Off-center Tourbillon

An off-center tourbillon is a type of tourbillon mechanism that is positioned off the central axis of a watch movement, typically at the 6 o'clock position on the watch dial. It consists of a rotating cage that houses the escapement and balance wheel, which makes one rotation per minute. This constant rotation serves to counteract the effects of gravity on the delicate escapement components, improving the timekeeping accuracy of the watch in various positions.
