For a second I thought that Meistersinger had made a watch that I have imagined for a long time: An einzeiger one-handed dive watch. But this is some sort of gimmicky watch where the one hand is a minute rather than an hour hand.
An einzeiger dive watch would be hilarious. I love dive watches and I love einzeigers. In theory dive watches allow you to time your dive and not run out of oxygen, and the bezel helps you. With an einzeiger dive watch, presumably the bezel would be denominated in hours, not minutes. It would be spectacularly innacurate and hard to read while diving. It might kill you. That's the watch I want!

Far more practical than a traditional einzeiger, especially for the purpose intended (diving).
Nothing gimmicky about it.
As for watches that will kill you--maybe next drop.
