Some collectors don’t think the Grand Seiko Spring Drive is a pure mechanical watch and stay away from it. To me, an engineer by training, the Spring Drive represents a fascinating tour de force in technology and craftsmanship that deserves more appreciation. The Grand Seiko Spring Drive GMT SBGE205 was released in 2017 and I purchased my piece from Chrono24 in 2018. I was very happy to read in the Wall Street Journal one year later a recommendation for the exact same model “for the discreet cubicle drone with tastes beyond Timex” (see a link below).
