How is case corrosion fixed/stabilized?
Hi, I am bringing my 5500 AK to be overhauled next week at Central Watch. The watch has some corrosion on the case frame(where the case back gasket joins the rest of the case). I was told that this can be fixed in a service. How is it done? Hoping CW doesn't charge an arm and a leg.

It is a welding technique where new material is filled into the corroded 'holes'.

I would only have it fixed if the pitting compromises the water-resistance. |

-if condensation appears on the inside of the crystal it s necessarily means that water got into the case or just servicing(or just opening/closing) in a humid enviroment is enough to experience such a thing later -if water got into the case then condensation will appear for sure or could such a damage remain "silent" until next service -obviously we talk about a small amount of fresh water not a massive seawater intrusion. thanks

Ive done work like this. Depending on the extent of the damage it can be as little as $50 but could also cost hundreds of dollars.

Easiest way to explain the excess metal is polished off and as a result you get a smooth surface.
Here's an AP we did last month. https://www.instagram.com/p/Bc8lByLh...tchcentral_nyc |

Well a company doing mediocre polishing wouldn't bother laser welding haha
This job was around $700. To clarify, its $350 for refinish, and $350 for the laser repair. |

Bas , you as watchmaker considering a cleaned watch movement (after water damage or slight corrosion ) equal to one which never had such an impact , if the balance and escapment is intact (or replaced) such a watch could have the same accuracy as the other?

As a matter of fact, I bought a vintage Omega a few years ago with water damage, serviced it and all is good |
