Hello, Selling a desirable U50 Professional toay. From the Watchbuys site, here are the differences compared to the regular U50: \-First Sinn U50 to feature a domed sapphire crystal rather than flat for superior water resistance and legibility \-First Sinn U50 to relocate the crown to the left side of the case as Sinn does with many of their Mission Timer EZM special forces watches \-First Sinn U50 to feature white BGW9 Super Luminova for superior visibility and lume at night (BGW9 has a relative brightness of 300% higher than the C1 used on the standard Sinn U50) \-First Sinn U50 with time only display (no date) for clean layout and improved legibility \-First Sinn U50 designed with the color scheme featured in the Sinn EZM 1 The watch itself runs great as expected, and the head of the watch has no scratches or marks. I pulled the bracelet off my old U50, so be aware there is a mark on the clasp it had gotten from getting scratched against pavement. Asking for $3400 PayPal G&S only. Not looking for a profit on this one, just wanted to recoup my money, so selling it for what I got it for. This is the lowest one of these has been listed for. Since this is a desirable watch for Sinn collectors, I'm going to wait a day or two before finalizing the sale so that everyone can get a chance to see this. This was a US exclusive for the north american market, and only 150 of them had been made. If you have any questions let me know :) (and sorry no trades) Photos: https://imgur.com/a/IUC2LT0 Timestamp: https://imgur.com/a/YFOCjMf
