Prospex Speed-timer Mechanical Chronograph. Designed for those who treat life as the ultimate adventure, the Seiko Prospex line meets every challenge with technological excellence and style. Based on Seiko’s 1972 Speed-timer precision chronograph, nicknamed “Panda” by fans, and developed with added style and function to appeal to young motorsports enthusiasts, this superbly tailored timepiece features a newly designed thinner case curved to seamlessly connecting to the bracelet for enhanced sport elegance and wearing comfort. 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 includes 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 better 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. The silver dial, framed by a tachymeter scale, features blue-gray sub-dials and an orange chronograph hand inspired by the colors of the original model, as well as a date calendar and Lumi-Brite hands and markers. Adding a note of tailored luxury, the multi-row bracelet provides a sleek, comfortable fit. Crafted of stainless steel with a super-hard coating, this extraordinary timepiece also features a dual-curved anti-reflective sapphire crystal, screw-down case-back, and tri-fold push button release clasp. 10 bar, 100M Water Resistant
