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 wore it a few times after 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 the blue light that came with the purchase. Regarding the strap, I used one I bought commercially. The original strap is not included. Thank you. ※ Immediate purchase OK! ※ Comments OK!
