The Vintage Wrist Watch Company has dated this piece to the 1920s.
The watch has a Minerva movement, calibre 9CH, which is working nicely. The movement was in production from 1908, and we would date this particular watch to around 1920.

The watch measures 48mm diameter excluding the winding stem and the loop. The case is nickel and it is in good condition with just general light surface marks. The inside of both of the case backs has large patches of scratching.

The glass lens is in good condition with just a couple of small marks.
The dial is in super condition.
The chronograph feature is started by pressing the button on top of the winding crown, pressing again to stop and then again to re-set to zero. The dial has the 30 minute register at 12 o'clock and constant seconds at 6 o'clock.
The watch comes in a new presentation box.
