Certain, I need a perpetual calendar chronograph – a Patek 5270P, or 5970P is an end-game watch – however can your Patek keep correct to ±5 seconds per 30 days, sync to satellites, time to 1/twentieth of a second, or observe further time zones? No, it could possibly’t. And apart from the 5270T, none are available titanium. With a 100m water resistance and Eco-Drive, that is principally a look ahead to the top of the world. Plus, the blacked-out Duratect DLC case, matching black ceramic bezel and textured black dial simply look cool. Certain, the value is likely to be increased than most Residents I often store for, however I can see the enchantment.
