I agree that, while Reverso is rightly a classic and a flagship model that JLC should and must cherish, for the reasons you and everyone are mentioning, it is not cannibalized by it the way AP, an exceptional historical brand, has unfortunately been by the RO for a long time now. I also see JLC master control dress watches out there around the office and in pop culture (eg, the Dr Strange movie).
As for Ω, in addition to the Speedmaster, I think of the Olympics, which the brand has timed forever, the Seamaster (including the funky Ploprof) which I also see around the office, in post 90s Bond films, and occasionally on the wrist of the current President. So I don’t see Ω as cannibalized by the Speedy per se. I mean, it went to the moon. A singular historical feat that rightly captivates the world’s imagination. How can Ω not put that front and center? Even so, Ω has made the effort to diversify the model to remind people it’s also a racing chronograph for cars on Earth. Have a great weekend!
