The final decade of the last century saw Omega's only jump hour . . .
. . . and perpetual calendar wrist watches. I've no idea if there were Omega jump or perpetual pocket watches, but would be surprised to learn they actually existed.
Omega made a dead seconds watch in the '40s but recalled them due to consistent reports of unreliability. If you should find an Omega cal 372, jump on it.
