Cate Blanchett wears an unidentified watch

Cate Blanchett wears a gold rectangular watch as Jasmine in Blue Jasmine (2013). The close view shows a gold tank-style case with a white dial and Roman numerals on a brown leather strap, stacked with gold charm bracelets, the faded-luxury look of the once-wealthy Jasmine, very much in the Cartier Tank idiom. I can't read the dial to confirm a maker, so it stays open. If you know it, or want to guess, say so in the comments.
