The alpha handset does not lie – this chronograph was manufactured in the mid-1950s, and remains in outstanding condition, with the radium developing a gorgeous patina. I especially like the sobriety of the dial, which only bears the Omega line, and not the Seamaster designation. The dial also has a discreet outer tachymeter scale – a reminder of the tachymeter bezel of the later Speedmaster, with which this chronograph shares the highly regarded caliber 321. The case is still sharp, and the case back is engraved, which to me always adds a bit of charm to a vintage piece.
