Is there a guideline for a second hand Speedmaster. Like in % of new price to pay for a decent condition watch.

Please help!

Among all the great stuff there is a price chart, which will give you some idea of what vintage Speedmasters sell for

 

It depends - if you're selling one to me, a used one is only worth 20% of it's cost at an AD. If I'm selling it to you, it's worth 80% of it's cost at an AD.

Seriously, it depends on the model. Some are more sought after than others. Condition is a BIG factor also.
