Omega, “Olympic” skeleton split-seconds chronograph
The “Olympic” skeleton chronograph was made in small numbers in 1980 ready to celebrate 50 years of Omega’s association with Olympic timekeeping in 1982, since the games of Los Angeles in 1932.
Some sources mention that this model was produced in 63 examples.
This model was available in three different case styles:
·       polished (Ref. BA 143.6716).
·       partially chased (Ref. BA 143.6717).
·       entirely chased (Ref. BA 143.6718).
In the early 1980s these watches were used in Omega advertising with the caption “Omega celebrates 50 years of Olympic timekeeping with a creation symbolizing 134 years in the craft of watchmaking”.
This model is illustrated and described in “Omega - A Journey Through Time”, by Marco Richon, p. 569.
