Rolexx 1601 is within my budget?
whats the size and thickness of it?
Rolex 1601 is 36mm. Should hit the upper end of your budget, about 5k. Mind you, some of them might probably be 40+ years old so you'd need to make sure it's running well.
The Junghans is very nice, very clean and neat and should be within budget for a brand new watch. Try the shop in 1 Mont Kiara.
