24h clock is ugly, you missed :
16 years in the Marine Corps and I agree with you the ":" or Colon in the real world is not needed. My only ding is not being able to calibrate compass or elevation. Compared to my trusty Lensatic compass it's off by 8 degrees on the trails behind my home. Yes I have this written down and include it in my declination correction from magnetic North but it would still be nice to adjust on the watch and make the corrections in the watch and set true north. Also my home is exactly 752 feet above sea level and the watch reads between 708 and 711 between the last few hours. I know there will be slight changes do to pressure changes but it would be nice to zero it out at a known elevation before leaving the house. All and all awesome watch face thank you!
