The Black Watch was launched in September 1975 by Sinclair Radionics, later Sinclair Research, the company behind the ZX81 and ZX Spectrum.  It cost £24.95 ready-built or £17.95 as a kit.  It had a red LED display and was marketed by the company as follows:

'if that [the technical description] sounds technical, think of the outcome: a watch with no moving parts, a watch with nothing to go wrong, a watch which gives accuracy never achievable by the most precise mechanical engineering.'

The Black Watch, however, was riddled with problems.  So many were returned that the company made a huge loss and would have been bankrupted but for a government subsidy.  However, the Watch is a good early example of Sinclair's interest in aesthetically pleasing electronic products. 

Our Black Watch comes in its original display case.
