Calendar and a strip of calendars attachable to a watch strap, and method of attaching the same thereto.

摘要

A calendar chip (20) which is easily attachable to the band (D) of a wrist watch (A), includes a tubular flat body of a plastic film practically shrunk by heat in the widthwise direction. The chip (20) has first and second layers (16, 18) contiguous to each other, said first layer (16) including on its surface calendars (26a, 26b) for a plurality of calendar months successive in time and disposed in the lengthwise direction in order of time. Such a calendar chip (20) is slipped on a wrist watch band (D) from the end of the band towards a part near the watchcase. Then, the calendar ship (20) is subjected to heat treatment and is practically shrunk in the widthwise direction. Thus, the calendar chip (20) is fixed to the watch band (D). In the thermal treatment, a hair dryer is conveniently used. A plurality of calendar chips including a calendar for a single calendar month or calendars for a plurality of calendar months successive in time may be united into one strip of calendar chips in advance, so that a required calendar chip can be torn off from the strip in use.
