Vintage Restoration Question

Hello All,

New to the group and would value your input. I just obtained a Stainless Omega Constellation (Pie Pan). I found it at an estate sale and while it runs accurately the crystal is well used and clearly I have no idea when it was last serviced. I am wondering if there are any thoughts with regard to the best shops to undertake restoration of vintage watches ( I am located near Seattle)? I am interested in patina and not looking to disturb the value of my vintage watches via over restoration, but I do want to work with someone I can trust. Any thoughts, suggestions, etc., would be greatly appreciated.

Thank you that is much appreciated!

I've heard good things about Nesbit's in Seattle, although I haven't used them personally.

Anytime you can hand-deliver a watch for service, I think it's worth it versus having to mail. Too many things to go wrong when shipping.
