This is the award winning 1 of 200 Seiko SCBS019 "Discus Burger" designed by Tomoko Tamita of Seiko nearly 20 years ago.
The Discus Burger uses a mechanical movement to produce a digital display via rotating discs.
The outer disc displays the hour, middle the minutes and the center displays the seconds.
Given that these nifty models were even cherished and collected by figures such as Max Busser (CEO) of MB&F it is not hard to imagine why these models have become so hard to come across on the grey market.
