Visual Description
The Ref. 2425 is a Santos Galbée chronograph. Antiquorum, Sotheby's and Dorotheum catalog the case in stainless steel and 18k yellow gold; Fellows and Dorotheum give it as about 29 mm wide. The dial is silvered, cream or off-white, with Roman numerals, a 30-minute and a 12-hour register near 4 and 8 o'clock and a date window at 12 o'clock, under a sapphire crystal, with blued steel épée hands in Antiquorum's description. The integrated bracelet has steel links with yellow gold screws, or steel and gold links, and a deployant clasp.
Reference Significance
The 2425 is the chronograph among the Galbées on Archiva, and the only one with its date at 12 o'clock. The three-hand steel and gold quartz Ref. 187901 and Ref. 1566 have their date at 6.
Fellows and Dorotheum catalog the movement as the Cartier quartz chronograph Cal. 222, and Antiquorum as the Cal. 222P with 25 jewels. Fellows calls the watch the Santos Chronoflex and Antiquorum the Chronoreflex.
Catalogs measure the case differently: Antiquorum gives 30 × 36 mm and Sotheby's 28.5 × 41 mm. Fellows calls it mid-size.
Historical Context
Antiquorum dates an example to the 1990s, Sotheby's one to about 1998 and Dorotheum one to about 2000. The first and last years of production are not documented. Antiquorum has cataloged the same watch twice under Ref. W20042C4, with case No. 100515BB 2425.
What to Look For
Case back: It should read 2425, with a serial in the BB series.
Chronograph: The chronograph should start, stop and reset, and the registers should return to zero. The date should change cleanly at 12 o'clock.
Metal: The gold parts should match in color and show no wear through.
Bracelet: Look for stretch and replaced links, and check that the deployant clasp closes firmly.
