The Hercules HP Black Dial Tantalum pairs the dense, greyish tantalum case with a black dial, a darker and more discreet take on the HP than the pastel Ice dials. It shares the 40 mm diameter, 9.4 mm thickness, 46 mm lug-to-lug, sapphire crystals and 100 m water resistance of the rest of the range, with the choice of the 120-hour double-barrel hand-wound movement or the micro-rotor automatic, both Timelab chronometer certified.

Hercules treats the black dial as a dial option on its tantalum models, so pricing follows the tantalum range (about €11,995 to €15,495 depending on finish), and I could not find independent reviews of this specific dial. Reception of the tantalum HP overall is positive for its colour, weight and comfort at 40 mm, with reservations about price. It is available made to order.
