I love mine! Complications include an analog compass, tide tracker, and air/water temp gauge.

Good luck! Great watch, too.🎯

This is super cool with the internal bezel. Does the top crown rotate it?

OMG! I wanted one of these sooo bad in 5th grade! Is this vintage or do they still make them?

Thanks, I built it based on a US Military Specification GG-W-113 dial that I found on Yobokies. Then after researching it, found that the Marathon GSAR executed it very well with a Rolex sub style case and figured if they can, I can.
