012-68SP, dates to approximately 1968. It is constructed from stainless steel and features a notable 'racing dial', characterized by its black surface accented with distinctive red baton indexes and matching red hour and minute hands.
The watch is powered by the manual-wound Caliber 321 movement, comprising 17 jewels. The dial layout includes three subsidiary registers for running seconds, a 30-minute chronograph counter, and a 12-hour chronograph counter, alongside a central white chronograph seconds hand. The 42mm stainless steel case includes a screw-down reverse stamped with the signature Speedmaster motif and is fitted with a tachymeter bezel featuring the 'Dot Over Ninety' (DON) configuration.
The watch is presented on a stainless steel Omega Ref. 1125 bracelet with 533 endlinks and a folding clasp. The movement, dial, and case are all signed by Omega. This specimen is part of a limited known group of 'Professional' examples featuring the racing dial configuration, historically associated with UK distribution.
