Omega 8506 is still very good.
Omega watches use patented mechanical movements and silicon hairspring movements that last for four years. It can be seen that the Omega watch brand is also very confident in its own quality.
Omega has a long history of more than 100 years with its leading watchmaking skills. The previous Superba series was also the only watch worn on the moon. Omega not only has a large number of accurate records, but also created the only mid-mounted tourbillon watch in the world's watch brand series.
