Because from one perspective you might look at Parmigiani's
link latest release and decide it is functionally neither a GMT nor a rattrapante. And if you were to be extremely pedantic about horological terminology
link I might even agree with you. But I prefer to focus on what the watch
link is instead of gatekeeping what it isn't and what the Parmigiani Tonda PF GMT Rattrapante is is one of the most interesting and understated dual-time watches in years.
