A winner: Jaeger Lecoultre Master Tourbillon.
Winner of the 2009 Chronometry Contest. I wish we have more of these contests, in the future. Best, Nicolas ...
A properly adjusted mechanical watch can be as precise as any other. It just takes time and patience for the watchmaker to adjust it properly.
Anything else is just an excuse or subterfuge. I have a few watches that keep almost perfect time.
