The White reminds me of the Deep Blue Cal Diver, although that watch is a Swiss Made ETA 2824 auto
The white model colors do resemble the DB model Pete. These were using the Miyota 9100 movement. Deep blue was one of the first companies to use the Miyota 9100 and 9015 movements followed by Android. Shop NBC sold them for below $300.00 when they premiered on the show.
