Christies just sold a Monaco Sixty Nine (CW9110) with non-original papers and an "undated guarantee card" for 6000+ USD. Clearly people have money and clearly no idea about what they're buying. I don't blame Christies - they clearly advertised what they're selling (Cal 16 booklet for a Monaco 69!!!! )
I saw a Sixty Nine for less than £3000 the other day...
Sorry, my mistake. Christies sold the CW9111, basically the same as the normal Monaco 69, but autographed by an Indian actor (who was TH ambassador some years back). The watch essentially is the same as the conventional CW9110.
