I built many 18K solid gold president replicas in the late 90's and early 2000"s. The bracelets then cost me 1600.00, today 4200. The 18K cases were 800.00 plus the 18K solid gold aftermarket fluted bezel was 125.00 They were to say the least, a very heavy and beautiful watch. My bracelets and cases had no markings on them other than 18K. The people that bought them still wear them today. I did see 1 or 2 18K gold aftermarket yachtmasters with 18K gold aftermarket bracelets, with no markings, but I never built one, and have not seen any since. Perhaps this is one.
