I just wanted to fade it a little but it would not go, dings and scratches it will pick up along the way with me any way. but ubis was just perfect
fitted with an ofrie pearl
If you want to age the insert, i tried and failed on the PMWF ones nothing but violent action would fade them. In the end Ubi gave me a very nice faded MBW one for my 1680
Just have a read on the forum and you will find lots of tips, me personally i just wear them, but some people carry them round in a pocket full of coins for a day or so.
As every one above has said it is very dependent on your budget and the research you put into it, the new 1655 is a good starting point and some thing you can wear, it just needs a bit of aging.
