Document Type and Number:

WIPO Patent Application WO/2006/064556

Kind Code:

A1

Abstract:

A multi-function timepiece with a small hand, constructed such that plural layouts of a movement are possible without changing the dimensions and shapes of parts of the movement but only by changing assembling positions of the parts. A movement (201) of a multi-function timepiece has a first wheel train rotation center and a second wheel train rotation center. The first wheel train rotation center and the second wheel train rotation center are disposed at positions between the center (202c) of a main plate (202) and the outline of the main plate (202). Wheel train guide sections for rotatably guiding wheel train members are individually arranged at the first wheel train rotation center and the second wheel train rotation center. A wheel train for displaying time information or calendar information is rotatably provided at either of the first wheel train rotation center and the second wheel train rotation center.
