That watch is NOT the Titan Chrono from 1980. The Titan Chrono “01” (not called that but lets use that to reference it… it is Ref. 3700/3702/3704) houses an ETA 7750 just like the original Orfinas. The Chrono 02 (Ref. 3701 also is 7750 based, but housed in Aluminum with a Delrin bracelet. And then yours which is the Titan Chrono 03 (Ref.3732/3743) housed a MecaQuartz movement.
The Chrono 03 is the only smaller one of the 3.
I love them all.
