Amazing, I would contact Richard Crosswaite his website is heurmonaco.co.uk, you should provide him pictures as depending on the condition, it would determine the price of it. But 1133 Monacos in mint condition are expensive, I'll just give you that much information ;-)

: Good Morning,

: I have in my possession, a Heuer Monaco that my dad purchased in
: 1973. He left it to me, and all it does is sit in a safe deposit
: box. The model number stamped on it is 1133, and the opposite
: side has a number 160247. It works, it does not have the
: original band on it. Plastic lense, quite a nice watch. does
: anyone have a clue on how much it's worth? I have seen price
: lists, but they date to 2007. I would be glad for any help. I
: can send pictures to help.

: Thank You
