Had to look hard to find it again
My husband loves this watch. This is his second one, and it was hard to find this one, exactly like the last one - which lasted for years. Good overall watch, easy to read, reliable.

POOR PACKAGING
Disappointed that the watch arrived only in plastic bag without bubble wrap envelope. The plastic box was broken and the paper box old , I bought it for my father as a gift, and I had to buy other box because it seemed like used. Good: it arrived on time.
The watch is really nice and functions well.
BE CAREFUL WITH PACKAGING!!!

Don't buy its a waste.
Very cheap watch. Sharp edges and adjustment of the band although easy to do, the parts are very flimsy. Don't wase your money.
