Veľmi zaujímavý článok.
O použitých materiáloch tež sem tam nejaká zmienka - no očividne sú vo Swatch group velkí tajnostkári - vystrihnuté z článku " The differences with the ETA 2824-2 go even deeper; it’s not even made from the same material. Exactly which materials have been used in the different Powermatic calibres, Swatch Group doesn’t tell, but our information tells us that the steel alloy is a bit different from usual movements, the so-called ARCAP alloy, which is anti-magnetic. (For the real metal-heads among us: it is made up of a combination of nickel, copper, cobalt, tin, lead and zinc.) In some cases, ETA even adds plastic materials to the movement."
