Hello everyone,
I am looking to purchase my first fine watch and have a couple of questions for you experts before i do the purchase 
I am down to 4 watches.
1. UN marine diver with rubber or steel band (maybe i should get both bands?)
2. blancpain fifty fathoms with rubber
3. breguet xx aeronavalle with leather
4. jlc master compressor dualmatic with leather
i really like the UN, but i wanted to ask how it compares in quality/ prestige/ keeping its value with the other 3 brands. is UN as well known and respected as blancpain and breguet? can you please offer some insight into either of the above listed watches?
so far, i have seen all but the breguet in person, but am going to vegas later this month and i hope they have it there so i can try it on and see how it looks like in real life. (i cant find it in houston)
finally, is it safe to go with discount websites that are dealers, like prestigetime, or are they fraud and not worth the risk? is it customary to negotiate a price at a dealership and what discount can i expect. i am not looking for specific amounts, more like a percentage guidance so we dont break the rule of discussing prices 
thank you in advance for your advise and help.
Ason
