that is specifically compatible with deployant clasps and sized for this clasp. Switching to a steel bracelet requires model-specific end links and may not be available for every case; consult a Cartier boutique or specialist if desired.

Q: What kind of crystal does it have and how scratch-resistant is it?
A: It is fitted with a sapphire crystal, which is highly scratch-resistant for day-to-day wear. As with any watch, avoid hard impacts to protect the crystal and case.

Q: How should I care for the watch and how often should it be serviced?
A: Cartier advises periodic checks of water resistance and a functional check roughly every six years. Many owners service an automatic watch about every 5–8 years depending on use. Keep the crown secured, avoid strong magnets and extreme heat, and wipe the watch with a soft cloth after wear.
