Digital Controls and Timing

Digital watches assign several jobs to a small number of buttons. Their manuals matter: Casio's 3525 and 3495 modules, for example, use different light-button assignments. A familiar case shape is not enough to infer a button map. Casio 3525 guide, Casio 3495 guide.

In the atelier

The visible Digital watch controls are labelled equivalents of the original model's physical controls. Use those labels rather than a maker's sequence. Supplemental Set time and Set alarm actions expose settings without hidden long presses. Retro LED instead uses Display and Set; it has no alarm or stopwatch.

Set, apply or cancel

Set time opens a draft local date and 24-hour entry time, plus a 12/24-hour display choice. Apply settings confirms the draft; Cancel or Escape discards it. Invalid dates and nonexistent daylight-saving times are rejected, not rolled into another day. A repeated local time uses its earlier occurrence. Settings change this session's clock offset, not your device clock.

Elapsed time and split

Start, pause and resume the LCD stopwatch. Split holds its reading while elapsed time continues; Release split catches up. Reset requires a stopped stopwatch. Classic stops at 59:59.99; Rugged stops at 23:59:59, displaying hundredths during its first hour. Neither silently wraps to zero. Changing the wall clock does not reset elapsed timing.

Rugged alone adds a countdown from 1 second to 24 hours. Zero is invalid. Pause before resetting it; reaching zero produces one completion notification and does not repeat automatically. This is not a mechanical chronograph: the analog chronograph illustration remains noninteractive.

Alarms and session limits

Each LCD has one armable alarm. It is a muted, in-page demonstration with no audio adapter. There is no OS notification, guaranteed background wake or reliable reminder when the page is closed or suspended. Returning to the page reconciles the instrument without replaying a backlog of alerts.

Appearance edits and camera changes retain the current instrument session. Loading a study or character, changing module, and resetting the watch start a new session; saved designs and shared links do not carry running stopwatches, alarms or settings drafts. Repeating an active character can reset its instrument without creating another appearance-history step. Light lasts two seconds on LCD; Retro LED's Display wake lasts five seconds. Night only changes scene lighting. These bounded instruments illustrate interaction, not hardware accuracy or timing suitable for safety-critical use.
