Device for converting a number from one unit to another unit, and particularly an amount from one currency to another currency

摘要

The converter (1) is configured as a wristwatch and has two liquid crystal screens (11,12) on the face (10). The screens normally display time and date but combinations of pressure on the buttons (14,15) or use of an additional button (13) enable conversion and quantities such as francs or Euros to be entered and validated. The converted value is shown on the screen.
