it's been all 190... The only really great aesthetic feature that the 233 has over the 190 is the DOME sapphire. The date complication is a wash...it's useful, but then I lose the number "3". It would probably be a negative feature if it had the cyclops. ...
The 190 is the only Panerai I have kept on the original strap. It is also such a joy to wind. You will also notice it is almost silent when up against your ear such a smooth movement. Bill
