That link means that over the course of bulova jet star a full wind, the SPB453 averaged at -10.9 s/d, and the SPB451 averaged -7.3 s/d. Given that Seiko says that the 6R55 is accurate to -15 to +25 seconds link a day, both of these watches fall within the stated range of the movement, but both were running on the slow side of zero. I will venture a guess that Seiko regulates these movements in dial-up or down positions, as both were significantly more accurate in those two positions.

And so it proved. At Dubai Watch Week today we get the collection piece in the form of the Big Crown Pointer Date Calibre 403 link a 38mm stainless steel watch link with a deep blue dial a black leather strap and that tell-tale pointer date link function. Its available straight away and costs 3400.
