A big heavy laden ship is far less nimble than a true 'sport' speed boat. 'Small' true independents do have their advantage. Perhaps Patek has grown so large, so self-sucessful, they simply can't afford to truly be daring. They can;t seem to afford to produce a timepiece with a 50, let alone 100-meter waterproof rating. Besides, wasn't the Nautilus to be discontinued??? Back when PP was smaller and more fluid, Dad Stern would have had engineered square movements, of this my entire soul believes to be true (jmho)..
