The Barrel Complete is a pre-assembled unit that includes the mainspring barrel and mainspring, key components in Seiko NH35, NH36, NH37, NH38, and NH39 automatic movements. The barrel stores energy when the watch is wound, and the mainspring releases this energy to power the movement. This ready-to-use assembly ensures smooth operation and is perfect for repairing or replacing worn or damaged barrels.
Note: This Barrel Complete is not compatible with the 6R5 Series or 6R35A movements. While many parts are similar, the barrel and barrel lid shapes differ between the 6R55A and 6R35A, as shown in Image 2.
