The watch is very accurate. The battery lasts well for 2 years if you do not constantly try all functions. In my weekly sauna visits, I put the clock not starting. The clock does not harm themselves swimming. However, the band breaks by many sauna passes through the intense heat of infusions. A replacement belt costs as much as a new clock. My 1st clock is with a defective tape, because the time is easy to read, next to my PC printer. The 2nd clock I ordered running smoothly. Since I no longer occasions the clock for a swim and sauna I complain about anything to her.
