This stunning timepiece is a magnificent example of Seiko's dedication to making precision accessible. The Seiko Lord Matic, reference 5606-7360, is powered by the Caliber 5606, a 23-Jewel automatic movement that is the technical ancestor to the high-beat King Seiko and Grand Seiko models of the 1970s. This alone is a huge selling point: you are getting elite mechanical DNA!

The movement inside boasts premium features that collectors seek: hand-winding and hacking seconds (the second hand stops when setting the time). Aesthetically, the watch is defined by its clean, polished stainless steel case and a gorgeous silver sunburst dial that catches the light beautifully. The Day/Date window is clearly displayed, featuring the desirable bilingual calendar (English and Kanji), a signature of its Japanese Domestic Market (JDM) origin.

The crucial detail your customer needs to know is the renowned 5606 Quick-Set Date mechanism. While revolutionary for its era, the quickset functionality is known to be vulnerable between 9 PM and 4 AM. Therefore, owning a fully functional piece means treating it with the care and respect of a true vintage artifact—a detail that enhances the watch's story and value as a cherished survivor from Seiko’s mechanical Golden Era!
