After over 50 days of wearing my SBDX001 Marinemaster I decided that I would wear what could possibly be a GADA selection, the SBGX259 Polar White dial Grand Seiko 9F Quartz that I have owned for a year now. At 37mm it is the antithesis of the MM300, I'm fortunate to also own the OEM crocodile strap and GS deployant clasp which dresses this piece up quite nicely. Yes, the ticking seconds hand is not for those purists who enjoy the smooth sweep of a mechanical but I can certainly live with it's amazing accuracy and precision. I imagine it will get some binge wear on Summer evenings as a reliable companion piece to the Marinemaster.
