The Blancpain x Swatch Scuba Fifty Fathoms lineup just got a little bigger and a bit more verdant with the announcement that, starting on June 7, you can now head to a Swatch store to pick up the brand’s new “Green Abyss” take on their $400 Bioceramic dive watch collab.

The rule set forth by Jean-Claude Biver at the relaunch of the Blancpain brand was that they had never used a quartz movement and never would in the future, and that still stands, with a Swatch-made SISTEM51 automatic-winding mechanical movement inside the 42.3mm by 14.4mm forest green case. That color nicely complements the vintage-hued cream Super-LumiNova on the hands and hour markers. That dive bezel is unidirectional, made of green Bioceramic, and has a deep black resin insert with Super-LumiNova inside. The watch features 91m of water resistance (Fifty Fathoms of water resistance, in fact).
