AI market analysis

For buyers

The eBay median asking price of $6,113 is significantly inflated compared to the realistic $3,300-$3,800 grey market range; do not pay anywhere near that. Target the lower end of the established grey market range, around $3,300-$3,500, and negotiate aggressively given the watch's low liquidity. Exercise patience to find a seller realistic about market value rather than aspirational asking prices.

For sellers

Given low liquidity, avoid setting your price based on the inflated $6,113 eBay median, as this will lead to extended listing times and deter serious buyers. To sell efficiently, list competitively within the $3,600-$3,800 upper end of the grey market range to attract buyers willing to pay a fair premium. Be prepared for a negotiation as buyers are aware of the watch's true market value.
