Introducing the last great modern complication, the Speedmaster 125 was the first automatic chronometer chronograph and was the second ever limited edition from Omega. It was only produced in 1973. (Arguably the FPJ resonance is also a great modern complication)
@Darlinboy 's beautiful FS Bulova (woulda snatched it in a NY minute!) inspired me to get out my own 'Alarm Watch':
Not sure that end links would fit this band. I got the band from a jeweler in 2001, it's actually the wrong size, they had to grind it down to fit. I didn't know any better back then.
