Grand Seiko SBGX103 movement

Something different for #macromonday as I take the caseback off my daily beater SBGX103 to share am image of the amazing 9F62A movement. The SBGX103 was released as a limited edition of 2000 pieces in 2013 to celebrate the 20th anniversary of the 9F movement.
Such beautiful finishing on a quartz movement, and they hide it away!
As if the thermocompensated calibre accuracy of +/- 10 seconds per year (yes, per YEAR) wasn’t already enough, for the SBGX103 Grand Seiko went the extra mile and these watches are regulated to an incredible +/- 5 seconds per year. And – crazy wrist-mounted atomic clocks excepted – I believe that makes them the most accurate self-contained (i.e. not reliant on external time signals) watches in the world.

With a little over 50 watches now in the vintage Grand Seiko collection, a handful have somehow slipped through the net and not been shot for months! In fact, I don’t think I’ve photographed this 4520-8000 in almost a year.
A fabulous model from March 1971, I’m fortunate enough to have an example in pretty much NOS condition, and as a full set with box and papers.
Have a great weekend everyone!

I’ve mentioned previously that I believe the 6155 and 6156 movement “Specials” are amongst the current best buys in the vintage Grand Seiko range. At the time when they were new, only the VFA’s were regulated more accurately. The “Specials” being regulated to +/- 3 seconds per day.
Interestingly enough, whilst there is just a single model of the date-only 6155, there are no fewer than 8 different models using the day-date 6156 calibre, one of which is the rarely seen 6156-8020 version pictured here, which is the only “Special” to be cased in Cap Gold.
