I came across this post and noticed the pictures are now missing. They appear to have been reproduced here: watchesinmovies.info/tv/prisoner-the-1967-1968/
To me, the watch Patrick McGoohan wears in the episode calls "Arrival" and uses as an "electropass" looks like a modified Hamilton Super Compressor (the bezel is blacked out and the 12 o'clock marker replaced by a bright dot).
