Hi  

Are there some omega experts that can tell if anything looks wrong by looking at the movement image?

I'm told that the chronograph function doesn't work but the watch runs fine. 

But nothing happens when Chrono buttons are pushed in or they might not be able to be pushed in. I'd like to know if it's worth buying. 

Is it maybe just a cleaning project?

there are very troubling signs in your image. The gasket does not look nice and clean it looks like a lot of debris on the gasket and it looks like a lot of debris on the movement ring and none that would be good in the watch itself. This is where people forget when they never get their watch service the gaskets will disintegrate. Disintegrating gaskets are bad because then moisture would get in and that's then very very bad and that's not always going to be visible.

then pictures are usually helpful but the video would be better. As we need to see what happens when buttons are being pushed.

hard to tell but the case clamp on the left-hand side doesn't quite look right in other words it doesn't match the one on the other side? has anyone been the watch before you?

this watch isn't quite like a stopwatch a stopwatch has way more metal on metal contact I have a stopwatch at work that the stopwatch wasn't working and it was basically just sticky grease holding things in place. But you wouldn't want to service this watch and see understand why the chronograph isn't working.

oh? It's back to the video but if the watches never ever been cleaned if you push and the buttons to the push it all? If the watch was super super dirty maybe the buttons art even moving? This is back to when the back is off a new push the buttons what do you see happening anything happen at all? Because something you should move the return the zero won't work unless you're in the right position so it has to be stopped the start stop should work.

And yes usually Omega chronographs are worth buying expensive to prices could

But the asking price is around 2000-2200 USD. Is that fair?

One of the problems with asking prices are who's purchasing? For instance if you're purchasing this for yourself that you'll pay a higher price then if you are purchasing it with the thoughts of fixing it and then selling it. 

I was looking at eBay and a variety of silly asking prices so then you look at the completed sales prices and some of them are less than $2000 you'd have to read the description of why which I'm not going to do. Some are more than $2000.

Oh and when you're looking at eBay you actually have to read the listings because they're misleading. One of the watches that came up for a very very cheap price says pre 321 Which is why it was so cheap. Then there was another one that one of the components like the bezel was supposed to be on a 321. So you have to read to make sure it actually is a 321 movement.

I did find the interesting link below from Omega you can see some nice colorful pictures of the movement

the only thing as a reminder is because it is an Omega watch if you've never worked on a chronograph you don't want to make a mistake on this one because parts are going to be very expensive.

I don't see anything broken or missing, but it is in dire need of a service. I can't tell on this one, I usually see Speedmasters (what model is this?), but there are usually some goofy looking bits that interface between the case pushers and the chrono mechanism through the case ringl; if there has been water intrusion these can rust badly and bind up in the case ring. My gut says it's a safe bet at that price, just going on what 321 movements go for, but I'm no price expert.

I chose not to buy it. It was ref. 145.006. Its sold for around 2500 USD. I would have bought it for myself and try work with it myself or send it to a authorised watchmaker. I have good experience with servicing landeron 48/248 and valjoux 7733ish chronos so thought it could be fun but didn't feel comfortable about buying it as parts hard to get🤓. 

Appreciate the knowledge sharing!

      So fsr as assembly, I don't think you would find 5646 different from 5606, just that GS is 36000 beater. No unknown chalange is there as long as the escapement reamins undameged. Rgda

      no, I have no alternatives and don't know of any. I've bought Mobius and that's all I have. 9010, 9104, 941, D5, 8000 and Moly-Kote.

      I've just had the wood stove door seal replaced. I was hoping not to need to do that again for a few years. In the name of science I can't say I'm not tempted. I mean how dangerous can it be? Says the man who encouraged his friend the plumber to use phosphoric acid to dislodge the solidified sodium hydroxide that had blocked the bath U bend. We did take that outside first though, and yes, adding concentrated phosphoric acid to sodium hydroxide crystals and drain sludge is as bad an idea as it sounds.. so we did it several times, laughing like delinquent school boys until the explosions of brown goop stopped. The operation was a success, but sadly the patient died (or rather, melted), and we had to replace the U bend anyway.  Children, please don't try this at home.

      I don't usually fancy the yellow crystals but it seems to work with that dial... ...and you can't set fire to it unless you share video. I speak for all of us...

      For the last couple of evenings, I've been working on an Amida 15 Jewel based on the Amida 500 movement from sometime around 1950. This is a slightly odd mechanism, as it has the initial appearance of a jewelled lever arrangement, but is in fact a pin lever. The movement is well made, and pretty easy to work on. After a little swithering, I did change the crystal. It looked original, and I would probably have left it alone, but it had yellowed somewhat, but the thing that sealed its fate was the crazing that became evident if the light struck it from just the right direction.  As you can see, it made a marked difference to its appearance, although some might argue that the yellowing gave it a warmer look. I'm in two minds also regarding the hands. I suspect they might polish nicely, but the nagging voice in my head is saying, they might also end up looking uneven. It does run reasonably well all things considered. It doesn't quite qualify for the 404 club, as it came in at a rather too hefty price tag of £4.99 GBP. but since I've made a few other exceptions to the rules recently, it may just get an honorary membership. There are a couple of other issue I need to address. The first is the fixed pins and rather small lug width, which measures at a rather odd 15.3mm. I'll either need to source a strap, or perhaps use this an opportunity to make a custom sized strap for it.  The second issue is.. do I dare set fire to the old crystal, just to see if it is made of nitrocellulose? If you hear a loud bang and detect the smell of singed eyebrows, then you will know the answer.
