    Whilst not quite a jump-hour watch, the Audemars Piguet Star Wheel’s sapphire disks jump into position, right before sliding over the minutes track.

    I bought the watch many years ago, and a similar one was offered yesterday at the Phillips Auction. I was surprised at the price, considering it was more than double the initial estimate. The example auctioned has a different design on the dial, I always preferred the scroll motif over the guilloché dial.

    Here is a beautiful English jump seconds pocket watch.
    Puzzled by it having two seconds hands, I thought it was simply a stop watch or 'Doctors' watch until I got it home. My friend liked the Fleur de Lys hands, so I bought it. You will notice two mainsprings, one for the going train and the other for the jump mechanism. In lovely condition.

    *Oversharing Warning*

    Oh man, I used to almost exclusively collect jump hours. I also taught myself to fix them since some of them are so finicky (Lord Elgin and Benrus Dial O Rama especially).

    Here are are few choice ones I have/had in my collection:

    Tenor Dorly Sky Raker - Only a handful known to exist. released the year they went out of business:

    Super uncommon ESA electronic based jump hour and jump minute.

    Lip Retrograde/flyback

    Screen Shot 2020-11-10 at 10.01.56 AM.png

    Wittnauer Futura 1000, same flyback mechanism as the LIP. Different movement.

    Bulova Art Deco "White Knight". Same FHF as the OP.

    A couple of contenders, although neither are true jump hours.

    upload_2020-11-14_9-17-38.jpeg

    Zodiac Astrographic. I’d call this more of a wandering hour (and minutes and seconds).

    upload_2020-11-14_9-23-40.jpeg

    Gruen Airflight I. This one is a jump AM/PM. At 1 o’clock, there is a barely audible click and the ring inside moves.

    upload_2020-11-14_9-26-5.jpeg

    It’s really a 24 hour movement done in a different way. The movement is actually the same as the Day Night version from @X350 XJR above.

    Recently bagged a Gérald Genta Jump hour retrograde. Absolutely love it. Comes with a swish MOP center dial to boot.
