This is a brand new Seiko 5 SNXS79 case and bracelet with a dial and movement swap from a brand new Seiko 5 SNK393.  I used the dial and movement from the SNXS79 on a project watch so what you're looking at is a unique combination not available from Seiko directly.

The movement is a 7S26, a tried and true Seiko movement used in many of their watches.
