Slated for Wednesday, November 30, in Hong Kong, Christie’s Blockbuster Sale of Important Watches features more than 550 rare timepieces spanning 400 years in time. Approximately $11 million worth of wristwatches, pocket watches, ring and even belt-buckle watches will be on the auction block. You don’t, of course, have to spend millions. Many pieces are affordable, expected to sell for less than $10,000, while others will garner much more. Among the highlights: Patek Philippe’s Ref. 2524 (estimated to sell for between $250,000 – $350,000) is the only one to be fitted with a two-tone silver dial with alternating baton and Roman numerals. Just 12 of this reference are known to have been made; the amazing haute joaillerie Vacheron Constantin Pagoda Kalla (est. $150,000-$250,000) is set with 312 diamonds weighing approximately 65 carats. For those who prefer antiques, there are many delights, including a stunning rare and previously unrecorded enamel and diamond-set ring watch, circa 1810. Expected to garner between $87,500 and $112,500, the ring watch is one of the most special pieces, s it features a quarter repeating mechanism and two cupid automatons – in an amazingly small space.
