Removing the rotor from auto watch

[supercommuter]

Hi - I have a cheap Parnis watch that I really like the look of but never gets any wrist time as the rotor is so loud. Given I can hand wind the power reserve up I would like to just remove the rotor and have it as a manual wind.

I have no experience of working on watches and given its a cheap one I am contemplating spending £5 on a tool kit from Ebay and removing the rotor.

How hard is it to do? Am I going to remove a screw and the whole thing fall apart on me?

Fix it instead.

Apparently the movement is well known to be noisy. People have added a drop of watch oil etc. and its made no difference. Unsure as to how i could repair it?

In case anybody cared or was curious. I purchased a £5 kit off of eBay and had a go. Once i removed the back there were 3 small screws holding the rotor on. I took them out and gently removed the rotor. Now a manual wind without the horrid noise!

Only thing to be aware of is if the movement is a 7750 or Asian clone of a 7750 they can be easily damaged by hand winding - the gears are fairly well known to strip.

It's not a 7750 clone (something like a TY2551 by the look of it). Valid point about the manual winding, although having no auto weight on there will reduce the risk quite a bit because the reverser wheels will spin easily with no weight to provide resistance.

If you want to finish the job for maximum reliability, remove the auto works complete. Look carefully and you'll see 3 screws holding the central "lump" onto the movement. Remove those and lift the auto work off, you then have a pure hand-wind movement with no extra resistance at all.

Thanks - I will open it back up when I get some time and try my hand at removing the auto bits.

To be honest its a cheap watch that I wear with a suit so I don't have a shiny metal seamaster poking out of my cuff when i'm in the office - given I am at home most of the time it won't get used that much!
