The Vintage Wrist Watch Company has dated this piece to the 1910s.
The watch has a high grade movement with 23 jewels, five adjustments, which is working nicely. There is a patent micro regulator, Ohlson 1908.
The high specifications of the movement tell us that this is a railroad grade piece.

The great North American railroad watch became an institution after a fatal crash in 1891, which was caused in part by the stopping and then restarting of the engineer's watch, which caused it to be four minutes slow. In the early days of railroading, when trains ran by strict time and timetable rules, that four minutes proved to be fatal. As a result, in 1893, the General Railroad Timepiece Standards were adopted, which mandated high grade specifications including a minimum of 17 jewels in the movement, five adjustments and micro-metric regulation.

While this particular watch would not have been used on the railways as it is not lever set, the specification was still at the required high levels and these high grade watches were purchased by other professionals and also civilians.

The movement is protected by an inner hinged cover.
The watch measures 50mm diameter excluding the winding stem and the loop. The case is the gold filled Moon model from the Dennison Watch Case Company, the company supplied the majority of cases to Waltham UK. The case is in very nice condition, just one pin prick “ding” to the front.

The small central lens is surrounded by enamel filled Roman numerals.
The front cover is opened by pressing the winding crown in.
Inside, there is an acrylic lens which is in lovely condition.
The signed triple sunk dial has a short hairline by number 1 and another short hairline just underneath the subsidiary seconds dial. It is good to see the special half hunter hour hand which means that the time can be read when the front cover is closed.
The watch comes in a new presentation box.
