浪琴，精細及吸引，不銹鋼腕錶，配飛返計時功能，型號6592-5，約1963年製

The Longines calibre 30CH is renowned among collectors as being the successor to the legendary 13ZN fly back chronograph movement. The flyback allows for the quick resetting and running with the push of 1 button rather than the 3 presses required with a standard chronograph, which is especially useful when timing multiple evens in quick succession. This reference 6592 features luminous accents to the dial and hands to improve low visibility.
