This WW1 period military issued stop watch would later be called a PATT 3, and will likely have stories to tell if it could.


Military watches didn’t start having dates engraved on the case back until after WW2, but we have found a similar watch to this in the best book for Military watches – Konrad Knirim’s British Military Timepieces. Sadly the watch maker isn’t identified in the book, and we haven’t been able to identify the maker either. According to the book, these were designated to the Artillery.


The artillery would have needed precise timings to work out the range of the missiles they launched, hence the need for a 1/5th second stopwatch – although the gradations on the scale are 1/10th of a second, the beat rate of the watch is 5 time per second so a second can only be split by 5 – no such thing as half beats. This watch in cased in base metal, unpolished and as found which suits the functionality of the piece. The case back has a large Pheon or Broad Arrow on the back, and the dust cover is in place still. The stop watch runs and resets correctly, but does like a full wind before it starts – it is over a hundred years old after all.

This watch will be supplied with a basic presentation box and our Certificate of Authenticity.

From 1st September 2021 we will be planting a tree for every watch we sell, working with the International Tree Foundation (Est 1922) to make this business positive on carbon. By buying anything pre owned you are effectively reusing what already exists, but this takes it further and makes us feel good.
