Oris TT3 Chronograph Black
This new version of the Oris TT3 Chronograph comes dressed in a large (44.50mm in diameter) specially coated black titanium case.
Also black are the tachymeter bezel, the crown, the pushers, and the flexible lugs. Even the carbon dial is black, making the displays of current and elapsed time with their luminous inlay even easier to read under the sapphire crystal.
Equipped with the 25 jewel Oris Calibre 674 (base ETA 7750), this automatic watch has a power reserve of 48 hours. In addition to chronograph function, its displays the small seconds at 9 o’clock and the date at 6 o’clock.
The signature red rotor of the Oris High-Mech chronograph movement is visible through the transparent mineral glass window in the case back.
The Oris TT3 Chronograph Black is waterproof to 100 metres/10 bars, and the crowns are protected by the Quick Lock System. The black rubber strap completes the perfect look for this sporty chronograph.
