The Ocean Racer was one of a kind. However, it was released some time ago. In the past year or so the entire Yacht Club series had their dial-sized reduced from 45+ mm to 43+mm. This is in-line with IWC's recent decision to going back to smaller dial-size.
Although I adore the Yacht Club series a lot, I do think it overlaps too much with its Portguieser Classic Chrono series of watches. Noticing that IWC has released a few newer models of the Classic Chrono this year, I am not surprised (but obviously am a little disappointed) to hear that they may no longer produce the Yacht Club line of watches. A sporty version of Portguiesers, what a novel concept! Alas, Portuguiesers are Portuguiesers. They are meant to be the more dressier line of watches for IWC. Who knows, perhaps it is time for the Portugieser line to return to its roots, leaving Aquatimer to be the sporty line of watches for IWC? Just a thought...
