OR3 Oris TT1 Chronograph. Reference 674.7521.44.64. Watch measures 42mm and is made from steel. Automatic movement base caliber ETA (red rotor). Sapphire crystals on both sides of the case. Waterproof 10ATM or 100 meters. Functions are hours, minutes, sub seconds, chronograph and date. This watch is fitted with the original rubber strap (sized) with a steel folding clasp.

This watch is now rarely offered and is the better version with the good old ETA movement with red rotor that was a signature statement at the time for Oris.
