It might seem contradictory to give a watch like Panerai’s Submersible a case made of precious metal. Perhaps it’s got to do with how overtly sporty and robust the timepiece looks. Yet, gilding this new model in Goldtech—a Panerai innovation—doesn’t diminish the ruggedness of the Submersible in the least. In fact, its sporty appeal feels suitably elevated via the black-and-gold pairing of the alloy with yet another of the brand’s proprietary material, Carbotech—an effect that’s further heightened by the stylishly subdued matte finishing.
