Seiko 5 Sports Heritage Design Recreation Limited Edition. Released in 1968, the first Series of Seiko 5 Sports, now iconic to Seiko fans, is reimagined in a highly collectible Limited Edition, replicating the size and form of the original with updated specifications. Available only in a controlled production run of 9,999, with the serial number engraved on each vintage-style caseback, this creation follows the design cues of the original with a bi-directional rotating bezel, box-shaped crystal, and original Seiko 5 emblem logo. The black dial features a dual color day/date calendar, and LumiBrite hands and markers with a vintage flair. Upgraded with Seiko's 4R caliber that you control with every motion, the 24-jewel movement beats at a frequency of 21,600 vibrations per hour, with a power reserve of approximately 41 hours and manual winding capability.
