This is a dual-name 1940s Rolex Tudor vintage cocktail watch measuring a dainty 16.5x27mm in a gold-filled case with steel back. This case is all original. These watches were marketed in Canada, with the Tudor movements imported from Switzerland. Then they were dialed and cased here in Canada. The Tudor movement was just cleaned and is accurate. This dial is completely original and dual named, as Rolex often did here for the Canadian market.
