by a friend in New Zealand who tested it on his GPS system at room temp and wrist temp....
This is a dual oscillator crystals model and rated back in 1987/88 by Omega as a +-10 secs/YEAR accuracy watch. This model can be owner regulated....
The test showed that if worn 24 hours on wrist, it would average out to under 5secs/YEAR accuracy!
If taken off during the nite, the watch, temperature sensitive, would slow to under 10secs/year....
Not too shabby for an old watch!
In fact it sounds
