Bought for my wife who is in nursing school. She works the night shift at the hospital. The date doesn't change until 3-4 am. The problem is when you're dealing with patients and you get tired in the middle of the night shift. If you look at the clock and it says Thursday, you are planning on the wrong day. Plus it's an amazing watch she loves it. She wears them instead of an Apple Watch. Eliminate this problem and you have the perfect watch for breastfeeding moms.
