Being poisoned by Privateday7 to Omega dress watch

I manage to snap this 2 and another 1 not in the picture

All seamaster 30 with similar dial, ss case ss hand, ss case gold hand ( both in rhe picture) and gold case gold hand.
Clean em up, polywatch the glass and put new strap on these two.

Anyhow, does anyone know where to buy seamaster 30 gold crown ... Since mine come with non original crown.
