Sorry for the false alarm. I guess I overdid my "estimate".
In that case, i guess the Explorer is off the table
Explorer a bit out of budget, but I will suggest save few more month top up to explorer, if lucky can get below RM23k.
Return to the topic, RM20k can take a look JLC master control date, or IWC 3777, Mark 18 blue dial... This few is my favorite brand.
Personally I not so recommend Tudor, unless u own Rolex...
Last but not least, forget omega ba
