Cortebert Portez Automatic Watch, Deep Blue, 44mm, NEW
Cortebert Portez Automatic Watch, Deep Blue, 44mm, NEW. This watch has never been worn and is still in its original packaging. All of the tags and plastic are still on the case back, crystal, and band. It has a rotating slide rule bezel which allows for calculations such as multiplication, division, and conversions; the details are laid out in the instruction booklet.
The dial at the 10 o'clock position is what rotates the bezel.
