Have had other "less capable versions", once set up takes care of itself as long as exposed to enough light via charger at night.
I’ve had this watch for over 6 years. It works as well now as when new. Due to the years of almost daily wear it definitely shows the superficial wear and tear of an adventurist lifestyle, but the crystal is unmarred, the face as clear and looks brand new. If you want a watch that works long and hard through all kinds of conditions, never needs to be adjusted or serviced, I highly recommend it.
I'm really pleased with the watch. The band sizing option worked quite well and the watch band needed no further adjustment. The watch eliminates my biggest hassle with calendar watches with the sync to WWV time/date. The dial is a bit busy and the markings a bit small for my aged eyes but overall I'm very pleased. The order, ship and receive process was painless and quick.
