I recently purchased this Tiffany watch and am wondering what the next steps should be. I purchased it to wear, not to sell. The movement is Movado Cal.470, 17 jewels. When taking this to be serviced, should I go to Tiffany, Movado, or to a reputable watch maker? Also, I should not have any retouching done on the dial to the calendar days that have rubbed off, correct. The one hand is missing the center panel, is that something I should be having replaced. Just trying to avoid any missteps here. Thank you in advance for your help!
