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.
the mechanism seems like the same. but i'm more glued on the hand engraved design on the dial. very nice.
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. https://www.phillips.com/detail/audemars-piguet/CH080220/150
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 Wittnauer Futura 1000, same flyback mechanism as the LIP. Different movement. Bulova Art Deco "White Knight". Same FHF as the OP. Lord Elgin Chevron. I've made a few custom nickel plated versions like this Original Gold Classis star dial Benrus Dial O Rama. Yema An old group shot, many of these were sold, and many added after:
A couple of contenders, although neither are true jump hours. Zodiac Astrographic. I’d call this more of a wandering hour (and minutes and seconds). 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. 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. gatorcpa
Recently bagged a Gérald Genta Jump hour retrograde. Absolutely love it. Comes with a swish MOP center dial to boot.
