The Omega Marine Chronometer was the first wristwatch ever to be awarded certified status as a Marine Chronometer. The watch was made by Omega SA and developed by John Othenin-Girard and is one of the most accurate non thermo-compensated production watches ever made, keeping time to within 1 second per month 〔http://doensen.home.xs4all.nl/j30.html〕 ==Introduction== The watch was introduced to the market in 1974 under calibre 1511, having an unrivalled accuracy of 12 seconds per year thanks to the revolutionary 2.4 MHz quartz circuit.〔Lucien F.

ISBN ISBN 9780764343049〕 in 1976 the calibre 1516 Marine Chronometer was introduced with smaller case dimensions and altered movement, although performance remained the same, sales began in 1974 and the watch remained in Omega line up until 1978.
