The watch has worked well though there are two distinct negatives. One - the extremely weak glow on the watch face making it nearly impossible to read in the dark despite long hours under light beforehand. Two - the watch band is made of a poor quality polyurethane rubber that has quickly deteriorated and cracked/broke off within less than one year. I have not found a replacement and the advertised one is about $75.00. That is an expensive annual expense.
