A Superrare Omega Speedmaster BETA light Prototype for NASA

All stainless steel lyre lug case, push-in, brushed steel caseback with seahorse engraving, larger pushers
Omega quartz movement, calibre 1621, 0 jewels

Overall, the watch remains in mint condition. The LCD display works well, showing no loss of pixel. The stainless steel case remains unpolished, showing a brushed finish on the sides, and remains of violet protective foil on the caseback. The watch is in good running condition with recently renewed batteries.
This is a highly rare example. 1 of only 20 prototypes produced by Omega with BETA light (2 tritium stripes permanently illuminate the dial in the dark instead of a light bulb like in the civilian example) for NASA in 1978. 12 of them were numbered and sent into NATO. A very rare chance to acquire a very rare watch!
