1983 Seiko “Speedmaster” Chronograph 7A28-7040

While we usually specialize in vintage mechanical watches, the allure of a quartz watch that sparked a revolution is undeniable. In an era when quartz technology was synonymous with LCD displays and futuristic designs, Seiko took a step back to move watch design forward. Launched in early 1983, the 7A28 became the world's first analog quartz movement with an integrated chronograph function.

The 7A28 is a 15 jewel movement devoid of a single piece of plastic. It was built in a way that allowed for the replacement of worn components which can’t be said for most of the quartz movements seen even today.

The 7040 has a sixty-click bi-directional zero to sixty bezel with H/M and chrono sweep seconds on the centre , with running seconds on the 6 subdial, 1/20th second counter on the 3 subdial, and elapsed minutes on the 9. The layout gives this watch great depth and undeniable presence with obvious design ‘inspiration’ from the Omega Speedmaster.

As a JDM model, it carries the “Speedmaster” helmet logo on the original bracelet,  Note that even with the extender the bracelet will only fit a wrist up to 7" (17.7cm). 

The watch is 40mm wide excluding crown & pushers, 43mm from lug to lug with a thickness of only 11mm.

All functions work correctly, no stuck or 'sticky' hands.  The bezel was replaced with a NOS one, so is in perfect condition.
