Hiya, Steve.

dustmite posted a fuller explanation of what the 'watches' actually were on another thread. He said:

These 'watches' that you refer to are known as 'Acti-watches'. An Acti-Watch is an actigraphy-based data logger. Basically, actigraphy is a way that sleep patterns, quality, etc are assessed and monitored.

They technically record:

Sleep/Wake Patterns
Sleep Disorders
Circadian Rhythms Disorders
Basic Activity Levels
Compliance with Exercise Routines

Clever, eh?
