The movement is the Miyota Y652 which is no longer available. If there are any issues with the movement Breitling no longer have spares so it is toast. I have seen those movements for sale though.
It is an earlier version of what was to become the Aerospace. This has the Superquartz movement and is COSC.
Similar styles are he B1, Airwolf Raven, Hercules and Emergency

I went with a more modern Aerospace for a bit more but is is fully supported by Breitling.
As it is titanium it is very light. And very good lume.
