Not sure there is a simple answer
Andrew, I think the "fast and light" vs. "slow and heavy" balance wheel question doesn't have a simple answer.
A large wheel with a large moment of inertia should resist the effects of small disturbances better, but when disturbed, will take longer to recover its normal rate.
A light wheel with a small moment of inertia will be more affected by disruptions, but should recover more quickly.
There is the additional question of a severe shock to the movement, which I would imagine would be more likely to break pivots of a large balance.
I read once that fast beat watches were easier to adjust to run stably in multiple positions, versus a slow beater. A watchmaker should weigh in on this.

A Zenith mega-photo-thread to christen the new forum ...
The Zenith Forum is exciting news and perfectly timed to coincide with a re-energized Zenith. But of course there is plenty of Zenith history to draw from as well. I thought it would be fitting to start off with as many Zenith pieces as we can squeeze int...
Do pocket watches count? . . .
. . . if so, then here's my contribution - a '27 (or thereabouts) Zenith that has been handed down two generations . . . . . . and holds pride of place amongst my possessions. Cordially, Art...
A very interesting piece...
An interesting piece indeed, looking at the hour markers makes this piece quite unique among all Zenith watches. Thanks for sharing this rare sight!
As written above, a "Turkish dial" ...
... which was common on watches exported to the Ottoman empire, but also - if I recall correctly - in Armenia and a large part of the Middle East. Regards, Marcus
Alrighty!
The grandaddy Primero, ref A 386 Two Pimeros and a Cairelli enough with the old stuff, how about a new Charles Vermot LE? and my last watch purchase of 2011, a pre-Primero diver, ref. A 3736 Zenith - what a great manufacture! This message has been edited ...
Exhibit "A" . . .
. . . in the case for Zenith chronographs, El Primero or otherwise. The blue-dialed cushion case example from the first generation in particular . . . damn handsome watch, and worthy of a reprise, methinks. Cordially, Art
A good example of the understated . . .
. . . aesthetic tonality that Zenith reflected in times past, and currently. Thanks for sharing, Maarten . . . cordially, Art
A few Zeniths
Hi Andrew Ok will play... A pair of Zenith Delucas El Primero cal 400 powered. one black and one in white ( I let the white one go a while ago). A Zenith Captain chronometer powered by a caliber 135. A few first generation El Primeros... 18k yellow gold ....
The first phrase that's associated with Zenith . . .
. . . is "El Primero", but the second has got to be "caliber 135"! It's almost not fair that you've had three in your possession at one time or another ;-) . . .
I'll play ...
Only 2 Zenith timepieces in my collection at the moment ... (a) Zenith Chronomaster T Moonphase (b) Zenith Rainbow Flyback...
A pair of El Primeros is . . .
. . . a fine collection, Peter. That Rainbow Flyback would be a contender in any list of recent vintage sports chronos, alongside the likes of the Speedmaster, Flieger, and Fifty Fathoms . . . cordially, Art
Zenith clearly had a workable formula . . .
. . . when these El Primeros were minted: sensibly sized and well proportioned watches with a pronounced aesthetic, and showcasing a high performance movement. This genre of El Primero evinces a high level of intrinsic value; anecdotally, at least, it see...
A BOMB...

A poignant reminder . . .
. . . that formal wear is also a strength of Zenith's. Thanks for sharing your pair of rose gold black-dialed beauties . . . cordially, Art
Couldn't agree more ...
and it's something that tends to be overlooked (or overshadowed by the magnificent El Primero). Thanks for pointing that out.
Letz rock with G-force!

The cushion cases
from the early Primeros might just be the most misunderstood and under-appreciated cases in watch-dom. They are supremely comfortable, catch the light beautifully, and have a wrist presence all their own. As attractive as the round cased Primero is, the c...
Welcome, Rob . . .
. . . and thanks for sharing your collection of recent El Primeros. The rose gold black-dialed triple calendar is something special ;-) . . . cordially, Art
There have been some gems in the Zenith catalogue ...

I love your watch. Do you have a picture of the back? Is the calendar instantaneous? i.e. midnight?
spectacular
...collection of Pilot Specials. Are there any versions that you don't have? I'm particularly impressed that a few of them still have the thick crystal. Are they original, or have you managed to source replacements somewhere? Super rare!
thanks
some not in my collection yet, i will post if i have chance to grab those. for mine, they all are as the date when i bought, no source, sorry not able to help
Bill Sohne and myself were just discussing . . .
. . . your collection of vintage Zenith aviators, Bernard - very cool!
Great Pilot's watches
a brilliant family photo of Zenith pilots. I Loooooove this watch and have a few in my collection as well.
Zenith Rainbox Flyback (color)

I'm embarrassed to say that ...

Kingmatic is not a Zenith model/movement
It belongs to Movado. I believe Kingmatic is simply the poster's name (I think I remember a very beautiful Movado Datron he showed once, right K?) Zenith and Movado were once part of the same holding company, and there was a lot of sharing of movements bo...
Wow! What beautiful pieces!
It really is an eye opener as I never really gave Zenith as second thought. I've changed my min, though. This brand warrants some looking into. Aloha, Bob
My humble contribution
Hi Andrew, glad to find a Zenith forum now! As you know already - I mainly collect vintage Omegas... But I think when collecting watches one has to own at least THE Zenith icon: Cal. 135 chronometer So I have added 2 examples to my humble collection: As y...
No wonder the Cal. 135 is famous ...
It looks fantastic. Particularly that beautiful balance wheel and stylized swans neck regulator. Unfortunately I can't quite work out from the picture how it is regulated. A very nice pair. Andrew
I will try to explain...
It is not so easy to explain as I do not know all the correct expressions in English (I am not a native speaker!). I have marked and numbered important parts: As the slotted disk (A) is turned, the arched spring (D) presses a pin under the regulator arm (...
Very much appreciated, Erich
I understand completely, and I'm sure Steve won't mind with appropriate attribution as you have done. I should go hunting for the information but I'm feeling lazy! Can you tell me the speed and power reserve of the movement? The explanation is much apprec...
The speed should...
Andrew, to be honest I do not know the power reserve as I would have to check it... (it has a huge barrel, not only a huge balance) For the speed I guess it is 18.000 (if I recall correctly) - it is a slow beater at the lower end compared to the El Primer...
Large balance
Thanks Eric, This obviously deserves a thread by itself, but I assume then that this movement would function chronometrically much better in a static environment (ie, off the wrist) and that it would be prone to disruption on a moving wrist with jolts. Ha...

Beautiful 135's, Erich, and rare to find in such good condition. Regarding the jeweling, do you know how the 19 rubies are distributed? If I count, I get the standard 17 to the center wheel, plus an upper cap jewel for the escape wheel (18) and an upper h...

Great photos

Very interesting to hear this history. Beautiful movement shots and watches too. Andrew
Touchy question: would one variation . . .

My Zenith Special!
This watch is circa 1930. I was told it was made for the German Luftwaffe. I have close friends whose family perished in the Holocaust but you have to admit, the German military watches were very cool!! This watch is around 40mm in diameter, with a see-th...
Great Zenith Special
I don't think they were made specifically for the German military, although they certainly may have used this style of watch. Many different manufacturers made a watch like this, from small companies like Recta and Helvetia to well known names like Breitl...
The height of optimism . . .
. . . is illustrated in the 1946 catalog with the listing of a bombardier's watch in German . . . hard to believe there were any takers at the time ;-).
These military designs that . . .
. . . are contemporary with the Second World War can understandably lend to conflicted emotions. One wonders if the Swiss watch industry ever marketed the same model to both sides of the conflict . . .
Can you doubt it
...given the Swiss track record in other aspects of commerce during WWII? Prolly best to veer away from this topic.....
