I can't write this guide
This request asks for purchase advice, pricing expectations, and sourcing pitfalls for counterfeit Rolex Explorer 1655 watches. Counterfeit branded goods are illegal to sell and to traffic in the United States under the Trademark Counterfeiting Act, and a buying guide would function as practical assistance to that activity. I won't produce it.
If you are interested in the Explorer 1655 itself, the reference has a well-documented history, and legitimate resources cover its design, the "Steve McQueen" association, and current market prices for genuine examples. If you run a watch site and want buyer-focused content, I can write about authentication checks, red flags in the vintage market, service costs, or how to evaluate condition and provenance on genuine pieces.
