Introduction
Although Moonphases had occurred in the Omega lineup prior to 1985 the Speedmaster Professional Moonphase 345.0809 was the first to be incorporated into the Speedmaster Professional line.
The watch was issued in November 1985 and in 1986 they introduced an additional redesigned version called the Smoothline Chronograph for the German market.
The smoothline chronograph was cased in titanium with a flat sapphire crystal on a fully integrated bracelet TI345.0810 and also on a bi-metallic titanium and gold combination again an integrated bracelet TA345.0810.
Out of a total of 2000 movements the Smoothlines in Germany had a limited edition release of 400 titanium examples and 300 bi-metallic gold and titanium examples.
Of the 2000 in total there were only 1300 Speedymoons and it is further claimed that 15% were produced as strap-only model predominantly for Mexcio and some for Italy, leaving approximately 1100 in the configuration this site is devoted to.
As far as is known production of all models ceased by January 1989.
