    Indeed. And the stilted, badly translated company press release could not be more opaque. The Academy line is Zenith's super-haute horology collection - tourbillons & repeaters, and the Christophe Colomb is the line with the gyroscopically stabilized balance, but what is new about this iteration or why it's called the Hurricane escapes me. Certainly that chain-drive fusee thingy is new, but the rationale is not clear.

    I think its the fusée-and-chain mechanism but I'm not sure

    Yep, you're right, we posted simultaneously. But why?

    Well from memory the fusée-and-chain's main benefit was that it made mainspring torque uniform over the full duration of its unwinding, back when escapements used at the time were dependent on that, but my understanding is that modern lever escapements are entirely independent of mainspring torque due to being governed by the oscillation of the balance, rendering this unnecessary.

    That said, seeing the chain unwind behind the dial would look damn cool

    Correct.

    Incorrect. The mainsprings are now S shaped which helps counter the loss of torque in the last third.

    The backwards curve has more push.

    Perhaps it's called the Hurricane because it blows.

    That's a shame. Just checked and my lottery numbers didn't come up last night.
