The Enso Pearl is a unique timing device designed to provide a serene and distraction-free experience for managing time. It combines the functionality of a clock, alarm, and multiple timers with a focus on abstract time visualization and soothing audio alerts.

Function Description:

The Enso Pearl serves as a multi-functional time management tool with the following core capabilities:

Clock: Displays the current time in either 12-hour or 24-hour format.
Alarm: A single alarm function that can be set, toggled on/off, and snoozed. The alarm utilizes soothing chimes from Tibetan & Japanese singing bowls and bells.
Timers (T1, T2, T3): The device features three independent timers, each highly configurable for different timing needs:
- Interval Timing: Allows for a sequence of two or more separate sub-timers (Intervals). Each Interval is set for a specific duration, and the device counts down through them sequentially. Each timer can hold up to 99 Intervals.
- Repeat Timing: Enables repetitive timing of a single duration, up to 99 repetitions.
- Stopwatch Function: A count-up timer that starts from zero.
Enso Ring: A distinctive visual element that slowly "brushes" around the clock display, abstractly showing the relative amount of elapsed time. This feature aims to free the user's mind from the distraction of a numerical countdown.
Audio Alerts: Provides gentle chimes from Tibetan & Japanese singing bowls and bells to indicate the completion of a timer or alarm. The volume and tone of these alerts are adjustable.
Backlight: A temporary backlight for visibility in low-light conditions.
Numerical Display Hiding: Allows the user to hide the numerical display during a timer, leaving only the Enso Ring for abstract time visualization.
