Introducing the stunning Seiko 5 Sports Speedtimer Rally Meter 7015-7010, also known as the "Blue Rally" or 「青ラリー」in Japan.
 
While many collectors tend to focus on Seiko's Suwa-produced 613X chronographs, it's worth noting that Seiko's Daini division also developed their own impressive 701X calibers.
 
Daini's chronographs may lack the minute and hour registers typically found in other models, but they compensate for it with unique features exclusive to their designs. The Rally Meter 7015-7010 from April 1973 stands out as one of the most visually appealing chronographs in the Speedtimer lineup. Its conical case widens at the bottom and slopes sharply towards the bezel. The well-proportioned lugs allow for a seamless integration with the original triple-hinged XLA071 "5 Sports" bracelet, commonly seen in 6139 models. Interestingly, this is the only Daini chronograph that shares the same XLA071 bracelet with Suwa's 6139 series.
 
Taking a closer look at the dial, the matte black bezel insert features a pristine silver and yellow tachymetric scale. The dial itself exhibits a captivating layered effect, with the lower portion displaying a charcoal sunburst finish adorned with applied markers. This lower section is framed by a metallic silver upper ring trimmed in black and electric blue. Adding to its functionality, a glossy black rotating inner bezel completes the slide rule function outlined on the dial. The hour and minute hands are elegantly polished batons with luminescent material, beautifully balanced by a vibrant orange sweep hand.
 
Highly sought-after in Japan, this model ranks among the rarest variations within the Rally Meter collection.
