Santos Ronde, Steel & Gold, Automatic

How to tell it apart

What separates a Ref. 1910 from its neighbors, and what to check before you buy or sell one.

What is a Cartier Santos Ronde Ref. 1910 worth?

Public auction and dealer results for Ref. 1910 from November 2021 to November 2026 (five years, as the last three alone have too few) come to $1,750 to $2,050, with a median of $1,750 across 3 sales of this exact reference. The most recent was $1,750 at Bonhams London in May 2023. Condition, service history, and the original box and papers move an individual watch within that range.

What is the Santos Ronde Ref. 1910?

The two-tone Santos Ronde: a 33 mm round case in stainless steel with an 18k yellow gold bezel, a white dial with black Roman numerals and a date at 3 o'clock, blued steel sword hands, a sapphire crystal and a steel and 18k gold bracelet with a folding clasp. It is automatic: Bonhams catalogs the movement as the 21-jewel Cal. 049. Sotheby's catalogs the watch as Reference 1910 Santos Ronde.

How does the 1910 differ from the steel Ref. 1920-1?

Metal. Both are 33 mm automatic Santos Rondes with a date at 3 o'clock. The 1910 combines stainless steel with 18k yellow gold on the case and bracelet; the 1920-1 is the all-steel version.

What should I check before buying a Ref. 1910?

The case back first: it should carry the reference and a case number, and Sotheby's records the back secured by eight screws and the case, dial and movement all signed. Then check that the date at 3 o'clock changes cleanly, that the automatic winds and keeps time, that the steel and gold bracelet has no stretch or missing links, and that the folding clasp closes firmly. Look at the gold parts for wear or heavy polishing.
