Grand Seiko 4522-8010

$7,500

With its stunningly textured solid 18K gold case, the 4522-8010 is a highly sought after and collectible vintage Grand Seiko reference.

The case is actually the same as that to be found on the legendary 4520-8020 Astronomical Observatory Chronometer (“AOC”), but there could be no confusing the two watches even from a distant cursory glance because their dials are so different. The reference was introduced in 1970 at a price of 145,000 Yen.

The example presented here is in excellent condition – the case shows little to no signs of polishing, with the case back retaining its subtle circular brushed finish. The linen texture to the front side of the case remains strong and well defined, with the factory polished surfaces of the case showing only minor signs of wear.

There are a couple of minor stains on the dial that can be clearly seen in the accompanying photos.

On a timegrapher in the dial-up position, the watch is running at around +2 seconds per day.

Description

The 45GS series was the second, and final, series to be manufactured by the Daini Seikosha company.

Unlike the contemporary 61GS series from Suwa Seikosha, the model structure and numbering methodology for the 45GS series is both clear and consistent. A total of 19 distinct models were produced, with 18 of them being available for general public sale.

There were just three calibres used for the 45GS series – the 4520A (no complication), the 4522A (with date complication), and the legendary 4580 VFA.

Both 4520A and 4522A calibres were offered in four case variations. Versions of all case designs can be found for sale on this website.

  • -7000 cases are highly angular, with sharp well defined contours, edges and corners. Cases were available in both steel and cap gold variants, with the steel versions being available with two different dial finishes – off-white linen textured, and a dark blue matte. The dark blue is sometimes misinterpreted as being black in colour, and – somewhat confusingly – after-market re-finished dials are available in black. (Total of 6 legitimate models across the two calibres.)
  • -7010 cases are oval shaped, with brush metal finish. There are two dial variants for these models – one with 36,000 on the dial, and one without (Total of 4 models – two for each calibre, with and without the 36,000 designation on the dial)
  • -8000 cases adhere closely to the “Grammar of Design”, and come in both steel and cap gold. (Total of 4 models, two for each calibre)
  • -8010 cases are distinguished by being made in solid 18K gold, and finished with a linen-like texture. (Total of 2 models, one for each calibre)

In addition to the above sixteen models, there was also a version of the 4522-8000 in steel that was made for the Toshiba corporation as a commemorative watch given to employees who celebrated 25 years employment with the company.

Finally, there are two VFA models utilising the 4580 calibre. These models can undoubtedly be considered the absolute pinnacle of the entire vintage Grand Seiko era, and either of them would qualify without peer as the ultimate “grail” piece in any vintage Grand Seiko collection – not just because of their rarity, but also because the represent the ultimate achievement of what Grand Seiko was all about – creating quite simply the best watch on the planet.
