nope usual brand new or preowned watches there's no tax refund if you purchase from these store. But they're this new pre own watch store that just open few months ago sell brand new watches with refund. i don't how they do it. Example PP 5320G-001 retail at $129,000 SGD they are selling at $109,620 with GST and $ 101,500 without GST which is 15% below boutique price. what amaze me even if the watch model like RM, AP and PP that is sought after selling above retail price as long its brand new you can get GST refund.
