Yesterday I was at the place of Gerald and he asked to me whether Speedmasters were always stop watches. I should not have thought long and known as that I cannot remember to see them. Then it showed me this booklet of Omega of 1991 with Speedmaster on the cover what was not a stop watch. The referencenumber is certainly Speedmaster, since it is in the 3000 series. The case-form showed some similairities as well (note the outside of the hooks). But that it.

No Speedmaster on the dial as well, but me was known as only the caseback had the engraved Speedmaster.
