Since the GM-B2100D-1AER Steel Casioak deal was so popular I thought this was worth posting.

The GST-B500D-1AER in this deal loses the Casioak design but is arguably easier to read (thanks to lighter hands and hour markers) and still has Tough Solar and Bluetooth connectivity (with the same App).
Edit: Also would like to add if the Casio Watches App time sync works anything like the G-shock Move App for my current watch, it will work best with App location permissions on the phone set to "always". So the watch can fetch the geo location time data at any time during it's regular cycle.
This GST-B500D is half the price of the GM-B2100 Casioak so has Carbon Core (resin) case with Steel bezel and Steel band. GM-B2100 Casioak with it's higher price adds a Steel case with a screw lock back.
The GST also has the same digital LCD and LED location as the Casioak, so no trouble with visibility of LCD in the dark. Although the GST only has lume on the hands, while the GM-B2100 adds lume on the hour markers.
Most of the specs are identical with the GST being 22g lighter on the wrist and a little more square in dimensions, meaning lug to lug should be less and it should fit better on smaller wrists.
GST-B500D dimensions are 46.6 × 48.9 × 12.8 mm (L× W× H).
So the choice is yours, pay half the amount for Carbon Core or save up $600 for GM-B2100 Casioak.
