I own but don't wear Rolex watch(s)
I don't own a Rolex watch.
This is true, that's why classic Heuers are very desirable pieces. Modern Tags, not as much. Most watch brands don't have their own capacities to manufacture all components inhouse, plus this will make them very expensive. That's why most brands buy ebauches from ETA or Sellita (like Oris), modify them, and give them their own calibre names. But, this is going to change now that Swatch (owner of ETA) has stopped supplying movements to its competitors. We are going to see a lot of in house movements pop out in the coming years.
kelangan daw sa watchworks lang para yung gasket original at waterproof..pag sa iba papasukin na daw ng tubig...
