I felt silly. Now I know I am.

Working on an Enicar with AR77 movement. Get a spare. Sold as needs repair Back tight but 'ticks'. Photograph from seller showed 'chisel' marks on the back. Me thinks it has not been opened so I may get some good spares. Take a chance.

Can I repeat the title 'I felt silly. Now I know I am'.

Opened with care. Aaagh!

Always a risk not seeing what is inside the watch.

"Always a risk not seeing what is inside the watch."

Have to agree. However, it has taken me 3 hours to disassemble. 

Observations.

I was not the first.

Dial side. Dial and calendar = gunk every where. Looks like glue? It wasn't, but flakes everywhere. Scrap

WD40 on seized parts. Nearly everything.

3 seized screws broken heads. Barrel  bridge. Balance cock. Train bridge. Gentle easing on bridges and cock and they lifted past the head. Phew?

The balance spring is in superb condition. All parts appear in good condition. Amazing. All will be reusable after cleaning.

1. Broken part. Calendar quick jump lever. (Bummer, this is the part I needed). Spring for Calendar jump lever missing. (I've got one of these)

Really enjoyed this disassemble. No pings or damage on my part.

Video made of the whole thing. Not going to post it as I would have to learn how to re-edit. Been so long since I used the video software.

Hi Ross.  Methinks it’s time for Nucejoes can of coke, looks a bit grim in there.

Me thinks ,  No way this watch will ever get young. 

🤣

My mantra, which I repeat over and over "never buy a watch unless you see pics of the movement"

(But I am guilty of not doing this on some cheap watches which seem OK. And yes, I have ended up with Mubai Specials 🤣)

'That's not going to get better...'

Sorry mate. Good news is your attitude towards it is brilliant. I've over paid for a few unsalvageables, even after seeing the movement. Give it a 'permanent' home in a parts tray and you can pick away at it when you have only short time, you can find out what it needs instead of the bin, experiment with new techniques, discover you can save elements as your skills improve, etc. I have a waltham A-11 that was always a rusty 'parts' watch but with all the above it is a set of hands away from being a wearable timekeeper...keep at it...

"Once cleaned, reassemble, bag,  label the calibre and all usable parts". 

Doing, as Richard and rehajm have suggested. Even going to try Nucejoe's Coca Cola clean. 

 

Just a note. The movement is an AR167, not AR77. Keypads pressed in error.

Regards to all.

So what the seller is saying is that he returned home after a night of drinking and found he'd been bitten by tiny arachnids? They certainly weren't describing the watch. 🙄

You can soak it in black tea overnight, like I did with an Omega Sea Master, butsome of the parts may simply disintegrate afterwards. Hope it all gets sorted out!

Really pleased with this project. Looks like it will clean well. 

On the main plate. The two screw threads need to be removed. Not sure I will use the plate, but will be a good exercise.

Looking at the photograph of the mainspring I did think it was a break, but in fact is was a substance from the calendar wheel. It is now removed. Phew.

Sometimes it's good to challenge yourself just to see how far you have come. Looks like you will have a high percentage of useable parts that will come in handy some day for sure.

When I store parts like this I usually put them in a small sealable bag with a silica gel pad inside. You can get these on Amazon for a matter of pennies each and it's cheap insurance that the parts will be in good condition when you need them, see below.

For removing rust (iron oxides) I have found commercial rust remover works well eg evaporust or similar. And for verdigris (copper/brass corrosion product) I have good success with white vinegar from the food isle in the supermarket, you can also use any spare on your chips, but don't get them mixed up 🤮

I did a study at university on using coke to remove rust and used an electron microscope to see the after effects. The problem is that the acid in the coke attacks the steel indiscrimenently unlike the commercial rust products which are pH neutral and only react with the iron oxide. But I know some people have good success with coke or tea or...? So I don't mean to come off as saying they are wrong, I would just advise that anyone should just try the commercial stuff out and then compare to the coke etc and see what works best for you.

    • 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.
