Further to the interesting Seiko & Citizen Watch Forum (SCWF) mentioned below, there’s a very active group of Seiko watch fans on Facebook.
It’s the Seiko & Grand Seiko Watch Fans group, and you’ll find them here: Seiko & Grand Seiko Watch Fans
Please note. It’s a public group so you don’t have have to apply for membership first before being able to see the content. As well, anybody can see what you might post in the group..
