This is an Omega Swatch. I purchased it at Hankyu in Kobe previously. Purchased in August. I am selling it because I no longer need it. It comes with a 2-year warranty. I've worn it a few times since purchasing it, but I don't see any scratches or stains. Please understand that this is based on my personal observation. The box, instruction manual, and warranty details are all included. I will also include a blue light that I received when I purchased it. Regarding the strap, I used one that I purchased commercially. The original strap is not included. Thank you. *Immediate purchase OK! *Comments OK!
