Congrats on the BB blue. Looks great on you. Regarding the choice between the WG Daytona and RG GMT, I would go with the WG Daytona but I am biased as I prefer chronographs ππ
If you already have the platona on order, then I would go with the RG GMT. The platona us a veey piece and will most likely get more wrist time than a standard WG Daytona unless you get it with a meteorite dial ππ
