This was my signature scent for quite some time, and I haven't yet come across something exactly like it. I guess you tried the older metal tube Emporios, too; one of them was a little like white. Of course there are other citrus musks, e.g. Benetton Sport is a quite cheap one and not that bad, but those I tried lacked the soapy saltiness of White.
A word of caution, though. My bottle has turned within 2-3 years, it had gone quite sour and wasn't as pleasant as in the beginning. If you are going to wear this only occasionally, maybe it would be good to get a 30ml bottle first.
