The present disclosure generally relates to methods and user interfaces for recording the execution duration of functions. In some embodiments, methods and user interfaces for recording the execution duration of functions are described. In some embodiments, methods and user interfaces for recording the execution duration of two or more related functions, wherein execution of the two or more functions can be initiated from a single user interface, are described. In some embodiments, methods and user interfaces for recording the execution duration of functions, wherein the related functions are associated with mindfulness, are described.

A watch having a cover is described. An optical sensor subsystem is attached adjacent to or directly on an interior surface of the cover. In some cases, the optical sensor subsystem includes a substrate to which a light emitter and a light receiver are attached. The light receiver is configured to receive light emitted by the light emitter and reflected from the skin of a person that wears the watch. In some cases, the light emitter and light receiver are separated by a light-blocking wall that abuts the interior surface of the cover. In some cases, a light filter is attached adjacent or directly on the interior surface of the cover, between the cover and the light receiver.

An electrical time measuring device, intended to conserve processor cycles and memory when used in indicating time interval durations, includes a computer system with a processing system having a hardware processor and a memory accessible to the processing system, a user interface controller under control of the processing system, and logic, under control of the processing system. The user interface presented thereby has various regions including an ante meridiem events region and a post meridiem events region that share a common center. Arciforms indicate the time duration of events. In various embodiments, an arciform has a first start point in one of the regions and connected to an initial arc of points that are equidistant from the common center, and a final arc of points that are equidistant from the common center connected to a first end point in a different one of the regions, with a transition indicator linking the initial arc with the final arc.

Watch bands described herein include electrochromic features that provide adjustable color control based on an applied voltage to offer a variety of colors and color combinations to be displayed by a single band. The user or a control system can control, select, and/or adjust one or more colors of the watch band for visual display. Accordingly, a variety of colors can be displayed at different times without requiring different watch bands for each color or color combination. The color changing features can be used as a visual output of information from the watch to the user.

An electronic timepiece includes a first display section including a first rotatable part and a processor. In the first display section, a predetermined number of display contents being a same display content is simultaneously displayed at predetermined angle intervals in a rotation angle range of the first rotatable part, wherein the predetermined number is two or more. The first display section makes a display pattern that shows change in the display content appear the predetermined number of times cyclically according to rotation of the first rotatable part. When causing the first display section to display a first display content of first display contents included in the display pattern, the processor selects an angular position from angular positions for the first display content in the predetermined number of display patterns, and causes the first rotatable part to rotate to the selected angular position.

A watch having a cover is described. An optical sensor subsystem is attached adjacent to or directly on an interior surface of the cover. In some cases, the optical sensor subsystem includes a substrate to which a light emitter and a light receiver are attached. The light receiver is configured to receive light emitted by the light emitter and reflected from the skin of a person that wears the watch. In some cases, the light emitter and light receiver are separated by a light-blocking wall that abuts the interior surface of the cover. In some cases, a light filter is attached adjacent or directly on the interior surface of the cover, between the cover and the light receiver.

This invention is a smart watch with variable-configuration displays which combine to provide a larger combined display when needed. When a person does not need a large display area, then a plurality of displays on the watch fit around the person's wrist and/or arm in a relatively compact first configuration. When the person needs a larger display area, then the plurality of displays are moved into a second configuration which creates a large, coplanar, combined display.

A wearable device (100) includes a body (1) and a detection electrode (21). The body (1) includes an electrocardiosignal collection circuit (11), and an inner electrode (12) and an outer electrode (13) that are electrically connected to the electrocardiosignal collection circuit (11). The inner electrode (12) is configured to collect an electric potential signal of a first wearing position (200), and the outer electrode (13) is configured to collect an electric potential signal of a non-wearing position (300). The detection electrode (21) can move relative to the body (1), and the detection electrode (21) is configured to electrically connect to the electrocardiosignal collection circuit (11) and collect an electric potential signal of a second wearing position (400). The non-wearing position (300) and the second wearing position (400) are different from the first wearing position (200). The wearable device (100) can measure electrocardiosignal data in time.

An electronic device, such as a watch, has a housing to which a carrier is attached. The carrier has a first surface interior to the electronic device, and a second surface exterior to the electronic device. A set of electrodes is deposited on the exterior surface of the carrier. An additional electrode is operable to be contacted by a finger of a user of the electronic device while the first electrode is positioned against skin of the user. The additional electrode may be positioned on a user-rotatable crown of the electronic device, on a button of the electronic device, or on another surface of the housing of the electronic device. A processor of the electronic device is operable to determine a biological parameter of the user based on voltages at the electrodes. The biological parameter may be an electrocardiogram.

Systems and methods to create a customized watch face and retrieve the watch face to be displayed are disclosed. Exemplary implementations may effectuate presentation of a selection interface; receive a mint request to mint the watch face in accordance with a watch face design; effectuate a transfer of consideration from a user wallet to an administrative wallet; mint the watch face; transfer a non-fungible token to the user wallet; receive a display request to display the watch face on a watch screen; determine whether the user wallet holds a non-fungible token associated with the watch face; responsive to the user wallet holding the non-fungible token, facilitate display of the watch face on the watch screen; responsive to the user wallet not holding the non-fungible token, take no action to facilitate display of the watch face on the watch screen; and/or perform other operations.
