datewheel replacement for datejust

[brownoysterdj]

Hey, I just recently purchased a Oyster Datejust whitegold and it came with some wierd aftermarket datewheel and I want to replace it...I found a site with a bunch of replacement wheels, just wondering which of the wheels would fit my datejust

And if anyone has a reccomendation on a place to find them cheaper thatd be cool but 40 bucks is hard to beat :)
