I am new to watches and looking to purchase my first Datejust. I would welcome anyone's advice on this watch which has caught my eye.

 

I assume this is a 16030. The damage around the lume plots is pretty severe. Also, I'm not sure that it's the same watch in the first two photos. In the first photo, the case and bezel are badly over polished. In the second photo, the engine turned bezel has sharp features and the lugs are thick and sharp. Also, the minute hand in the second photo seems to have a different color lume in the minute hand. The dial is the same. Weird stuff going on.

Many thanks for your help. Much appreciated!
