The watch
Seiko Lord Quartz from 1979 in very good, unpolished condition. The deep brown sunburst dial is very impressive yet understated. The case, crystal, and bracelet show some signs of wear but remain in very good condition overall, offering great value. You can choose to display the day in either Japanese Kanji or English.
The quartz crisis
The "quartz crisis" was a major turning point in the watch industry during the 1970s and 1980s, driven by the rise of quartz technology. Companies like Seiko led the way, offering watches that were more accurate, more affordable, and easier to maintain than traditional mechanical models.
With the launch of the first quartz wristwatch, the Astron, in 1969, Seiko showed the world what quartz could achieve. Swiss watchmakers, known for their mechanical craftsmanship, were slow to react and lost much of their market share. The crisis forced the Swiss industry to restructure and helped shape a future where traditional watchmaking and modern quartz innovation could exist side by side.
