That's interesting, I was on their website last night having a look in their watch shop.
I'm always bewildered at where they get these estimates from, we shouldn't forget that they are trying to make as big a profit as possible so it is better for them if they go at higher prices, so even tho they hire 'watch experts' the estimates don't often reflect true value.
When is the sale? Would be interested to have a look. I think Speedmasters will definitely have their place in the sun in years to come, and rightly so.
