Seiko Sampachi: Innovative Day-Date
Seiko Important V.F.A. Sampachi-Quartz, Hammered & Heavy

- Day-Date
- Time (Hour, Minute, Central Second)
三八 (さんぱち, Sampachi) means "three and eight" and it is this cal38 that is the core of this important & beautiful & technologically outstanding watch -- a horological milestone in many ways: Very Fine Adjusted (V.F.A.) Sampachi-Quartz. A well-thought and -manufactured watch-movement that has an outstanding position in horology; on top of this horological & technological achievement is the mesmerizing washi-paper dial with 12 applied hour-indexes and the applied & floating SEIKO- & QUARTZ-logo; encased in a heavy and close-to-perfect watch-case. Something that would today find its position in the Micro Artist Studio-made Credor-line or in Patek Philippes "Rare Handcrafts" ("Métiers d’Art"), because it is exactly that: the finest art of manu-facture (ie. hand-made).
What we see here is something so special and outstanding -- a horological very important watch and at the same time something of probably perfect appearance: the worlds first quartz with (analog) temperature-compensation -- the first car with a turbo-charger: something that changed watches (precision) and cars (power & efficiency) forever -- in perfect design and execution.
NB: The modern and exalted design finds a reminiscence in the Seiko Power Design Project 2026 as shown in the fourth photo. The fifth is the comparison of this watch vs the new platinum SBGZ011.
The first temperature-compensating quartzwatch and thus a horological milestone; but as well a testament to Japanese art & design. Same as the Porsche 930, which was the first and innovative Turbo-charged road-car and changed output-efficiency of a car-engine, the Seiko Sampachi V.F.A. cal38 was the first temperature-compensated electronic watch and changed the output-efficiency of a quartz-watch (precision) significantly. Both appeared in 1973 (1974 for the Porsche 930) and both shared the wide-body design and the manufactured (ie. completely handmade) hammered sides. See our article: "Turbo & Temp: Porsche 930 & Seiko Sampachi".
The very rare and special whitegold variant with the early (just made in 1973) hammered dial: this is one of the rarest Seiko V.F.A. and it is probably the technologically most interesting because of its innovative movement and the amazing monocoque-case.
Additional to that it is the first 18K-whitegold Seiko ever.
