Abstract: A device for measuring the concentration of a gas constituting the ambient air includes a wristwatch comprising a watch case (13) containing a watch movement, members indicating the time (1, 3, 9) visible through a glass of the watch case (13). In addition, the wristwatch comprises at least one sensor (11) arranged to measure the concentration of a gas constituting the ambient air. The wristwatch also includes means for actuating an alert when reaching or exceeding a threshold of the gas concentration measured by the sensor (11). The device includes two operating states, a “time” state and an “alarm” state, wherein in the “time” state, the members indicating the time (1, 1?, 3, 9) indicate the time and the sensor (11) permanently measures the gas concentration without displaying it or activating the alert.

Abstract: A watch can include one or more input components, such as a crown for receiving input from a user. The crown can be an assembly of multiple parts, for example, to provide aesthetic, structural, and/or functional attributes. The parts of the crown can be assembled in a manner that resists separation during use and when subject to environmental influences. For example, the assembled parts of a crown can be resistant to separation while a user wearing the watch is swimming, bathing, or sweating. The assembly can be secured by both mechanical mechanisms and chemical mechanisms.
