Sony has gone official with the Xperia ZR, a new high-featured Android smartphone that takes the Xperia Z's waterproofing credentials to even greater depths.
Its IP55 and IP58 compliance (versus the Xperia Z's IP55/57) means the Xperia ZR is capable of being submerged in up to 1.5m of fresh water, rather than the Xperia Z's 1m. Yes, really.
Whether that's worth no longer being able to say the flagship Xperia Z has the highest level of water resistance in a smartphone we'll leave to Sony's marketing boffins.
What we will do is repeat what Lewis said about the then-rumoured Xperia ZR late last month, and that's that it combines elements of the Xperia Z with aspects of the smaller and lesser Xperia SP in a not unattractive package.
The display, for instance, is a fairly modest 4.55in 720p effort, but boasts the same HD Reality display and Mobile Bravia Engine 2 wizardry as the flagship Z to make up for it.
Sony is clearly pitching the Xperia ZR as an underwater imaging specialist, as together with its improved waterproofing skills it also boasts a 13MP Exmor RS fast-capture camera with a dedicated hardware camera button, full HD video capture, HDR mode for photo and video plus 15fps burst mode.
However, its waterproofing is freshwater only, so even if you have made sure all seals and flaps are covered up, you won't be able to take it to the high seas or anything, even if it's just the 1.5m high seas.
The more mundane details: a 1.5GHz quad-core Snapdragon S4 Pro chipset, 2GB of RAM, 8GB of microSD expandable storage, 4G LTE, NFC and Android 4.1 Jelly Bean.
You'll have to wait until Q3 before getting your hands on one, however, and Sony isn't talking prices yet either.
