This is a large steel 49.5mm. Rolex pocket watch which were issued to the British service in WW2 circa 1938. The stunning black original dial and cathedral hands look amazing. The manual winding Rolex (Cortebert 540 caliber) movement was just cleaned and is accurate. These movements were very robust and reliable. At some time either the dial or case back was changed during a service so the case back numbers don’t match the dial number. They are exact correct and original Rolex parts; only the number not matched-no big deal and was often the case during war time. The deep black original glossy dial will really catch your eye with its stylized Arabic numerals. The watch came from an estate and has its original leather lanyard still attached. This dial looks MUCH better in person than my photos. Usually these Rolex watches were worn by officers. You can imagine the places and WW2 situations this vintage Rolex pocket watch has been through!
