Dear all, I am looking for a NOS or used "Indicator Dial Ring" for my Seiko 6117-6400 World Timer. It is a Seiko part No. 89999810 (it is a white plastic ring with little teeth that sits below the upper place-name ring and makes it rotate). If you have one for sale or know where I could get one, I would be very grateful to hear from you. Many thanks. Vojtech
