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!

      Looks that way, if it had any amount of significant jewel count it would say so on the dial.    Looks that way, if it had any amount of significant jewel count it would say so on the dial.  Same answer as Mike regarding the dial, its often just a slapped on name of a retailer but i thought you were way above this understanding Pete ?

      Light naptha is what you need to be looking for. The carbon to hydrogen ratio is high with heavy naptha, it doesn't evaporate as well as light naptha and is prone to leaving more residue. Try tom's suggestion of the mirror test.

      Its a big item Michael and a lot that could go wrong with the process of getting it to its new location. I once helped install one of these units into a conservatory that i had built. It was big and bloody heavy and took six of us to get it in safely. If you have sliding doors and you need to remove the whole frame then that may or may not go well. But i would advise getting a professional in if you have little knowledge on the installation of them. The glazing of the doors could well be 6mm laminated glass which again will be heavy very heavy if the glazing units are big. The glass would also need to be set up and packed correctly to open the doors properly more so if they are unframed and the sliders are upvc. Seems a shame but if no one is biting and that may be due to having no warranty i guess the only takers might be someone that installs them for a living and knows how to repair. If its fibreglass just be careful, i sometimes have to cut fibreglass baths out and they are nasty to work with . Thick gloves are definitely recommended,  not fun picking out fibreglass spells two days later that have started to go septic. Good luck with it all matey.

      I don’t know anything about this product, however assuming you have it if you put a drop on a mirror or piece of glass lying flat on a table and leave it to evaporate if it leaves any sort of residue it is not really suitable for watch part cleaning.   Tom

      Well I put the spa on Gumtree (selling service) to try and sell it as it only needs a recirc pump to get it going. However, it weighs circa 250kg, so there's 4 fairly strong guys, and I would have to remove the sliding door in the room completely to be able to get it out, as well as clearing out a multitude of potted plants and the Alfresco outdoor setting to be able to get it out. Then move nearly everything in the back of the garage to be able to push it through to the front of the house. I would also need to hire furniture skates to be able to shift it around as carrying it is out of the question. Then someone would need a trailer to get it to their place as you won't get it on the back of a ute. So, the only answer is, out with the reciprocating saw and cut it all up into manageable pieces. Crying shame as it is in really good nick. I was only asking $1,500 and only got two bites, but it would only take something to go wrong with removing the sliding door etc that everything I make on the sale could go out the door on repairs etc. It would have been nice to be able to turn it into tools etc, but que sera sera. I don't know about the rest of the world, but there just seems to be very little interest from people wanting to buy things secondhand.
