This 4K-video with rich technological depth will show you the difference between the OMEGA Seamaster Diver 300m & the TUDOR Black Bay Ceramic and give you some useful information to better understand the only thing both divers have in common: the Master Chronometer certification by METAS, the Swiss Federal Institute of Metrology.

Comparing OMEGA and TUDOR is like comparing apples and oranges. One cannot compare apples and oranges!

Whilst the OMEGA is a real luxury diver, the TUDOR is a very, very good diver, but not a luxury watch. TUDOR has a clear positioning below ROLEX and you must compare the brand to LONGINES and not OMEGA. OMEGA compares to ROLEX and ROLEX compares to OMEGA. TUDOR does NOT compare to ROLEX, therefore you cant compare TUDOR to OMEGA, with or without Master Chronometer certification.

The METAS Master Chronometer certification is comprehensive and covers the main functional characteristics of a watch including precision, resistance to magnetic fields, waterproofness and power reserve...

Please download the the process of certification of mechanical watches is in accordance with the METAS requirements N001 from the METAS homepage in English: link

Too much? Ok, here in In brief:

Swiss Made
Certification by the Swiss Official Chronometer Testing Institute (COSC)

Smooth functioning when exposed to a magnetic field of 15,000 gauss and precision following exposure
Waterproof in accordance with ISO standard
Power reserve checked
