Affordable, comfortable, and practical watch
Color: Gold Silver Stainless Steel/Green Dial-2870, Color: Gold Silver Stainless Steel/Green Dial-2870
This watch is very good for its price range, of course this isn’t a Seiko, but what do you expect for under $50. I’m extremely excited about this watch and just finished removing some links for it to fit. That’s the worst part removing the links which is very difficult even with the tool that was supplied. Now, we’ll see how long the watch will last and hold up after everyday being worn. It’s a good looking and comfortable watch that’s inexpensive.

Used Watch?
Color: Black/Gray/Digital
The watch is great but the watch had been worn. The protective film was removed and it was loose in the watch box and not on the plastic holder. I bought a new watch not a used one. Joe
