As I reviewed before the Invicta Grand Diver with black dial, I can be brief here. A bulky, heavy (205g cut) clock, very well made and with features that are rarely for less than 140 found - eg manual winding and seconds Stop the Seiko factory, screw, 30 bar water resistant, engravings, glass bottom, quality clasp and good luminous material. The blue is darker than on the photo, the dial is already more nachtblau. Excellent read, even if you do not have eagle eyes. In direct comparison with the Invicta Pro Diver or even the Gigandet Sea Ground the date magnifier the Grand Diver is much better and shows the date on greater. Who is not afraid some presence on the wrist to show can go wrong when you buy this clock nothing.
