Dust under crystal

[newwatchguy]

I just received a PAM351 (KW v2) from Toro and it's perfect except a big fleck of dust is sticked to the crystal. Looking at it from an angle it looks like dust but I'm not sure if it could possibly be a tiny chip to the crystal or something else.

What's my best option to get rid of it? If I take it to a repair shop, is it gonna be a quick and easy job or will it cost me a lot?

Please advise. Thanks much!

Go to the the 6497 movement section on the forums, there is a guide on how to remove the movement to get access to crystal. Very easy. All you need are screwdrivers.
