My first post here thanks to MMMD referring me to the forum as I bid against him during the lightning G381 sweepstakes..

The eBay best offer pricing has changed but you can still figure out the final price with a little searching. I looked on my iPhone and it showed the final price for the A386 that sold yesterday. You can search the completed listings on your desk/laptop and add enough similar items - ie Zenith El Primero watch as your basic search. The results will still show the best offer asking price but will sort it by price even showing the best offer asking price. So the A386 from yesterday will show a $8,500 price sandwiched between another Zenith watch selling at $4,700 and $4,500. The more items in your search results will narrow it down further.
I guess eBay hasn't changed the mobile application for the smartphones yet because mine showed the price of $4,600 for the A386 right off the bat.
Here's a couple of pics to show what the search will look like.
