What is a Cartier Santos Ronde Ref. 1920-1 worth?

Archiva has found two public sales of Ref. 1920-1 in the last three years: $1,000 at Lockdales in June 2026 and $2,200 at Dawsons in April 2026. Two sales are a rough guide, not a market price.

What is the Santos Ronde Ref. 1920-1?

The all-steel Santos Ronde: a 33 mm stainless steel case with screws on the bezel, a white dial with black Roman numerals and a date at 3 o'clock, blued steel sword hands, a sapphire crystal and an integrated steel bracelet with a deployant clasp. It is automatic, and dated examples run from the 1990s to about 2004. Antiquorum records the bezel and case back fixed with eight screws and the Cartier secret signature at 10 o'clock.

What movement is in the Ref. 1920-1?

A Cartier automatic, cited two ways. Antiquorum catalogs one as the Cal. 077 with 25 jewels; dealer listings give the Cal. 049, built on the ETA 2892-2 with 21 jewels. A look at the movement settles which one a given watch has.

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

Metal. Both are 33 mm automatic Santos Rondes with a white dial and a date at 3 o'clock. The 1920-1 is stainless steel throughout, case and bracelet; the 1910 has an 18k yellow gold bezel and a steel and gold bracelet.

What should I check before buying a Ref. 1920-1?

The case back for the reference and a case number; the screws on the bezel and back, all present and matching; the dial and the rim of the date window for damage; the sapphire crystal for chips; the deployant clasp, which should close firmly; and the movement, which should wind, keep time and change the date cleanly, with evidence of service.

The octagonal crown is set with a faceted sapphire. The integrated steel bracelet is fixed with screws and closes on a signed deployant clasp.

Reference Significance

The 1920-1 is the all-steel version of the 33 mm automatic Santos Ronde, beside the two-tone Ref. 1910 in steel with an 18k yellow gold bezel. Auction houses and dealers catalog it under the number 1920-1. The smaller Ref. 2966, a 29–30 mm round case with an octagonal gold bezel, is also sometimes sold as a Santos Ronde.

Historical Context

Dated examples run from the 1990s, the decade Analog/Shift gives one, through box and papers of 1999 to an example Antiquorum dates to about 2004. The first year of production is not established.

What to Look For

Case back and screws: Read the reference and case number on the back, and check that every screw on the bezel and back is present and matching.

Movement: The automatic should wind, keep time and change the date cleanly at midnight. Look at the movement itself: Antiquorum catalogs the Cal. 077, while dealer listings give the Cal. 049.

Dial and crystal: Check the dial and the rim of the date window for damage, and the sapphire crystal for chips.

Bracelet: Look for stretch and replaced links, and check that the deployant clasp closes firmly.
