Notes

The present watch has an interesting and simple mechanism for independently adjusting both pairs of hands. A slide on the band can be moved one way to engage the hand-setting for one dial and then the other way to set the hands of the other dial. This watch is rare in having two time-zones and thermometer, it was intended for use on the railways, the home station being Calcutta.
