At a time when quartz meant LCD displays and designs so far removed from tradition that they were hardly recognizable as wrist watches, Seiko took a step backwards in order to bring watch design forward. The 7A28 was the worlds first analog quartz chronograph, and to say they got it right is an understatement. The 7A28 is a 15 jewel movement devoid of a single piece of plastic. It can be regulated to dial in performance, and was built in a way that allowed for the replacement of worn components. The same can’t be said for most of the quartz movements seen even today. The design allows for three sub registers: one measuring minutes, another is the designated seconds, and lastly a tenth of a second totaler. The center seconds is stationary unless the chronograph is engaged, at which point it measures elapsed seconds for the chronograph. If you are unfamiliar with this movement, we can all but bet that a little research will have you ready to track down your own. In the last couple of years, collectibility for these 7A models has begun to skyrocket, and it’s easy to see why. This example from July of ‘83 is the export version of the “Synchro Timer,” denoted by the 9 at the end of the model number instead of a B. The dial is perfect in a matte black “reverse panda” layout with recessed registers in satin silver. It’s framed by a steeply angled “count up” chapter that flows seamlessly into the bezel. The insert is glossy black with a tachymetric scale in silver and yellow, and this one shows almost no visible wear. The crown sits on the lower left, and is balanced at each corner by pushers that perform the various chronograph functions. The case is unpolished, factory finishes still visible, and it’s completely original aside from a replacement crystal. It comes attached to the original “H- Link” bracelet with  PVD hinges. Post service and with a fresh cell installed, it’s keeping flawless time, and all functions operate correctly. With nice examples being snatched up at record pace, don’t miss your opportunity to add a great 7A28 to your own roster.
