A lot has been written this year about the 60th anniversary of Grand Seiko, but 2020 is also the 160th anniversary of the birth of Seiko founder Kintaro Hattori, who established the company in 1881 when he was just 21.

To mark the anniversary of Mr Hattori’s birth and 140 years since Seiko was created, Grand Seiko’s Micro Artist Studio has designed two limited editions that will go on sale early next year.

Both watches are said to exemplify Mr Hattori’s dedication to the mastery of every aspect of the watchmaker’s art.

Grand Seiko has added the Kintaro Hattori 160th Anniversary Limited Edition SBGZ005 to its Masterpiece Collection using the hand-wound Spring Drive Caliber 9R02 with an 84 hour power reserve and accuracy of ± 1 second per day.

The limited edition of 50 pieces comes in a slim 37.5mm platinum case with an exhibition case back and will have a recommended price of £95,740 when it goes on sale in January.

Grand Seiko’s Micro Artist Studio chose to recreate the brand’s first rose gold watch for its Seiko 140th Anniversary Limited Edition SBGW260.

It uses the hand-wound Caliber 9S64, which is accurate to +5 to -3 seconds per day and has 72 hours of power reserve, housd in a 38mm 18ct rose gold case.

There will be 350 made, which go on sale in March next year for £26,500.
