Depth of engagement...
Thanks Peter.
The patent drawing seems to show a screw to alter the depth of engagement of the worm. Verging on over-design at it's best 
I've always been surprised at the primitive nature of the classis regulator. There have been many patents and methods of improving it, but it's almost as though it's an after thought in the design of the movement.

Manual wind HF Chronometre anyone ?
Hello everyone.... I have been looking for vintage HF watches for a while. I set my sights on manual wind examples for my collection. As I was searching the net I came across a GP ! To make a long story shorter I am waiting for the watch to arrive. But i ...
These are nice!
Congrats!! Actually there´s a small variety of models; from what i´ve heard/seen/touched, all units seem to be crafted for Canadian Railroads: As far as i know, these go back to 1973/74. At the same time, other brands (Universal Geneve) already delivered ...
thanks.

Nice regulators...
Love the regulators on the GP and the Seiko. Don't think I've ever seen one like the GP with a worm gear before. Normal regulators really annoy me - a bad solution to a simple problem. nick
Actually that´s a GP patented solution
G'day, the fine regulation device is a patented solution by GP; it was made especially for the fast-beat movements. The US patent presented a slightly different look: And here´s one integreated in a fast-beat manual wind chronometer, caliber GP 30.7, with...
nice looking watch Bill.
dial is very 1965 Omega railmaster auto and accutron railroad approved style. unusual to see a manual wind chronometer especially a hi-beat. despite the maintainance issues i'm still drawn to vintage pieces and just picked up a nice japanese vintage. a ci...
Thanks Graham.
Hi Graham Thanks for the complement. I actually have a few of the railroad approved manual wind watches from UG , Longines and now GP. All of movements are signed either chronometer or adjusted 5 pos and temp. and all three are hacking. But the GP is the ...
