Ever accidentally taken your watch into the sauna? The end result of doing so may be a relaxed body, but that relaxation will almost certainly be undone when you realize you now have a completely cooked watch. Casio, however, has a fix and in fact, is crowdfunding a watch thats not only sauna-approved, but specifically built for it.The watch is currently dubbed the Casio CPP-002, and is purpose-built with enough durability to survive use in ultra-hot and ultra-humid environments. The watch is being crowdfunded on Japanese platform Makuake, and the campaign is set to last three months, so it could be a while before youre able to get your hands on one.There are three models of the CPP-002. Theres the black, white, and orange CPP-002-OR; the all-black CPP-002-BK; and the black and blue CPP-002-BU, which was designed in collaboration with sauna platform Sauna Ikitai.Color-scheme aside, the watch has a 35.44mm body, with an analog watch face. Not only that, but it has a 12-minute counter that sauna-goers can use to time their sessions, and an expandable band thats perfect for gym locker keys.Of course, theres more to durability than just the outer body. The watch has a special heat-resistant battery that Casio says should last roughly five years. And, the device has a 5 ATM rating, or the ability to be used in water as deep as 50 meters.Given the fact that the watch is still undergoing its months-long crowdfunding campaign, its currently unclear if itll get a full production run. That said, during the campaign it runs between 10,000 11,000, or around $60 to $70. We certainly hope it gets a wider launch, even if it does end up being something you only use at the sauna.
