Subcrew x G-Shock DW-6900SCR-3DR Shark Marine Collaboration on 50Gs

This limited edition was designed by the Hong Kong-based brand in 2010. A super-limited batch of 100 pieces came out first and included a shark-shaped submarine toy. Those were each numbered on the case back. And then Casio did a second release of these without the toy, where there was at least 1,000 pieces produced. These watches have a fun design and the Shark marine toy really sets it apart from other collaborations.
