Robert Duvall wears an unidentified watch

Robert Duvall plays Det. Tom Spellacy in True Confessions (1981), sitting at a counter beside Robert De Niro's priest. His hand rests on the table and the suit cuff pulls back to show a gold dress watch: a squared, cushion-shaped case with a pale silver dial, the sort of 1940s gold piece that fits a period Los Angeles detective. Nothing on the dial names a maker. If you can place it, or want to take a guess, leave a note in the comments.
