It's not gold plated but here is the listing from when BK offered the TW Sub. It was at its time the best option for a reasonably priced 16610. It used a 2836 so the case was fat, the stock cg needed work, the bracelet had solid mid links, clasp had fat crown etc... But after WM9 left it was the best until TC reconnected with the factory making WM9. There are some good pics here, so give it a look:

Unless you find one in the m2m section probably best option is a TC case, bezel and bracelet and send off to get plated and find a gen dial, hands, insert and crown. Pair with a y3135 unless you wanted to clip the gen dial feet.
