This 4823, like its co-habitant the 5855/6 in the Japanese catalogues of 1975, is a very solidly made quartz (your watchmaker will love it!). It is however a thicker watch than its descendant the 5856. To be sure, it has huge presence and its thermo-compensation, due to its relative thickness, is still excellent after all these years.
The gold linen dial work is impeccable, this truly is a high end watch. You noticed of course black striped hand? It gives this watch something extra..... great legibility and some "punch". That punch is also implemented in the mechanics of this watch, it has that special Seiko gimmick of the "jumping seconds hand". This means that it will jump ahead 10 seconds when you pull the crown to adjust the time. It makes time setting so much easier!
In my experience these single quartzes are among the most accurate vintages; the twin quartzes like the 99 series have the specs for sure, but after 40 years or so… build quality and robustness gain the upper hand. The early King Quartzes truly shine!
