![]() ![]() Their dials have a sandblast finish which ensures the high level of legibility that is a core characteristic of every Prospex watch. These new solar chronographs are offered in four different dial colours: white, navy, gold and black. The case shape is faithful to the original but its 39mm diameter, the combination of hairline and smooth polishing on the bracelet and the curved sapphire glass bring it right up to date. The new series also includes four new solar chronographs powered by Seiko Calibre V192. Its bevelled hour markers, sharp hour and minute hands with coloured Lumibrite, its chronograph pushers and the markers on the outer dial ring echo the design of the original. The dial design is a subtle nod to Seiko’s and Japan’s first chronograph wristwatch, the Crown Chronograph from 1964. In addition to the limited edition watch, a new creation with the same case and bracelet and also powered by Calibre 8R64 joins the main Seiko Prospex collection. The new Speedtimer is offered as a limited edition of 1,000. If the wearer chooses, the bracelet can be replaced with the black leather strap that is also included and whose stitching is designed to increase the durability of the strap. Its thickness, weight and low centre of gravity ensure stability and a high level of comfort on the wrist. The watch is presented on a stainless steel bracelet that is specially designed and constructed for the series. Thanks to the use of MEMS technology, Caliber 8R46 offers high precision and durability. With the push of the reset button, the hands return back to zero instantly and in perfect synchronization. The escapement is lightweight and strong, thanks to the use of MEMS technology which enhances the stability of the watch’s precision. The vertical clutch and column wheel ensure the precision and durability which are the hallmarks of the 8R Calibre series. It shares the same performance attributes as Calibre 8R48 but incorporates two sub-dials instead of three and has a date window at the six o’clock position. The watch incorporates a new movement from Seiko’s most advanced chronograph 8R series, Calibre 8R46. The large concave pushers ensure the high operability for which the original stopwatch was renowned. The chronograph second hand is gently curved down towards the dial so that the tip of the hand is as close as possible to the dial’s markers and extends to the tachymeter markings at the very edge of the dial, thus ensuring that elapsed time can be read accurately at a glance. ![]() The numerals at each ten-second mark and the markings stand out prominently against the plain white dial and guarantee the same high level of legibility. The limited-edition chronograph’s dial pays homage to the 1/5th second stopwatch from 1964 and every detail of its design inherits the precision and legibility that were crucial to the high performance of the original. A limited-edition chronograph that showcases the very best of Seiko’s chronograph expertise. The new limited edition incorporates several design features from the 1964 stopwatch. It was the world’s first automatic chronograph with a column wheel and vertical clutch, two devices that delivered real improvements in the measurement of elapsed time in a wristwatch and are still a prerequisite in high functionality chronographs. Then, in 1969, Seiko introduced the Seiko Speedtimer with the innovative Caliber 6139. Central to this success was a range of stopwatches that incorporated Seiko‘s innovative “heart-shaped cam” mechanism, a feature that delivered a level of precision once thought unachievable by manual sports timing devices. In the 1960’s, Seiko announced itself on the international sports timing stage with a whole new generation of high-precision equipment that was enthusiastically endorsed by many international sports federations and used to capture elapsed time at many of the world’s leading sports events. The original Seiko Speedtimer released in 1969 A limited-edition watch with a new automatic chronograph movement pays faithful tribute to the design of the 1964 stopwatch, while a second version with the same calibre and a series of four solar chronographs complete the range. Today, a new series of six watches inspired by the Speedtimer and Seiko’s rich and continuing tradition of sports timing join the Prospex collection: Seiko Prospex Speedtimer Chronograph. ![]()
