Fantastic!  So, because I was an early user of the GlucoWatch, Cygnus has sent me a

GlucoWatch G2!  The G2 is a refinement of the GlucoWatch, and actually gets closer to my initial expectations. 

I was disappointed with the original GlucoWatch because it skipped records often. Even though it tried to deliver blood sugar results every 20 minutes, when you factored in skipped records (for whatever reasons, sweat, temperature, etc), you'd be lucky to get 1 or 2 an hour.  Also, the original GlucoWatch had a nearly 3 hour warmup period and would operate for 12 hours.  Often it would give up around hour 7 or 8 and be done for that period. 

The GlucoWatch G2 Biographer's most notable enhancements over the first-generation GlucoWatch Biographer include the following:

• It measures and displays glucose levels automatically and stores readings up to every 10 minutes – twice as frequently as the first-generation product.
• It provides readings for up to 13 hours a day – up from 12 hours in the first version.
• It also creates an "electronic diary," storing up to 8,500 glucose values – compared to 4,000 in the first version – that can be reviewed, or uploaded into a software program, helping detect trends and track patterns in glucose levels.

Getting results every 10 minutes almost makes diabetes bearable.  (Almost)  It's amazing to watch my blood sugar over a 3 or 4 hour period after a meal go up, then back down again.  We're talking about 20-30 readings.  That's just not possible with a finger stick (I'd run out of fingers!)

Conclusion: The G2 is the watch the original GlucoWatch should have been.
