For sale only an early 70s vintage Sinn Navitimer similar to Breitling 7806. Probably the first variant of the 903 series. Watch is in very good condition for its age, plexiglass has no scratches, case has very minimal swirls, case back has a scratch but not deep. Dial hour markers darken due to age. Case size is 41mm without crown, 22mm lug width. Comes on a used Breitling strap.
Mechanically sound, chronograph resets perfectly, good power reserve about 30+ hours when fully wound, timekeeping at -7s per day.
No quickset date, good old 2100-0000 for date change. Date appears slightly toward right.
USD4200 including registered shipping and PayPal Fees, other shipping arrangement to be discussed. Pls pm for details.
