That looks like a good PO dial pickup, the price is right, if the pearl is centred like the photo shows it will be a good alternative for modding.
btw I may be hanging a good source here but theres a seller on one of the watchnet called valiola who sells all sorts of mish mash of parts, often its possible to find donor stuff on his listings sometimes at good prices. I've bought gen PO parts from him before, worth keeping in mind. Just be sure to check the pics carefully sometimes the bezels are without inserts etc. http://forums.watchnet.com/index.php?t=showposts&id=65425&rid=0 http://forums.watchnet.com/index.php?t=tree&goto=540150&rid=0
