Type 16 names in the basic 16 set, from Mainspring barrel to Watch dial. Read the complete labels beside the representative pictures and compare names such as Mainspring and Balance wheel. Auxiliary diagrams show placement relationships. They are not validated designs for tooth profiles, dimensions, clearances or assembly function. Do not use the pictures to plan disassembly, repair or part replacement. The isolated forms support reading and vocabulary; they do not establish that a real movement will work when assembled in the pictured arrangement.
