Cartier W1556216 (Pre-owned - Good) — USD 53,700 on eBay

The Cartier Rotonde Flying Tourbillon W1556216 was introduced at SIHH 2012 as an entry-level tourbillon within Cartier's Fine Watchmaking collection. It aimed to make the complication more accessible with a smaller case size and a traditional aesthetic, distinguishing it from more avant-garde designs. The watch features a classic Cartier dial layout with Roman numerals and blued steel hands, maintaining a conservative elegance. This reference houses a tourbillon caliber with the Geneva Seal, previously seen in the Ballon Bleu tourbillon, adapted for the Rotonde case. The case measures 40mm in diameter, offering a more understated presence compared to larger contemporary watches. The dial is silvered guilloche with a two-level construction, where indices are elevated above the base. The Rotonde Flying Tourbillon W1556216 represents Cartier's commitment to traditional haute horlogerie while expanding its reach to a broader collector base. Its combination of a classic design, a prestigious complication, and a more modest size makes it a notable piece for collectors interested in Cartier's technical advancements and refined watchmaking.
