http://www.watchuwant.com From two of the premier names in luxury come two striking takes on the luxury dive watch concept. The Patek Philippe 5711/1A-011 and Harry Winston Project Z2 Zalium Ocean Diver Chronograph bring high-style and high horology to the high seas. Harry Winston is old-money in the world of gems but a comparative newcomer to the luxury watch scene. But the diamond specialists attacked watchmaking in earnest during the 2000s, and along with the acclaimed OPUS series, the Zalium line of premium timepieces established Harry Winston's credentials in the world of watches. The Z2 stays true to Harry Winston's heritage of high-value materials - rose gold case and white gold pushers, crown - and high end material science: zirconium-based Zalium alloy. The ultra-hard material defies scratches and scuffs that prey on most precious-metal watches. A highly-articulated dial includes exquisite upscale details and clear demarcation of chronograph and time-only functions. Legibility is excellent, and this watch is every inch the functional sports timepiece. Inside the case, a Girard-Perregaux movement maintains the same standards of excellence as the case and dial. A versatile brown natural rubber strap permits surf and turf recreation when the boardroom gives way to board shorts. This Harry Winston Project Z2 Ocean Diver Chronograph is available in outstanding condition with comprehensive factory accessories from watchuwant.com Patek Philippe's Nautilus 5711/1A-011 needs no introduction. A direct descendant of Gerald Genta's 1976 classic, the latest Nautilus reads like a love letter to the company faithful. The striated dial, integrated (and beautifully tapered) bracelet, and flared shoulders immediately evoke four decades of celebrated Nautilus heritage. Inside the case, the latest Patek Philippe Nautilus meets and surpasses the legend of its forebears. An in-house Patek Philippe 324 series movement sits resplendent under a sapphire display caseback. The movement features all of the latest Patek Philippe refinements; maintenance-free ceramic bearings for the winding rotor; Patek's signature Gyromax balance; the Patek Philippe seal. While all Patek Philippe watches built since July of 2009 have foregone the Geneva Hallmark, each watch meets and exceeds that standard. The key: Patek's seal applies to dial, case, bracelet, and movement, not *only* the movement. This Patek Philippe Nautilus 5711/1A-011 is available with all factory boxes, papers, accessories, and the balance of Patek's factory warranty. With two choices like this, you can't lose.
