There are only a few rectangular timepieces that make the mark. The Lange Cabaret is one of them.
For one, they need to have a proper movement - one made for the timepieces and not slapping a round movement in a rectangular case. When Lange Cabaret was first launched in 1997, it came with the "regular" big date version. Later, they added the Moonphase to this timepiece and transformed the timepiece to a beauty!
The Cabaret is not as illustrious as the Lange One but still a very attractive timepiece. Under appreciated IMHO but for those who own one, they are the few who definitely enjoy the understated beauty. Congrats to Dr. Ma on his ownership of such a fine timepiece.
