Hi, I am a watch novice, but have noticed that I really like the aesthetic style of dive watches. It sounds like Debaufre offers some good quality/reasonably priced dive watches, so I have been exploring their website. What are the differences between the Ocean-1 and the GMT Ocean-1? As far as I can tell, the only difference is the dual time zone capability of the GMT. Are the movements of equal quality? Why is the GMT so much more expensive? I don't really travel to other time zones often, so this would not be a big selling point personally.
