Notes

Ref. ST 188.0002 Launched in 1973, this was the first electronic Speedmaster, available with gray or blue dial, or a gold-plated version (Ref. MD 188.0002). While the 5 ?Speedsonic? references are sometimes considered a separate line, or part of the Seamaster line, in all the literature they are clearly part of the ?Speedmaster? line.
