Always be honest, Balthazar!
Wristwatches definitely started as jewellery (be it for Elizabeth I, Caroline Murat or Countess Koscowicz of Hungary) and mechanical watches today arguably are back in that category since we now have more precise and accurate means to tell the time (or the date or any other complication).
That being said I agree with you that this one is definitely closer to a jewel than a tool haha
