What about Cartier Santos? It is the first pilots watch. Alberto Santos Dumont got it especially made so he could time his flights and he wore it when he was trying to increase his fight times.

That's correct, the Cartier Santos is the first recorded wristwatch be used as an instrument in the cockpit. However, the IWC Pilot's Watch set the standard for what we consider today as a pilot's watch - the readability, leather strap and anti-magnetism, among others. 🙂 Hope this helps!
