I have the Gulfman G9100-1
Its one of the best watches that I’ve ever owned.
The time keeping ability of this watch is outstanding.
I could not believe how accurate it truly is.
I hacked the watch against the Naval Atomic Clock
http://www.time.gov/timezone.cgi?Eastern/d/-5/java
It is exactly hacked against the display on the computer which has a less then .02 second lag. The watch has been perfectly synced with the time on my computer display for over a week.
The tide and moon graph is exceptional and extremely useful for me as I use it to know when the tides are low so I can run my metal detector on the beach as well as other hobbies.
The world time feature lets me know what time it is in Australia and other parts of the world when I’m on the Ham Radio.
Its a great looking watch, its not the most comfortable but it is very light. I assume my issue with the watch not staying centered on my wrist is simply that it needs to be worn and broke in a bit. All they need to do to improve this version of this watch would be to make this one solar powered
and Atomically set for time like a small handful of the others that they make. They could offer this watch with some other color variation or a reverse display such as the Gw7900. I’d have to give this watch a solid 9.5 of 10.
