1982 JDM Seiko 7A28-7010 “Speedmaster” Quartz Chronograph

1982 JDM Seiko 7A28-7010 “Speedmaster” Quartz Chronograph


Though we typically only offer vintage mechanical watches, it’s hard to ignore the allure of a quartz watch that started a revolution. 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. Though they didn’t officially hit the shelves until 1983, this 7A28-7010 came off the line in October of ‘82, making one of the earliest produced. A JDM model, it carries the “Speedmaster” helmet logo on the original bracelet, and it only gets better from there... The dial is a matte silver with printed registers and text that offer an incredibly clean and legible display. A raised black chapter with luminous hour markers and silver minute hashes sits at its border, and meets the steep bank of the internal tachymetric ring to match the dial. The layout gives this watch great depth and undeniable presence. The angular bezel houses the replacement mineral crystal, and adds nice height to an otherwise thinner profiled tonneau case. The crown sits on the lower left, and is balanced at each corner by pushers that perform the various chronograph functions. Cleaned and lubricated, it’s keeping flawless time, and is sure to be enjoyed wherever it lands.
