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 few years, collectibility for these 7A models has begun to skyrocket, and especially so for hard to find variants like this titanium Sports 100 from May of 1983. It was available in two color ways, an all PVD black with gold trim, and this titanium gray with a black dial and white trim. Unlike stainless steel alloys, titanium is a pure “specialty” metal. It’s incredibly resistant to corrosion, and exhibits triple the strength and durability of most steel alloys at only 40% of the weight. Beyond the structural benefits, it’s also one of our favorite layouts for the 7A28. The dial is a spotless matte black with crisp white hands and markers, and a single spot of color comes from the bright yellow chronograph seconds hand. A steeply angled tachymetric chapter adds great depth, even in contrast to the low profile of the integrated bezel. Hooded lugs and flared case edges make for a familiar, yet still unique architecture. It’s unpolished and completely original aside from a replacement crystal, and post service with a fresh battery, it’s keeping perfect time and all chronograph functions are operating correctly. It comes attached to the original titanium and stainless steel “Bar” link bracelet that will comfortably fit up to 7.25”. For larger wrists, we can install a clasp extension by request. A hard to find highlight in the 7A28 line up, this one is sure to be a fast favorite on any roster.
