Everest offers sets of Rolex replacement spring bars for different Rolex models. The spring bars are custom made to the exact tolerance, size and quality that Rolex uses. The spring bars offer Rolex owners an affordable option for replacement spring bars. These spring bars are exact replacements for the Air-King 116900. The spring bars measure 1.8mm thick by 20.0mm long. This is the Air-King without crown guards. For the newer Air-King ( 126900) please choose spring bars that are 21mm x 1.5mm from our spring bar collection.
