Possible Bulova Pocket Watch from 1925
This one has me stumped on authenticity and date. The white gold plated case is made by Monarch (BWC Co) and I'm not sure if the serial number means anything in regards to the date of the watch. The movement is a Swiss 17A, 17 jewels, circle date stamp for 1925, serial number 55492. The watch case is similar to this one (https://mybulova.com/watches/1926-470-9143?page=0), though with a different dial. The dial on this is in very nice condition.
I am unable to identify a model number or name, possibly like the above linked 470 with plain dial.
Some notes on the movement; all of the bridges have the last 3 numbers stamped on their undersides, 492. The case bezel ring and main case both have 77988 (Roman numeral format on the bezel ring).
Keen eyes may note that the escape wheel is missing, as I am looking for a replacement to get this one running again.
