The calibre 51111 also features IWC"s Pellaton winding system for the automatic rotor. It is said to be a bit more durable than other automatic winding systems, and it also winds when the rotor moves in both directions. Plus, the Pellaton system uses a unique heart-shaped cam in the gear train which is interesting. Functionally I think it is cool that the Pellaton system is there, but for practical purposes most casual watch lovers won't understand or appreciate the differences from other winding systems. Speaking of which, IWC is actually pretty good at speaking to the right customer at the right time. If you look at their marketing as well as their products, they know when to tech talk it up with gear heads, or to just show cool timepieces and not go overboard which technical details when speaking to more casual timepiece fans.
ABTW: What specifically can you tell us about the three straps seen here?
The Commander II watch is 40mm wide in steel with a few dial styles and silver, gray, and black colors. Inside is a Swiss ETA 2836 day/date automatic movement. It appears as though some versions of the movement are Chronometer certified. At least the dial retained the quirky "Datoday" label on it. The Commander II arrives with a slightly higher-end brother, a new version of the Great Wall watch.
