It cannot be used in low light or dark (like night time) as neither the arms or numbers glow in the dark no matter how much light they've been in, for me this makes it useless as much of my time is spent in low light. For this type of watch and its cost low light and night use should have been considered. Also the clasp that holds the winding mechanism comes lose and opens making it a possible breaking point and annoying. If my kids hadn't picked this watch out for me I would have returned it. I will wear it until they forget about it and put it in a draw, sell it or goodwill it for the tax right off. The seller/ vendor was amazing and this does not reflect upon them. Harding should have done better.
