1969 was one of the most spectacular in Seiko’s storied history. That year, it released the world’s first automatic chronograph, the Calibre 6139 and the V.F.A. (Very Fine Adjusted) movement – which delivered Seiko’s highest yet level of precision for a mechanical movement.
Seiko would release another first upon the world, the first quartz wristwatch - the Seiko Quartz Astron, which went on to change the way the world told time, and severely tested the dominance of the Swiss, bringing high technology within the reach of all.
As the world got accustomed to the novel new Astron technology dominating the market in the late 1960s and early 1970s, Seiko was hard at work on its next innovation to challenge Swiss watch industry dominance, developing the Superior, Grand Quartz, King Quartz, and eventually the matte grey PVD-coated Japanese Domestic Market (Japan-only) 1994 Seiko 7431-6120 watch here with its great sparse matte grey dial, which comes on its original likewise matte grey PVD bracelet and Seiko 7431 instructions manual.
Immediately obvious on the Seiko 7433 here is the vibrant and sparsely-designed matte grey dial, with its red second hand pop of color and similar red chapter ring both providing a great contrast to the watch's otherwise matte grey colors. Add in the Seiko 7431 quartz movement with its hacking feature and screw-down crown, and you have a watch that stands out on the wrist.
Seiko's Danni design house debuted the 7431 movement in 1982, and produced it through the circa late 1990s.
This Seiko 7433 dress watch comes on its original matte grey stainless-steel bracelet, and with nylon strap, rugged travel case, springbar tool, and original Seiko 7433 instructions manual.
