Vintage Chronograph Watches

I was planning a trip to Singapore and was wondering where I could go to get vintage electronics. Also, if you know the best electronics plaza for new stuff, I would like to know about that too. Thanks a million in advance!!

I am looking for casio vintage watches to be sold outside Singapore. But the items are already in Singapore. Looking for authentic and good price. And also looking for BAPE GShock.
