So of course there is a difference in how an expensive watch is made and how a reasonably priced watch is made. But is one better as a WATCH than the other one? Or is an expensive watch even more comfortable to wear than a high end one? No. Once a certain level of quality is met, say a $100-200 Seiko, you are past just the utility or even nice looks, since I see many cheaper items that look as good or better.
One is better as art or as a luxury item and for personal satisfaction or a status symbol. At the end of the day, if you know it's 4pm, your wrist does not hurt from wearing it, it's a watch. If some guy spent 5 hours polishing a gear, used gold and platinum, packaged it in a fancy wood box, that is not a watch, that is a luxury item. It is the exact same with cues or anything else that gets to past just good enough. If you can make balls with it, the balance is good and it does not rattle when you use it, it's a good enough cue. Adding a name to it or using rare wood or fancy gems or metals does not make it inherently a better cue. A while ago they had some 10,000 dollar phones out, difference was it was made of expensive stuff and was exclusive, grandma at the other end of the line would have no idea if you called her on that or from your $40 10 year old Nokia.
Usually when someone spend a bunch on something fancy, they are not getting it for themselves, they are getting it so others know they have it. No one would buy a Rolex if it was hidden behind your shirt all the time or just used to tell time.
