let's agree to disagree. IWC is not steep in history like OP but IWC has been evolving and heading in the right direction. I'm particularly intrigued by the Pilots line, particularly the BP Top Gun Miramar Chrono and the Perpetual Calendar. Similar to OP, IWC has been using different case material and moved toward all in-house movements.
Additionally, although both OP and IWC are both Richemont owned, IWC (so does JLC) get to new models introduced at SIHH to market a lot sooner too.
