Gender: Gents
Brand: Oris
Movement: Oris Automatic Cal 635
Case material:

Stainless Steel


Here we have an Oris BC3 Ref 7500 with a brushed steel case, original rubber strap and day date features.

This watch has a pilots style design with a large crown, bold white arabic numerals and a large steel case.

Despite it being a day date watch the dial maintains it's symmetry due to the two windows being at 6 and 12, with the words 'automatic' and '25 jewels' spaced inside, which is a little different from the usual positioning of this (above 6).

Though the case is quite large at 40mm the brushed steel means it doesn't appear to big, even on a smaler wrist. The exhibition case back shows Oris' signature red rotor inside the polished steel case back edge.

The large crown makes adjustment of the time, day and date very quick and easy.

This comes on it's original rubber strap with a stainless steel deployant clasp.

This watch also comes with it's Oris booklet and box.
