This is a very rare 1950's Swiss made Fludo Chronograph vintage watch.  The original case has a serial number showing 6113 and is made of solid stainless steel.  The crystal on this watch is brand new.  The case has a measurement of 36.3mm in diameter excluding the crown by 44.4mm length from lug to lug.  The factory original dial is absolutely gorgeous and has been nicely aged.  The watch takes a clean manual wind Landeron 51 movement which is running strong and keeping very accurate time.  The chronograph is in good working order.  A very attractive and fine quality vintage chronograph watch for a very good price.
