2 variations of an interesting vintage Longines: The Nonius Chronograph.
2 iterations, well, I would say that for me, there is only one Nonius, the version housing the famous cal 30CH: While the later is not bad looking at all, but it houses a more pedestrian Valjoux movement. Why Nonius? Because you have a 9 seconds scale, yo...
Isn’t that Nonius for 10th of seconds like on a micrometer scale?
I.e. when one number hits the scale line perfectly, its for the 10th of a second? Best, Jens
Very quirky looking watches but quite nice.
The nine minutes scale looks a bit strange and, I have to admit, baffles me. I can’t figure out what it’s for. Regards Kev.
Its also called a Vernier Scale
It is used to improve the precision of reading for 10th of seconds (although none of the movements used is a hi-beat-movement). Best described in Wikipedia. Best, Jens
I own a Nonius!
It's quite an incredible watch! The movement is about as good a it gets for any price... and the dial is so LONGINES, so 60's... When I bought it, (10 years ago?) I wasn't really sure what I was doing... I just loved it and wasn't sure if anyone on earth ...
I know Nicolas, I have to
I am so bad about pics. It is certainly an economical way to own this crazy-beautiful, legendary movement
Here are pics of perhaps the most intriguing 30CH ever . . .
. . . owned by Steve G . . . . . . and posted here with previously granted permission. For those unaware, it's a unique Longines prepared especially for Steve. Art ...
Steve's 30CH is a . . .
. . . piece unique produced ~ twenty years ago, decades after the movement was out of production, by Longines as a gift to one of their employees. (This info is from Steve's website). It's literally the last 30CH made. Art ...
Six or seven years ago, there were two available from the same seller a half-hour drive . . .
. . . from my place, one in slightly better condition than the other, both in the high $3K range. I thought long and hard about them, but passed, much to my regret. That was my last chance at owning a 30CH. They've gone thru the roof since. Art
Totally agreed, Nicolas . . .
. . . but the hazards and pitfalls of vintage collecting have increased markedly in the last few years. Five years ago I could acquire any vintage Omega and be fully confident it could be restored to correct condition. Not today, unfortunately. There will...
The short version of the long story is that my most recent foray into vintage Omega . . .
. . . was almost torpedoed by parts availability, or more precisely, unavailability. The efforts I'm being forced to make to bring a ref 2518 to correct condition are unsustainable. And parts availability for other manufacturers, particularly highly finis...
