I think you can impose certain conditions to account for various watch styles.

1. Dive watches should use bezel diameter should be used instead of case diameter. Some divers have tapered cases so a 44mm Oris Diver wears like a 40mm due to the 40mm bezel.
2. Cushion cased watches should use vertical case length rather than the formal 4 to 10 measurement for case diameter.
 
For weird shaped watches, I propose that we calculate the area of the watch case and find the circle that has the same area.

A = pi*r^2
A = pi*(d/2)^2
A = pi*d^2/4

d^2 = 4*A/pi
d = sqrt(4*A/pi)

So a 40mm x 40mm square watch would be the equivalent of a circular watch with diameter:

d = sqrt(4*(40*40)/pi)
d = 45mm

I realise that the area of a Panerai watch is very hard to calculate.
