–Rolex microstella tool came in. Adjusted Turn-O-Graph from +10 s/d to 0 s/d. Seemed to lose a little amplitude (though it’s outstanding for a watch that old) and beat error went from .1 to.3. Not bad for the first time.
–Took a bike ride. Odometer seemed off in wrong direction after (second) adjustment. Perhaps due to less-inflated tires. I don’t recall that was a huge issue way back when.
–Pool is 73. Yes!
