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.
