Got a non-running ladies Seconda (oval, 17 jewels, "129393" on case back, "SU" on bridge & "1301" on barrel wheel) which on opening showed the click area to be badly rusted. It looks (see photo, taken after cleaning) to my inexperienced eye like one end of the spring has broken off (I'm assuming one end sits in the hole in the barrel plate & the other end (anti-parallel) - the missing bit - comes up through the slot in the click itself.  What're the prospects of finding a replacement? Oh, and I managed to sheer the head off the screw securing the barrel wheel so I need a replacement for that too! I know the watch is of little value but I'd like to get it working if I can.

If you post a pic of the whole movement (both sides if possible) then it might be possible to identify it which would make tracking down replacements or a donor a bit easier.

Odds on that it is Russian though.

Thanks, rj. Been looking at these & similar. One description says they can be bent to shape which I'm assuming I won't be lucky enough to avoid having to do. So does one anneal before (& after) ? My spring is only ~1.5mm across & the wire seems less than a hair's breadth thick so that'd be a very interesting task for a novice!

Apologies for imposing further but any views on the practicality of finding a replacement barrel (Ratchet?) wheel screw?

Thanks for your interest, Marc. 17176081749178638589136029790682.thumb.jpg.b479392047c481aab6518781dac01eae.jpgHere's what it looks like at present: clearly from the "evil empire"!

It's a Chaika, sorted my sister's a few years ago.

Yes, Chajka (Чайка)1301 . The click spring can be made of spring steel wire. No annealing needed for such steel. Such wire are the springs for violin and guitar, but this spring is thinner than the thinnest violin string. Spring from another movement can be reshaped, as suggested.

Such movement can be obtained for less than 50 p in Russia, but I am not sure if this is an option now.

The broken piece of the barrel screw can be unscrewed with hard sharp pointed tool. The screw is not tightened now, as the head is not there, so it should unscrew without resistence.

Thanks for the info, Nev. I'd got the barrel screw out straight away: it was indeed quite loose.

Hi Rich,

I am not sure what You ask for, to translate something in Russian? No problem, but I don't understand the meaning of 'get stuffed'.

OK, asked Google and I think I gоt it. May be ''Заткнись!''

I'm just being silly Nev.  I can teach you some slang English.  " get stuffed " means  " go away " in a non polite way 😅 . But I did google it for a Russian translation.  I used to have a Russian neighbour he used to teach me a few phrases.

You need to find someone who plays guitar, the strings make excellent spring material

9 size guitar string is 0.22mm, 10 is 0.25 and 11 is 0.28 as I remember.  The violin thinnest string is 0.2.  I often use these for repivoting... The Chaika click spring should be 0.12 -0.15

There are all kinds of guitar gauges

For example these are:

image.thumb.png.402a443882fc1a30f41512bb935ae22a.png

8 = 0.008 inches = 0.20 mm

11 - 0.011 inches = 0.28 mm

And so on....

Note:

Gauge/1000 = inches

Inches x 25.4 = mm

 

Maybe too thin in the case of the click spring, but worth keeping in mind for future spring makes..... my son goes through set of strings a month, so lots of spring material in my spares draw.

    • Alex mentions the coils below the stud should remain the same as you move the regulator block along the terminal curve.  Mine do that. What he doesn’t discuss and is used in the other video is how the regulator block is used to adjust rate and positional error.  He also doesn’t mention how opening and closing the pins could and in my case does, alter amplitude  In Alex’s video once he sets the stud he never adjusts the regulator pins yet every new movement I get have the pins signing closed. 
    • The video I linked above does mention the spacing of the hairspring coils, and the importance of the regulator being able to move through its full range without distorting the hairspring - the terminal curve of the hairspring must be concentric with the regulator pins throughout the regulator’s range.  If you meticulously follow every step in this video, the regulator system should behave as intended, regardless of the brand of the movement.  Best Regards, Mark
    • Hi friends! My mother got a bunch of old watches from a horologist who was retiring, and he subsequently passed away. It's been in her studio for years, and she showed it to me today and I just fell in love with it. Sadly, I don't know a darn thing about it yet. It's quite old, or at least seems to be. It has two winding arbors, but the key is missing. The crystal appears to be some kind of yellowed plastic, which is odd- I think it was replaced at some point to possibly protect it or something. If I had to guess, it's from the mid-19th century, given that it has no keyless works and that it says "Anchor Escapement" in French. It looks to be about 18 ligne, and the case fob is positioned in the upper right corner. The face is missing the dial, the hands, and a couple of the wheels that drive the hands- I think. But the movement itself seems to be in excellent shape. The serial number on the movement matches the number on the case- it's stamped on the movement and on the case in two places. I haven't started any disassembly yet, but I'm wondering if anyone can give me some idea of what kind of movement it is, and where I might look to see what parts are missing from the face. i may even have a dial that would fit it. It's in good enough shape that I think I could get it running, assuming I could find the missing parts. Any insights are vastly appreciated and thank you! Addendum: The inside of the case has some *very* tiny scratched numbers and letters in it, but I am having an extremely hard time seeing what they are. Like "N 99" and "No192X", They were clearly done with some kind of sharp stylus and maybe they mean when it was serviced or by who? Addendum the second: At least one of the scratches seems to say "N1921X" or maybe "W1921X". Serviced in 1921? And the inside lid of the case has the letters R H with a star between them, and a very tiny mark that says "ARGENT" in a u-shape.
    • I’ve watched every video I can find on YouTube. Some of the info is contradictory and none mention  the effect on amplitude or spring coil spacing which I observed. I was hoping someone here is a Seiko expert and knows these inside out.   
    • This video explains how to set up and adjust the etachron regulator :   I hope that helps, Mark
