Last weekend, I decided to do a badly needed COA on a 2414 movement. The trouble is, there is no service info available anywhere that I can find. The articles submitted by Marc_wl were very helpful, but I decided to fully disassemble the movements. So, for safety's sake, I documented the disassembly using the camera.

The next challenge was (of course) the assembly, what to oil, which oil to use, and how much. Again, there are no guidelines.

What I did was to find data sheets on other movements. I used info available from ETA and Seiko, and took what I learned in the Time Zone Watch School course 1 and 2, and made an educated guess as to what would work for the Vostok.

After all that, I printed up my notes, and did a COA on another 2414 movement. All in all, using the different junk that seems to accumulate, I was able to to take 3 broken or barely running movements and build 2 that run well.

It occurred to me that this is a resource that I can share, so here goes. What I ask is that those of you who have watchmaking experience, please critique my choices of assembly, cleaning, and lubrication. If you have any suggestions for different choices that I could have made, please let me know about it. Also, those of you in the know about watch innards, I tried to name each part. If you can think of a better name for a part that is more accurate, descriptive, or conventional, please let me know.

Also please note, the oils that I used were chosen because they were on hand from my TZWS toolkit, for use in Swiss watches. Your choice of oils may be different depending on what is available in your area.

For those of you without watchmaking experience, please note that what follows is not a tutorial. These are just my notes, and some visual reminders of what goes where. I do not discuss technique in this article. I would encourage fans of Russian watches to get some formal instruction before attempting this.

Cleaning and Oiling notes
Dave Murphy

Cleaned in ultrasonic cleaner, in 3 beakers.
Cleaning: 2 cycles in L&R Extra Fine Watch Cleaning Solution
First Rinse: 1 cycle in L&R Ultrasonic Watch Rinsing Solution
Final Rinse: 1 cycle in L&R Ultrasonic Watch Rinsing Solution

1 load: Entire keyless, setting, and calendar works EXCEPT day ring
1 Load: Motion works
1 load; all plates and bridges
1 load: Balance assembly, alone

After final rinse:
Balance assembly, balance pierced and cap jewels, shock assemblies rinsed in “One Dip” hairspring cleaner.

Oiling strategy:

Moebius 9010 on low-load jeweled pivots
Moebius 9020 on medium-load jeweled pivots
Moebius D-5 on high-load jeweled pivots
Moebius 9415 on pallet stones
Moebius 8141 in the mainspring barrel
PML Stem Grease for metal-to-metal sliding contact

Oiling amounts:
Using the black oiler,
Light = dipped to a depth 1/3 of the oiler’s width.
Medium= dipped to a depth 2/3 of the oiler’s width.
Heavy= dipped to a depth equal to the oiler’s width.

Unless noted, use light to medium oiling on the black oiler.

Hi I'm a new member and just happened to see you worked on a 2414. I just picked up one of these at a Goodwill store. Wouldn't wind up. Found that the end of the main spring reverse catch had separated. The reverse catch was originally spot welded to the main spring and this spot weld came loose. My fix was to anneal the end of the main spring and bend it back 180 degrees with a little bit of the tip bent outward to catch on the barrel, I then did a re-harden rewound the spring into the barrel and viola it's like new. Not a bad looking watch. palletstone
