I'm selling my Longines Hydroconquest (L3.218.104.22.168) which I bought in Germany back in 2010. Watch has been taken very good care of by myself. Never dropped, serviced every 2 years, etc. Asking $750 shipped CONUS. Comes with box, manual, and papers. Insured USPS. PP only. Please don't hesitate to ask me any questions!
Here are pics of the watch. Normal wear. But upkeep has been good in terms of servicing. Keeps time impeccable (+-2 second per day).
