In the movie Larry Crowne, Tom Hanks wears a vintage digital Quemex Sport watch. Quemex is a Chinese manufacturer and exporter of watches and clocks.

The watch seen in the film is probably from the 1980s, reads "Quemex" and "Sport" on the case, but the exact model or reference number is unknown yet (post a message if you know the exact model). The watch in the film seems to have a nylon strap.

A similar Quemex watch (see image on the left) is currectly for sale on eBay, but this one doesn't look exactly the same as the one in the movie.
