I really have to give it up to the AD guys, or at least the person who put my watch together...
I've been timing my BS 300 for the past 3 days now, comparing it to the time on my cell phone.
At first I didnt believe it when I timed it for a day, but now three days later, the watch has been running TO THE SECOND compared to Verizon time!
I will keep track for the rest of the week to see if it deviated at all.
I'm very impressed. This has been the best watch purchase I've made in a while....and I buy 2-3 watches a year!
I'm loving this watch more and more each day!
All other BS 300 other please chime in...
