hi
some info:

Interestingly, in real life, Steve McQueen never really wore the Explorer II [ref. 1655], but rather the Rolex Submariner [ref. 5512], which nonetheless featured a very similar design to the Explorer II [ref. 1655]. The Submariner [ref. 5512], however, was only available exclusively in the UK (produced from 1959 through 1978). It seems reasonable to assume that this McQueen connection (discovered through media photos etc) was what inspired the naming of the later internationally released Explorer II [ref. 1655] as the 'Steve McQueen Rolex.'

so wy the 1655 is called steve mc queen?
for me, there are 2 watchs the heuer and the 5512
