I'm guessing you are in North America.. in which case, try Craig at Chronodeco.com.
However.. restoring these old divers aren't easy.. I don't mean the servicing, but external parts, crown, bezels, inserts etc aren't readily available, so even an accomplished watchmaker/restorer can only do so much.
