First introduced in 1969, the Speedtimer was the world’s first automatic chronograph with a vertical clutch and column wheel, establishing a new level of accuracy for high-performance stopwatches. This latest Speedtimer features a colour scheme inspired by the neo-classic cars of the 1970s, known as “young-timers,” while its flowing case shape, first featured in the famous 1972 Seiko “Panda,” is finished with a super-hard coating.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eUnder curved sapphire glass, the petrol blue dial is encircled by a countdown timer, with a strong Lumibrite coating on the inner-ring reference triangle for enhanced clarity.

It is paired with a sustainable LWG-approved leather strap featuring an embossed pattern inspired by vintage car interiors, combining the character of classic automotive design with the practical qualities of the Speedtimer.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eThe HBC004J1 is powered by the in-house built 6R55 automatic calibre, offering accuracy of -15\/+25 seconds per day, advanced shock protection and an impressive 72-hour (three-day) power reserve.
