Blancpain Villeret
Ref. 6651-3642-55B
An 18ct red gold case measuring 40mm across and just 8.7mm thick gives this Villeret a notably slender profile on the wrist. The opaline dial carries applied polished rose gold Roman numerals and leaf-shaped skeletonised hands of the same metal, with a date window at three o'clock and a power reserve indicator. A transparent sapphire caseback reveals the calibre 1151 beneath, a self-winding movement running at 21,600vph with a silicon balance spring and a power reserve of approximately 100 hours. A brown alligator leather strap completes the watch.

Learn more about Blancpain
Jehan-Jacques Blancpain registered as a watchmaker in Villeret in 1735, which makes Blancpain the oldest name in the industry by registration date. The dial still carries JB 1735.
The claim comes with an asterisk the house is candid about: production stopped during the quartz crisis. The name was dormant until Jean-Claude Biver and Jacques Piguet bought it in 1983 and relaunched it on a defiantly contrarian promise — there has never been a quartz Blancpain, and there never will be. In a market then convinced mechanical watchmaking was finished, this proved commercially astute as well as romantic.
The technical high-water mark of the modern era came in 1991 with the 1735 Grande Complication, which combined a tourbillon, perpetual calendar, moon phase, minute repeater, and split-seconds chronograph in one wristwatch.
Blancpain's other lasting contribution is the Fifty Fathoms of 1953, developed with French combat divers and predating the Submariner. It established the vocabulary of the dive watch — rotating bezel, high legibility, real water resistance — and remains the collection most buyers know.
The Swatch Group acquired the brand in 1992. The Villeret line continues the classical side of the house: round cases, double stepped bezels, and complications presented without ornament.

Frequently asked questions, and things you should know about this watch
Can I swim with it?
No. At 30m it will survive rain and handwashing, but not submersion of any kind.
Water resistance explainedWill the glass scratch?
Unlikely. Sapphire is second only to diamond in hardness and shrugs off everyday marking.
Sapphire, mineral and acrylic comparedDoes it need a battery?
No. It is automatic — the motion of your wrist winds it, and there is no cell to replace.
Quartz, automatic and solar comparedHow long does it run for when it's not worn?
About 100 hours fully wound — enough to sit off the wrist over a weekend and still be running.
