I have to agree there have been quiet a few people coming into this forum to 'test the waters'.

First of all nearly everything made by Porsche has a suggested retail price. (Which can easily be found on the internet) or calling your local dealer who has a big book full of Porsche parafanalia. If you are selling nearly new or second hand then obviously the selling price would be lower than the suggested retail.
How much less to charge can be figured out by going to Ebay and doing a search to see what people are bidding. Or visiting a wrist watch forum.

And I don't think the seller of this watch is fooling anyone. C'mon. Most of us that bought our cars with moolah from earning a living and weren't born yesterday.
If the seller was truly just gauging the 2nd hand price there wouldn't have been a need to post the pictures of the actual watch in question. A model number or serial number, with brief description would have sufficed if getting replies on 2nd hand value was the only objective.
