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.
