Prospex Speedtimer Mechanical Chronograph DATSUN 240Z Limited Edition. Seiko Prospex challenges every limit with timepieces created to exceed expectations, engineered with superior style and innovative technology for the sea, sky or land. Driven by a heritage of iconic design, Prospex continues to keep going forward with excellence in precision timekeeping, crafted for the modern world. Commemorating the Seiko-supported “Datsun 240Z” Safari car that won the 6,200km East African Safari Rally in 1971, widely regarded as one of the toughest races in the world, this highly collectible Limited Edition is available only in a controlled production run of 500 pieces. Featuring a font and color motif modeled after the original safari car instruments, the black dial, framed by a tachymeter bezel, prominently displays the Datsun logo as well as the word “Speedtimer,” honoring Seiko’s legacy of sports timing. Providing chronograph measurement of up to 12 hours of elapsed time in 1/8-second increments, the proprietary caliber 8R48 34-jewel automatic movement beats at a frequency of 28,800 vibrations per hour, with a power reserve of approximately 45 hours and manual winding capability. The movement incorporates a column wheel and vertical clutch mechanism allowing for smooth, stutter-free movement of the chronograph hand while providing long-term efficiency, reducing wear and tear and maintaining the power reserve during chronograph operation. For reliable timing, the three-pointed hammer system ensures that all hands return to zero instantly and in perfect synchronization when the re-set pusher is pressed. In stainless steel, with black hard coating for a stealthy look, topped with a dual-curved sapphire crystal and paired with a black leather strap sourced from an LWG certified tannery, this amazing creation includes a date calendar, LumiBrite hands and markers, a tri-fold push button release clasp, and a secure screwdown caseback engraved with the Datsun logo and the Limited Edition production number. Presented in a Limited Edition collector’s box. 10 bar, 100M Water Resistant
