Looking at the watches you listed, ur budget should top out at abt RM 30K, altho the Omega AT is in the under 20K region.
For that amount you have a lot of choices but u need to decide whether you want a formal dress, casual, sporty case. Then you have diver or flieger theme. Complications like date/day-date,triple date, MP,PR, chronograph, GMT, etc. Case material like gold, SS,titanium, ceramic (forged carbon is out of the budget).
For a budget of RM 30K I wouldn't rush and would consider a lot more options in brands besides the obvious Rolex, JLC, Omega such as Glashutte Original, IWC, Blancpain, AP (pre-owned),etc.. If you can accept the conservative style of Grand Seiko, that too is an excellent option.
If you review MWF threads such as watch gallery, watch review and What watch is on your wrist, it should give you a very good idea.
