The oldest model of the selection is by Longines. The 13ZN chronograph came to the market in 1936 and features the so-called flyback function. Thanks to this complication, the watch wearer was able to use the chronograph's stopwatch function without having to stop and restart the dial's time display.

To the 1960's, a Rolex Daytona Chronograph from 1962. The stainless steel model has the reference number 6239, the same as Paul Newman's Rolex Daytona that sold at Phillips last month for a staggering $17.8 million.

In 1947, the Swiss watch manufacturer Vulcain launched the first wristwatch with built-in alarm clock. The alarm tone sounded like the chirp of a cricket, which is how it adopted the name "Cricket". Since then, the watch has been worn by many US presidents, earning it the name "President's Watch".

The colourful Stella dials, available in a variety of colours, were used in the 1970s and 1980s for Rolex Day-Date models. One story claims it is named after American artist Frank Stella (b.1936) as it was inspired by one of his works of art. Another story claims it is named after the Latin word "stella" for "star."
