While I heard the question often until recently, there are more and more btcoin-friendly merchants every day.
I just bought a watch from a well known russian watch manufacturer who has started accepting bitcoin payments in July.
The delivery took a little while (two weeks from Moscow to Paris) but turned out to be flawless with tracking number and all.
The web shop displays the bitcoin logo on its
home page.
Here is the watch:
For the record, I paid 3.67 Bitcoins, shipping included, on Juy 11 (tx id = 0d2c57fd151368fb56266be480df8a399ebb5f50625d3f7fccef8ceb4abb40bf )
As long as other online watch retailers are NOT accepting Bitcoins, I'll probably stick to Raketa watch only.
