Watermark on watch dial, where to fix?

[Lurch]

I found out there are 2 possible water 'dots' on my watch dial.
Anyone know where can I fix/clean it?
The dots are very small but noticeable under close watch.
Went to txx Amcorp who said they were unable to clean it coz
it might possibly tarnish the White dial

Seems like a straight forward job, remove the glass and clean it off but i don't know..

Thanks alot

could you upload some pics?

Will try to upload but not sure whether can my hp capture the fine dot...
Any service centres that might fix this?

the mark is too small... my hp camera could not capture it.
basically just need someone to open the crystal and wipe it off... wonder why txx declined to do it

U may try the bag method but remember to Unscrew your crown for vapor however I ll suggest u to send it to service center to service the watch bcos u wouldn't know this moist cause any damage to the movement
