Is anyone familiar with the history of the 'Crusader' watch company? From what limited information I have been able to find they seem to have made watches (wrist and travel/pocket watches) between WWI and the sometime shortly after WWII, primarily for the UK market. I am speculating they were a contemporary of Rolex, having the case manufactured in England (by Adie Brothers Ltd?) with the movement and dial purchased from a Swiss supplier. The movements typically had Crusader etched into the ratchet gear with one or more stars.
The watch in question is hallmark stamped at 1937 from the Birmingham Assay Office. The dial is labeled Hamilton & Co LTD, Calcutta (no relation to the American watch brand, rather a famous Jeweler in India). Again based on limited research I am speculating Hamilton's UK purchasing agent acquired the watch from Crusader with a custom labeled dial for export to India. I have found a few similar examples of the same watch with the Crusader name in the top rectangular area and no text on the dial face.
Regarding the image of the movement, it is after a recent cleaning by the good folks at RGM Watch Co. of Lancaster P.A. I think they did a great job.
