A question for everyone, are rep cases made casted or forged? Many say they're made from solid block but what does that mean?
Forged is always prefered as metals are uniformly in one direction, unseen by the naked eye.
Bracelet are probably casted. There are cryogenic treatment services locally, i could probably strengthen my watch stronger than gen... Now if chinese rep follow japanese Kizen, they would consistently improve to outcompete the genuine, as Honda did with 1990s NSX beating the Ferrari it meant to imitate.
As you know, steel is alloy of many metal and gas elements. On periodic table, higher atomic number is a larger piece of element.. Over 1,000,000,000,000,000,000,000,000 atoms exist in 100 grams of element Fe (iron).
In alloys, getting large and small elements together to mix evenly isn't easy. Scientists are still struggling to fully understand the mechanics in metallurgy. Chrome, iron, silicon, nickel, copper, nitrogen - all varies in size.
Current high end method is, nano powered metal > forged > cut into final product > cryogenic treatment. In comparison of standard industry forged, the new method cost more, almost never done except for race car engines, military armor and spaceships... It is vastly superior in hardness without being brittle, scratch resistance, corrosion resistance and rust resistance.
