I haven't been able to find this model in any of the 1952 adverts here or on other sites. I did find a picture of the same watch model on Pinterest also listed as 1952 so I'm initially inclined to believe the date code on the back.
Has a similar case to the Roderick and Trident models which appear a few years later. Suspect this version might go by another name with the variation in the dial design.
As indicated on the Trident link above it may be a 'Hartley' which has a similar (if not the same) crystal of that used by both the Roderick and Trident.
I like this one, it's in very nice condition. I agree that we don't have a positive ID on this case/dial combination. I think the case is Trident based on the advert referenced in the link above. I was tentative on that ID and would be the same here.
