i had some indications, but because of the number of ROO models i was not 10000000% sure until i opened it up. then i looked at the seconds hand to see it "ticking" not "running." i didnt even check that because i could not imagine that the guy who looked at it would not have picked up on that. had i saw that, i wouldnt even have opened up.
good luck to my co-worker who has to relay the news.
as to condition, i have found that its not really a great indicator. even the fact it had no box and papers. when it comes to the very rich, a lot of these watches are impulse buys for fun or gifts to people who are not really watch lovers, especially if they are graduation presents. its just a fun trinket to play with until its broken. the box and papers are like gas station receipts and get thrown away or lost and forgotten about.
resale is not a factor when some of these are bought or received. sad, i know. but different strokes for different folks. we have bought some fantastic pieces that were all messed up and no box or papers. obviously the cost to repair is significant and the resale value is less, and we therefor offer less, but for the right price, they can be great buys.
