PO: accurate, beautiful, expensive -- but can't dive

Going to send it to an authorized/qualified Omega watch-smith to put it 100% right.

PS Dove the 1898 wreck of the steamer L.R. Doty last Saturday, 306 feet (100m) down on the bottom of Lake Michigan, water temp 37 degrees F, run-time of 131 minutes. Took the Rolex Sub along for the ride, and no problem at all. I look forward to christening the PO with the same success after it's serviced.

I think you're on the right track here. Sounds like it's a lubrication issue.
