I ordered this watch because it was cheap and looked nice. This is the worst watch I've ever had. The mechanism stops and starts randomly, so it loses 15 minutes here, 30 minutes there. I'm a scientist and this clock messed up 2 of my experiments by accidentally stopping or showing the wrong reaction start time. I ordered a replacement thinking a cheap item might save on quality control so I'm giving them another chance to give me a decent product. The replacement watch strap fell apart and fell off my wrist after only wearing it for a few days and I can't put it back together. Please save yourself the hassle and purchase another product instead.
