Croton Nivada Grenchen Men's Wristwatch. Back case of the Watch is not marked but I believe it could possibly be Gold. I don't have the proper tool to remove the back so I don't know what the inside says. Face of the Watch has what I believe are called diamond accents. I've had the Watch running for a couple of hours and it appears to keep accurate time. Crystal face is pretty clear. Light scratching is visible when held at an angle to the light. Back casing seems to have a "yellow gold" tint but again no markings. Some light scratching and small section on the edge where it looks as if someone may have tried to remove the back. The back of the Watchband is marked U.S.A. I'm selling the Watch "AS IS" so if you additional questions or need more photos please ask in advance. Buyer to pay $7.50 for shipping & insurance within the U.S.
