I'm an estate jeweler and watch dealer so I've had a number of dive watches come through and been able to test them as divers... Here's my take on things...
I always dive with a watch as a backup timer. I set the bezel before descending so I know how long I've been down. Also handy to know the time of day on occasion (My dive computer doesn't show the time of day on it's main screen)
My personal Omega is dive capable but is too expensive to take on trips and too expensive to risk loosing/flooding.
I don't keep Rolex's for personal use as they're too expensive and easy to sell... keeps the money flowing.
I have a Tissot Sea Touch... what a pain in the ass to use, even above water. Been trying to sell it for years.
I have a Citizen Eco ProMaster Depth Diver. I like the redundancy of both a timer and depth gauge but the big problem with these is keeping it charged, You have to keep it in the light to maintain the charge. This is fine if you wear it daily (it's a bit bulky for that) and dive often but for occasional use it's a bit of a pain. A couple of times I've forgotten to take it out of the dive bag when I get home and it doesn't maintain enough of a charge to operate the depth gauge the next time I'm going diving. Takes a long while in the sun to get up to dive level charge.
Then a Seiko Prospex (PADI branded) came in one day... favourite dive watch of the lot. Small enough to wear as a daily, non-blingy so it's reasonable to take on vacation and even brand new from a dealer it's a three figure watch. When I'm not wearing it it goes on the winder with my Eternamatic, Omega and Tudor so it stays wound and running.
My daily is another Citizen Eco (but with daily time sync to the atomic clock in CO). I use this one so I always know the precise time and use it to set all my mechanicals lol. Four watches on the winder and after a couple of weeks they all have a different idea of the time. It's not dive rated but I did forget one day and wore it to the bottom of Angelita... not a problem.
I'll stick to an automatic Seiko for diving from now on. Great quality, safe to travel with, reasonable purchase/resale price point and is as sturdy as anything from Rolex or Omega.
