Have you ever seen how golden watches are made? You may join us and visit “NIKA” company to see how it makes over 25 thousand precious items monthly.
This 12 kg bar costs 20 million rubles (about 650 thousand dollars).
Specialists check fineness of alloys made at this factory as well.
The gold bar 12 cm long and 5 mm thick turns into a band up to 2,5 m long and 0,25 mm thick. It goes through the shafts of the rolling mill more than 50 times.
Two parts of a watch case are connected.
They stick small parts with vaseline (solder).
They take a small piece of gold with tweezers, dip it into vaseline and stick to the case.
On such a tape the cases will go to the furnace where the details will smelt and solder while vaseline will evaporate.
Ready golden cases come out here.
