Time, Stars, And Tides, All On Your Wrist

Close-up view of the Solaria Ultra Grand Complication watch

When asked ‘what makes you tick?’ the engineers at Vacheron Constantin sure know what to answer – and fast, too. Less than a year after last year’s horological kettlebell, the 960g Berkley Grand Complication, a new invention had to be worked out. And so, they delivered. Vacheron Constantin’s Solaria Ultra Grand Complication is more than just the world’s most complicated wristwatch. It’s a fine bit of precision engineering, packed with 41 complications, 13 pending patents, and a real-time star tracker the size of a 2-Euro coin.

Yes, there’s a Westminster chime and a tourbillon, but the real novelty is a dual-sapphire sky chart that lets you track constellations using a split-second chronograph. Start the chrono at dusk, aim your arrow at the stars, and it’ll tell you when a chosen star will appear overhead that night.

Built by a single watchmaker over eight years, the 36mm-wide movement houses 1,521 parts and 204 jewels. Despite the mad complexity, the watch stays wearable at just 45mm wide and 15mm thick, smaller than your average Seamaster. This is a wonder of analog computational mechanics. Just before you think of getting it gifted for Christmas, think twice – rumors are it’ll be quite pricey.

    1. That complexity makes me want to, getting to pull out its guts and really see the ‘magic’ in a way practically nobody else ever will is enticing as a prospect. Though at the price I expect it would be, and how small and no doubt delicate once removed some of these parts will be I’d be very nervous touching it too… I might be a good enough machinst with the tools to at least make the right tools to then replace and repair anything should I screw up, but given this things tiny scale I’m not that confident in that either.

      What a crazy but genius bit of work.

        1. CAD is great, but it just isn’t the same as seeing things for real. You can’t marvel at the stupidly tiny screw on a display that makes it look more like M12 etc.

  1. It used to be that if someone was long-winded you’d say that if you asked what time it was, they’d tell you how the watch is made. But in this case, I’d really would have liked the article to give some clues as to how the watch is made.

    Oh and if you could have an article or two about Swiss 9+ DOF CNC machines, that would be a bonus.

  2. “Just before you think of getting it gifted for Christmas, think twice – rumors are it’ll be quite pricey.”

    Meanwhile, in China, some bloke is duplicating all this complexity on a smart watch and it’ll be priced under $100…

    (I’d buy it :) )
