Ronstan

Q: The beeps on the one I just bought are audible but just barely. Wondering if that is normal or whether I should return for a replacement?

It’s not loud enough in a keelboat cockpit

Q: can i set it up as a 3-2-1-0 minute timer?

Yes, but the timer is awkward to use. I use and really like the Gil timer which is much better.

Q: How long does the battery last?

Our battery has lasted years with lots of use

Q: Is the watch water proof and to what depth

I don't recall exactly, but if you roll your dinghy or go for a swim it'd be fine. If you're planning on using it as a dive watch, I think you should buy a dive watch.
