Here's a quick walkthrough of an Omega cal 562 I've just finished. Prior to the photos, I've stripped the movement down and cleaned it, experimentally, in Zippo fluid in an ultrasonic bath, which seems to be extremely effective and quick. I don't have a watch cleaning machine. Comments and criticism most welcome.

 

First, I lubricate the barrel wall with braking grease 8213, and I add a dab of 8200 on the spring itself (not sure if I need to or not)

Fit the barrel bridge and centre wheel. Lubricated with HP1300

Adding the train wheels - these are fiddly (i think because the jewels are all olives)

Fit the train bridge. Lubricated with 9020

Fit the centre-seconds spring. I lubricated the seconds arbor with a tiny dab of 9020. I left the spring dry (vaguely remember reading that somewhere)

Separate the ratchet from the manual winding wheel to lubricate it (HP1300)

...and reassemble

Winding gear all back in place. Rodico will clean this up...

Pallet fork in place. Strictly no lube! Tiny dots of 9415 on the pallet jewel faces, and worked the escapement round until there was reasonable coverage.

Fitting the keyless work. 1300 on the wheel arbors, 9501 grease on the yoke and castle pinion

Disassemble the lower incabloc setting. Lubricated with 9100.

Train all together

And running quite nicely

Time to fit the motion work and the date-setting stuff. Completely forgot to take any photos!

Now the fun begins. Assembling and disassembling the reversing gear isn't trivial. I made a tool that sits in my staking tool to screw it all back together.

Here are the components of the reversing gear ready for reassembly

I sit the winding pinion on my homemade tool:

Then add the superior winding wheel (tiny dot of 9020 in the hole)
 
post-148-0-45735000-1425314935_thumb.jpg
 
Fit the superior satellite pinion to the winding wheel core. A dot of 9020 keeps it in place...

..when you sit it in the winding wheel
 
post-148-0-52719000-1425314937_thumb.jpg
 
Then add the inferior satellite pinion (their name for it, not mine)
 
post-148-0-89581800-1425314938_thumb.jpg
 
And place the inferior winding wheel over the top

Then screw the inferior nut onto the winding pinion using another home-made tool:

...and we're done. post-148-0-31962800-1425314956_thumb.jpg

 

Putting it all together on the automatic bridge

Lubricated with 9020

And fit the whole lot to the watch. The instructions tell me to dip the rotor gib in a piece of elder pith moistened with oil (9020 again)

Finally, fit in to the case. This takes several attempts since every time I attached the case clamps, a new hair or dust spec would magically appear behind the glass.

Job done. Hope that was informative.

What a cracking walkthrough and great outcome, and I'm very impressed that you took the time to make the tool for the reversing gear. I did one a few weeks back, they are superb movements. Very well done sir! :)

Lovely walkthrough and I'm also loving the home-made ingenuity! My favourite home-made tool is nothing more than a 6" nail, drilled out at the pointy end & with a thin steel nail soldered in....it's awesome for popping out dial pins, prodding & general jiggery-pokery!

Btw, I used to use butane fluid a lot until I discovered Horoloex manual watch cleaning essence (some sellers have it on eBay)...it's a fantastic solvent degreasing cleaner for all of us without watch cleaning machines. Just dunk in the parts (including balance wheels with hairsprings attached) for anything from minutes to hours & when you take them out it simply evapourates in minutes leaving them dry as a bone. Brass parts I often soak in dilute Horolene first which gives a wonderful shine.

@Profundus, you mean you don't have a proper set of  Bergeon Prodding Tools in six sizes? Pfff, amateur...

 

My normal cleaning process is 15 mins in Elma ChronoClean 1:20 at 40 degrees in an ultrasonic bath, followed by 2 rinses in Elma Suprol Pro. Apart from the Suprol stuff giving me a cracking headache, the whole process is such a palaver I wanted to see how a simple dunk in Naptha (with ultrasonic) would compare (the answer is 'favourably' -  things are less shiny, but functionally clean).

    • If the watch is new, just return it to the seller for a refund or replacement.
    • Keevo, Welcome to the group ! I'm thinking that you have some damage to the hour, and/ or minute wheel. Possibly just a bent, otherwise damaged, or missing tooth.   Your photo didn't post that I can see. I think you'll have to open it to start really finding the issue. Best, Randy
    • An industrial break cleaner , like Holts does a good job of rinsing off paraffin 
    • In cap jewels on several watches I have serviced over the years. I've recently serviced a couple of Longines movements where the cap jewels were colourless. They are a real pain. Without colour they disappear when immersed in any liquid for cleaning 😲 Not necessarily. Cousins do a 10ml bottle for £26 which will last me for years. That's just half the price of a simple Bergeon silicone cushion, so not too expensive 🤣
    • I wanted to post an update as I have two movements running really well now, 230-250 amplitude , 0.5 and under beat error, and +/-8 seconds or so. I removed the hairspring assembly in order to start over and noticed that the terminal curve between the stud and regulator arm was distorted. The stud was lower than it should be. I massaged the curve to look pretty good and reinstalled it. I followed Alex's video advice, best I could with 10x magnification, and with the regulator arm set in the middle of the curve I adjusted the stud so the spring was centered. I then made sure I could move the regulator arm the entire terminal curve without upsetting the coils. I then put it back on the Timegrapher and began closing down the regulator pins until I saw a change in amplitude which means to me that the pins were now pinching the spring. I opened them slightly and it looks good except I have a 0 on dial down, +3 on dial up but -16 on crown down.  I'm a bit stuck on how to adjust out the positional error. I also noticed a drop in amplitude, 180-200 on crown down. In the other video link I posted at about minute 26 if I remember he adjusts out positional error by manipulating  the regulator pin gap. With crown down the hairspring falls away from the pin and the rate slows so he closes the pins a bit to keep them tighter in crown down position. That means the spring is tighter on dial up as well but then he moved the regulator arm to slow the movement.  There must be some Seiko experts here that have some methods for dialing out positional errors.
