Hello, My grandfather passed away in December and my father is now in possession of his Omega Contellation. My father is not a watch person but I want to get it restored for him. I will post my poorly taken pictures with this initial post and take better pictures later today. It is stainless steel has a black dial and the 564 movement. The watch itself still functions however the date can not be changed through crown adjustments. My questions: Should I have Omega service/restore it? What can I expect to pay to have them do it? Will it alter the value/rarity of the watch to have certain things done or not done to it? How can I know if a watchmaker is qualified and/or trustworthy to work on the watch and not take advantage of me? Additionally as I was researching I contacted Quality Vintage Timepieces and they told me to not have anyone touch the dial because it is rare. They are also considering servicing/restoring it for me(I am send thing them the same pictures I will post later on this thread). -has anyone had their watches serviced by QVT? TL;DR -1967 Omega Constellation Black Dial 564 movement -how much to get serviced? -Serviced by omega or are others(Quality Vintage Timpieces in Toronto, Canada) okay? -How much will this cost me? I am located in Buffalo, NY and don't know of any watch experts in my immediate area. Thank you, Jake PS. I know that is not the original band, it is a Speidel Twist-o-flex I plan on replacing.
