I never understood the fascination with a watch for insane accuracy.
If you measure how good your watch is by how accurately it keeps the time after x amount of time passes, why not get a watch which updates automatically?
My watch is solely an accessory, for looks because lets face it, most of us will look at our phones FAR MORE than look at our watch throughout the day.
OP did you copy and paste that watch advert or did you fall for their marketing so much that are now advertising for them?
