When the sea visit your watch...

[Porter]

Hi all,
I recently bought two beautiful movements, 1520 and 3000. I bought them not only because are amazing machines the truth is I bought them because are nearly dead!!
I'll try to restore them and afterwards try to find a new case to pass the following years!!
The 1520 will be the first to try to restore! Here is the pic just after opening the box from the seller:

Is seriously damaged! More than expected!! First eyeshot goes to the balance wheel. Rust eat the spring!! So... Will need new spring! Before getting mad I take the movement to the ultrasonic machine and introduced in different cleaning liquids! Here is the result:
Now is a bit better...
Tomorrow I'll check all screws and start trying to unscrew them. I want to save them as much as possible but probably will brake a lot...
To be continued...
NOTE: Sorry if I cannot explain in correct words but I'm not costumed to explain my work to anyone in any language!. All corrections are welcome!!
