Gents, would like to hear your thoughts on the your favorite of the following 5 watches:
- Blancpain Fifty Fathoms

- Panerai 233

- IWC Portuguese (5001-09, black dial)

- IWC Big Pilot (5009, not 5002/5004)

- AP Royal Oak (15400, black)

Putting aside considerations of price or versatility, which is the most beautiful? (Am leaning a couple ways, but interested in hearing views of SF)
