He told the man he had to check the electrical panel in the bedroom closet, police said.
Later that night, the victim went into his closet and discovered his Patek Philippe wristwatch was missing, police said.
Detectives on routine reviews of items being pawned found the watch at an East Meadow pawnshop, police said. Tallman had a friend, who had no idea it was stolen, pawn the watch, police said. The watch was recovered, police said.
He is scheduled to be arraigned Tuesday on third-degree grand larceny charges at First District Court in Hempstead.
The repair company's Merrick office hung up on calls requesting comment from the owner.
Detectives ask anyone who feels they may have been victimized by Tallman to call Nassau County Crime Stoppers at 800-244-TIPS.
