Hybrid-style instruments are always my favorites as they not only look nicer but also provide more references.  The new Altimeter for the Black Square (BKSQ) Dukes is one of them, which, in fact, is not only good for the B60 Piston, Grand and Turbine Dukes, but also can be used on all other MSFS aircraft.

Two versions were created for the instrument.  The Clean Version on the left in the video shown below deploys the scrolling effect used on the virtual cockpit, and the Extended Version on the right provides extra altitude precision readings via flipping digital style. 

Users can choose the one fitting their needs more.
