The Lumia 925 feels very much a Lumia 920 in a new slim line aluminium shell, indeed, it shares many of its tech specs with the previous model. While the front and sides of the chassis are crafted from a single piece of aluminium, the rear is still polycarbonate, so it's not quite a unibody design.
For example, it uses the same 1.5Ghz dual core processor, has 1GB RAM and has 16GB of internal storage as standard. Some operators, such as Vodafone, have exclusivity on distributing certain variations of the device. In the case of Vodafone UK, customers will be able to get their hands on a 32GB version of the Lumia 925.
Official measurements of the handset are 129mm x 70.6mm x 8.5mm and it weighs in at 139g. To put this in some perspective, the Lumia 920 is 10.7mm thick and weighs 186 grams.
Disappointingly, none of the variants include the option of a microSD slot to expand onboard storage, so the majority of the devices are limited to 16GB plus 7GB of free SkyDrive storage. This leaves it somewhat constrained in comparison to other devices.
The location of the charging slot has moved from the bottom of the phone (where it is on the Lumia 920) to next to the headphone socket on the top of the chassis for the Lumia 925. Volume, power and dedicated camera shutter buttons remain on the side of the handset.
The camera hardware is also mostly the same as the Lumia 920 (although it uses a 6 lens Carl Zeiss arrangement rather than a 5 lens) meaning that it has an 8.7-megapixel sensor with optical image stabilisation and dual LED flash.
Naturally, there's autofocus too and the ability to capture 1080p HD video at 30fps.
There's also a front-facing 1.2-megapixel camera for video calling or still pictures.
