So…
The SBDB005 - the first in the series - came out in 2012. The 007 - the Miura Limited Edition in 2013 and the 015 supposedly in 2016, but the serial number on mine shows a 2015 production year. The difference between the 005 and 015 is slightly different lume, it seems.
They share the hour marker and hand design with the SpaceWalk but retailed at about a tenth of the price.
The crown at 12 o’clock apparently ensures that ropes used in climbing don’t get tangled up with the watch - I will take their word for it 😉
It got discontinued relatively soon - I suppose the fairly wild design, paired with the large 47mm size were to blame 🤷🏻♂️
