Wonderful luv it my sound strange but I don't dive when I saw it had to get caught it
The 38 (blue/red) is less expensive and It is less bulky, but I have not had the 29 (black) in my hand I have average-sized wrists, perhaps even a bit smaller, and this watch barely fits ... It would be too small for a lot of people. I haven't been on a dive with it yet, so I can't comment on the ascent alarm
Watch feels and looks great. Easy to use. Charges in sunlight quickly. The Blue Strap that it comes with is a little smaller than previous models (could be one inch longer). Otherwise, very nice timepiece.
Love the watch. Hate the band. I have small wrists and I use up to⁸ the second to last hole.
