The Seiko H357 5040 quartz watch, modelnumber WHV005, has both an analog screen and a digital screen (ana-digi watch). The correct movie watch has "alarm chronograph" printed on the dial, a black 'bezel' around the dial with four screws. Note that the watch seen in the film has been slightly altered: the prop makers added a black plastic part on top of the watch, with Seiko logo and vertical 'audio' lines - this part was probably taken from a Seiko A159-5009 (find on eBay). The caseback of the watch features a round speaker through which we can hear Q talking when he messages Bond in the last scene. here
