Looks like this is a new one for the database. 10K white gold plate case with stainless back. Single diamond at 12 position. This is a real slim one and the faceted crystal gives the appearance that the bezel is wider than it is. Replacement band installed by me.

Face has some crazing but it's only really apparent under magnification. Original crystal was badly scratched, but with patience and about 1 hr of vigorous hand polishing with a cotton ball and crystal polishing compound, it came back nicely. Runs and keeps perfect time. Face appears darker around the edges due to shadowing. It's a consistent silver color in person.
