Does anyone here know why GP Gyromatic has 39 jewels? What makes it need 39 jewels to run?
I'm not sure if this is your answer but the Seiko Weekdater also had 39 jewels, a number of which were used just for the date and day wheels to ensure there was no "stutter". I would guess that some of those jewels are not in the movement itself (if that makes sense?).
Movado/Zenith Big Blue with its 3019 in there... And a wrongly setup date
A Seiko collector recently posted this 57600bph prototype King Seiko on his Instagram, along with some interesting info about Seiko’s experiments with high and very high beat movements (up to 25Hz - or 180 000 bph!) back in the 60s.
Short version is that going higher than 36000 presented them with technical problems that couldn't be solved back then, at least for a production watch.
Just got the UN ref. P261 ( on the right ) today ....On the P261, I really like the way UN embedded the date magnifier under the crystal surface- no cyclops to mar , IMO-the watch ....def have to swap out the strap...
A sad lack of Omegas here. May I offer the 36,000 bph 53.7 split-second/rattrapante Olympic?
I still refer to the thread by MSNWatch, which says it all:
I agree with his view that this was “One Of The Most Beautiful Movements Omega Ever Made”. Originally a Lemania movement of course (so was the 321!), this started life in 1932 (for the Olympics) and was produced in various forms over many years. This one the rather special 206.
The images from MSNWatch’s thread:
Here's one that's seldom seen:
Juvenia calibre 959
Used to have a mesh-type bracelet; unfortunately, the integrated spring bars fell out when taking the bracelet out and its been on a strap ever since.
Longines Ultra-Chron from 1967 cal 431.
Sold it very recently, because it's not really my taste of a watch and it was sadly sitting in the box.
But it used to run COSC time.
Movado Zenith 408:
New member here with my first post while I bide my time waiting for July 20 to see if Omega comes out with any new interesting Speedies. This is the first mechanical I purchased for myself.
