Dark Face

the watch is too hard to read. it needs more of a contrast, hands vs face.

Buyer Beware! This appeared to be a used watch.

The Tin had a predominant dent . Open the tin and the G-Shock wasn't wrap nor did the face have the standard protective film. There was a tag representing the sellers business affixed to the bracelet and 0 paperwork included. Upon inspecting the watch there were several small scratches on the bezel and the bracelet. If this was for me I probably would have kept it solely on the cost, but because It was a graduate gifting , it would have been an embarrassment. Sent back 10 minutes after opening and buyer did good with a quick refund. Buyer really just needs to be honest as there is a market for used watches - but to deceive the consumer is on a whole different level. Hope this helps someone.
