The 1960s saw many memorable moments for Timex. Cases and dials were larger, There were significantly more models produced with automatic, calendar and day-date complications and movements transitioned from the m21 and m22 to the asrguably more servicable m24/5/7 and m31/2/3 calibers.
The 1960s saw the production of one of my favourite Timex, the Skindiver which was produced with a calendar complication and 25 meter (60ft) depth rating, and the in my opinion superior all steel 600 feet (180m) version.
Other collectors favorites released in the 1960s include the 100 range, Bayonet, 400 series, black dialled sprite and last but not least the Marlin model that was so popular, Timex reissued.
