Grand Seiko Heritage Hi Beat 40 mm Shubun Ref. SBGH273G

• Description

  Grand Seiko Heritage Hi Beat 40 mm Shubun

  This is a modern re-interpretation of the celebrated 62GS from 1967. The 62GS was not only Grand Seiko’s first watch with an automatic movement, but it was also, along with the 44GS released the same year, the watch that first expressed the design grammar, the Grand Seiko Style, that still shapes all Grand Seiko designs today. Like its predecessor, this modern re-interpretation has the characteristic sharp edges and perfect distortion-free surfaces that only Zaratsu polishing can create and a wide dial opening which was achieved thanks to a bezel-free construction.
  
  The dial is inspired by the clear night skies that Japan enjoys at Shūbun, the sixteenth of the twenty-four sekki or seasons which falls around the time of the autumn equinox. The gold toned Grand Seiko lettering and seconds hand stand out in sharp relief against the deep blue dial, echoing the way that moon and stars illuminate the sky at night.
  
  The watch is powered by the hi-beat automatic caliber 9S85 and is hand assembled by the skilled craftsmen and women of the Grand Seiko Studio Shizukuishi.
