I dove a freshwater cave system this weekend and decided to take a few 200m dive watches with me for the hell of it. There was no method to this and I was really testing a GoPro and new light set up with filter to see how the correct the colors were.

The watches I brought along:
Casio PAG-60
Seiko SRP453
Citizen JV0030-01E
Oceanic OC1 (dive computer watch)
I took all of them down to 123 feet and 131 feet and all functioned without any issues. (they are all rated to 200m so I expected no issues) The Citizen and Oceanic data matched except for a 3 degree difference in water temp. The Oceanic is accurate and the Citizen ran a little higher. The JV0030-01E is a phenomenal watch. It continues to impress me every time I dive with it. The Casio worked like a champ and was accurate to temperature and compass (match to a spg compass). The Casio's depth gauge would not register a negative depth at 92 feet and showed ----- on the display. It does register correctly +/- 20 ft per the specifications when not at depth. The Seiko just looks good on your wrist when it's underwater. The lume is a torch and is the best of all the watches for both brightness and duration.
Here is a quick 1:30 video showing the dive and Citizen and Seiko watches. Casio was hard to video as it won't lay flat due to it's band design and Oceanic is on my wrist as it's my primary dive computer. For safety reason I won't remove it at these depths in a cave. I kept the dive at the 130ish range and did not go to the 140ish range as the area had so much silt that any movement in the silt creates a silt out and makes visibly almost zero.
