I have a used M51 with 4 bands & box cards, paperwork etc. It has a scratch on the right hand side you can see in the pictures on the side of the bezel. No scratchs on the front or back side crystal. It keeps awesome time and the lume glows awesome. Has a one off red second hand. Im now putting some scratch together for a trip in a few week so this one is on the chopping block. 275.00 via paypal shipped USPS with DC. And thats a outright steal!
