Hey Hal,
Symetricom need sales and investment in this product, to get back the R&D costs.
I believe this is the first Gen?
If they get the volume the price has to drop.
However, It is a bit sucky marketing can get away with that.
I wonder if they have good and bad CSAC a la Crystal oscillators or I haven't grasped the importance of this yet :)

Practical?
What's the battery life? How accurately can you read a watch dial?
How good are modern watches? How do crystals compare with mechanical? Where is the crossover point between watch accuracy and human read-it accuracy? Is that before or after the CASC watch runs out of battery?
I suppose you could put it on the charger every night, next to your cell phone, but then I could make a crystal watch that connects to a "charger"
stand that also sets the time.
