E. M. T. It has a jewelled movement with no markings except the regulator scale marked ‘A R’ and ‘F S’. There is a club-tooth ever escapement and a two-arm compensation balance. The movement is housed in an open-face stainless-steel case with a screw-on back, bezel and glass. The back is marked inside ‘SWISS / STAINLESS STEEL / 99653’, outside ‘99653’ and the broad arrow. A pull-out hand-setting winding crown is at the XII-position.

A white enamel dial has Roman hour numerals, with Arabic five-minute/second figures outside. There are centre-seconds and no inscriptions on the dial.

The watch is housed in a wooden deck box with a hinged lid opening to 180°. The box has a flip-catch to lock, it is lined with green baize and includes a brass label-holder (empty). The watch sits in a circular green-baize-lined aperture in the base of the box and can be seen through a circular porthole glass window when the lid is closed. The underside of the box is covered in green baize.

E. M. T. was a Swiss maker of high-grade commercial lever-escapement pocket watches, which during and after the Second World War, were obtained by the UK Government and re-cased in stainless steel to meet demands. They were additionally housed in wooden deck watch boxes manufactured by the Admiralty chronometer workshops. In the 1950s and 1960s many were sent to Karachi for use by the Pakistan Navy, with others being dispersed to India, Egypt and the Republic of Ireland.
