The various functions are driven by the calibre PF441, an automatic movement with chronometer certification link by the COSC. With the help of a double barrel, it link supplies the watch with link up to 55 hours of power reserve.

Early on DiCaprio wears a Seiko which I hadnt noticed until I talked to the films prop master Robert R. Griffon Jr. It looks to be a Seiko Solar on a stretch band with a blue or black dial. You can see the day-date complication during link the famed lunch scene with McConaughey who wears the watch link of the '80s A two-tone Rolex Datejust or a very convincing replica. Interestingly in this scene DiCaprio link wears his watch on his right wrist which is the only time in the film he does so.
