Reviews
Big Fan of Attesa Watches
I am a big fan of the Attesa line of watches, including this one, which is especially stunning. It has unparalleled beauty and craftmanship. I own several Attesa watches including the satellite timepieces. What I like about the atomic timekeeping watches is that they self-calibrate once a day (about 2 am) without any intervention from the user. The satellite watches will also self-calibrate once every 6 days (I believe) only if exposed to a clear overhead sky. Otherwise, a manually induced calibration outdoors is need. I have had some issues with the adjustment of the band provided by Citizen. I use a fabric tape measure draped loosely around the wrist, yet for about half of my watches, the adjustment provided is too tight.
