This book is the comprehensive standard on Seiko dive watches!
Although a japan language publication, the photos are quite informative and give a narrative of the topic by themselves. Some English text would have been helpful to get the full message intended by the authors/publishers. However this is the only publication I could find on this topic anywhere. I think it is a useful resource for anyone with an interest in the best Seiko has to offer in dive watches and their approach to these types of watches. This book is the comprehensive standard on Seiko dive watches!
