Hmmm. I set mine going too. Battery charge is showing full, although it
had been used for an hour or so. The unit gained approximately two
seconds in one hour and twenty minutes. This is clearly surprising in
view of today's quartz technology. It doesn't affect me in the slightest
because I don't use it to sync to other devices, and prior knowledge
wouldn't have affected my decision to buy. I just find it odd.
