For reference - I recently sent my warrantied Swarovski SLC 10x42 WB (purchased in 2000) for a fix. (They only survive so many falls out of a treestand.) They perform a "free" standard clean and check and send recommendations/estimate of work to be performed. The customer decides what they want done. They said the left prism was damaged and minor scratches on the oculars and objective lenses that did not affect optical quality (they didn't try to sell me anything I didn't NEED, but maybe WANTED). Repair quotes were: $150 - replace left prism, $175 - replace all lenses.
Good luck.
