Watch will not maintain accurate time. The slightest vibrations cause second hand, minute hand, and day of the week pointer to displace resulting in a re-zeroing procedure to be necessary for these indicators. It is a lengthy process. The atomic clock feature does not correct the problem. I do not recommend this or any other watch with this problem.
I have had this watch for 2 years. It took me a long time to find the "right watch". Love the colors and it works great 100% of the time.
