Diamond watch - Benicio del Toro - Reptile
This seems to be a very cheap (less than $10) round watch offered at American department store Kohls. The watch has a black dial, small fake-diamond on the 12 o'clock position, triangular skeleton hands and the word "DIAMOND" on the bottom half of the dial.
The watch in the screenshot seems to have a steel / silver case, but the watch at Kohls is only offered with a gold case and on eBay we can only find the gold case as well. Either the lighting in the film makes it look silver, or the watch was also available with a silver case.
Also the watch in the movie seems to have a triangular diamond white the Kohls watch has a round diamond.
Get the (gold) watch at Kohls for $7.99.
All details: black sunray dial, diamond accent marker, mineral crystal, black bezel, stainless steel case and caseback. 38-mm diameter case, black faux-leather strap. The watch is powered by a Quartz movement.
This cheap watch is based on the clasic Movado Museum style watch, which also has a round case, clean black dial and a diamond/dot on the 12 o'clock position.
