Footnotes

This watch combines three features that make it a milestone in the production of Rolex watches. It was designed for scientific use with a need for accuracy so it has a chronometer movement. The seconds hand is mounted in the centre to give a clear indication of the 5ths of a second that the dial is calibrated to, this is powered indirectly from the movement with an extra train of wheels. It has an 'exotic' dial rare and unusual in its Scientific configuration. Lastly it is cased in an Oyster Watch Company 'Oyster' style case typical for what followed and came to be known as the 'tool' watches for professional use.
