The Apple Watch 49mm Natural Titanium Milanese Loop retails for S$279, dropping to S$250.70 on Apple's EPP. Neither Lazada nor Shopee carry it, and with two titanium colours across three sizes, I picked the small to fit my 150mm wrist.
Apple Watch Series 3 in Space Black Stainless Steel with Milanese Loop isn't sold in Singapore. None of the high-end models, Stainless Steel, Edition, or Hermès, are, because they come only in GPS + Cellular, unsupported by local telcos.
I bought the Apple Watch 42mm Milanese Loop for S$218 from the Apple Online Store, since it was sold out at every authorised reseller. I ordered on 2nd July 2015 and received it on the 7th, despite the five-to-seven-day shipping.
