The Apollo 17 mission was commanded by Gene Cernan, who passed away in 2017. Cernan left history's last footprints on the lunar surface and "05:34 GMT" is printed in red on the dial of each model, indicating the exact time he took the final step.
Each caseback features a mission patch and is engraved with "45th ANNIVERSARY", "Limited Edition" and "a tribute to Gene Cernan". For the gold model, the central 18K white gold medallion uses an electroforming process to add the 18K yellow gold details.
