Hey everyone. I'm trying to learn what I can about the inner workings of what makes a watch tick and am wondering what might have happened to the 552 movement up for auction on the Bay.

The rotor looks like @ss and I am wondering if that is corrosion due to water or moisture damage. Can the experts chime in? I really want to learn so that when I decide to go for some vintage pieces I have at least a bit of working knowledge.

Just looks like fingerprints and light scratches to me. Macro photography can really magnify imperfections.

It was written by a dummy.

 

I see what you did there.

 

Here's a bumper that had moisture get into the case:



Now that's a corroded rotor. The green stuff cleaned off during a service, but it left the copper plating damaged and discolored.


Here's another bumper that the copper washed off of, probably because too harsh of a cleaning agent was used during one service.

 

Pure curiosity: Which avatar do you like better - the "Omega Recycling" one I use here or the "Out of Focus" one I use there?

 

I like this one, because the other one hurts my brain. However, the reason might be due to me polishing off half a bottle of laphroaig 18 this evening...

 

I like your old one, you know, the one with BANNED under it on most sites

 

So is the bottle half empty, or half full, or are you half full

 

I'm half full, the bottle is half empty, and the mrs has hid my wallet so I don't go on an ebay spree. Damn good woman I have.

 

The reason I wonder about this one is the rotor. That looks more like neglect or some kind of gunk or dirt or corrosion than fingerprints. I asked the seller but his English language response was lacking.

The engineer says "The bottle is twice as big as it needs to be".
