Ahhh, I didn't know that it was prefixed with a B
The complete model number for the 5712 is; 5712/1A-001 710.TNGT3
As far as I know, the 001 is the description of the dial.
I personally like the old moonphase design with the shiny moon.
Newer version

Yes it is a newer version of the 5712, which started to be available on the market from around 1.5-2 years ago. Note that the power reserve indicator has another dot after 48 hours (same thing on 'newer' 5712G and 5712R too).
