Now I'm even more confused. From what I see on the net, Tantalum IS Tantalium. Both share the same chemistry symbol of Ta.
When I looked up OP official website, 192 case and bezel are made of 'brushed tantalum' and 'polished tantalum' respectively.
Then when I looked up 'tantalum', I get the notion that 'Tantalum... formerly tantalium... has the symbol Ta and atomic number 73'. Different names... same element.
When looking up further, I also learnt these:
"... Tantalum is alloyed with steel to increase steel's ductility, strength and melting point."
Tantalum density is 16.4 g/cm3. Titanium is only 4.5 g/cm3. Iron is 7.874 g/cm3. Gold is 19.282g/cm3.
Seems like Ta feels almost as heavy as gold. Could it be that the so-called Tantalium 192 is indeed mixed with steel and not pure Ta?

The wrong thing is being argued. Tantalium is not tantalum. From a gen 192 advertisement
"Manufacturer: Panerai

not tantalum....but just for a scientific arguement
titanium = Atomic mass 47.867(1) g/mol
tantalum = Atomic mass 180.94788(2) g/mol
