Just needs a wristband :)

[@dabulldog8014]

is the balance wheel more efficient than a pendulum?

[@jacquesfavre999]

Probably not, but it is more portable

[@theofficialczex1708]

And it's not as affected by the movement of the timepiece.

@@jacquesfavre999 and it looks cooler than a pendulum. I would also be curious to know about how accurate it is
