There are 2 Bulova Supercompressor.
A normal size (36mm), and a XL (42mm)
While the 'standard' can be found from times to times:
the XL is very very hard to come by
(Here the XL in front of the regular, hiding it almost completely due to size)
(Same shot, watches in reverse order)
(And the 2 with 2 XL cousins)
