Just as the hammerhead evolved the keenest sensory accuracy of all sharks, so too is Ulysse Nardin evolving the highest accuracy and efficiency. This is evident in their latest evolution the Diver Chronograph Hammerhead Shark. This rugged 44mm watch made of 18K rose gold is limited to 99 pieces, and boasts an impressive array of features, including 300 m of water resistance. The unidirectional rotating bezel provides much needed information for the oceanic explorer and surrounds a dial packed with useful complications. The UN-150 caliber provides central hours and minutes as well as a central seconds hand that works with the chronograph. Added to this are the small seconds subdial at 9 o’clock 30 minutes subdial at 3 o’clock, 12-hour subdial at 6 o’clock and date at 6 o’clock. Within the 30 minutes subdial there is a lone red shark, emphasizing that this is a limited edition, not a timepiece that comes along every day. The regal blue of the dial fascinates with the outlines of hammer head sharks as well as the proud name of Ulysse Nardin below the 12 o'clock mark. The transparent sapphire crystal case-back provides an intriguing view of an azure rotor with shark detail. Finally, this impressive timepiece is fastened to the wrist by a rubber strap with 18K rose gold elements and a deployment buckle.
