Casio GA-2100 (fan)

A tribute to the octagonal square-shaped shock-resistant classic, rebuilt as a standalone Wear OS watch face — an ANA-DIGI layout with applied hour markers, a DAY-OF-THE-WEEK subdial at 9 o'clock and a live LCD panel at the bottom right where the digital time sits above the running seconds.

COLORWAYS
• CasiOak — all-black case and dial with grey applied markers, the signature stealth look
• Blue — ice-blue bezel and dial with tonal markers
• White — clean white bezel and dial with pale markers
• Yellow — bright yellow bezel and dial with olive printing

FEATURES
• A LIVE LCD PANEL at the bottom right: the DIGITAL TIME with its separator on the top row and the BIG RUNNING SECONDS underneath, in real LCD segment digits over the pale panel — it actually ticks, it is not a printed picture
• THE LCD FOLLOWS YOUR WATCH: set 12-hour or 24-hour time in your Wear OS settings and the panel switches with it. In 12-hour mode the leading zero stays blank, exactly as on the real watch; in 24-hour mode it is shown
• A LIVE DST INDICATOR: the "DST" mark beside the LCD sits dimmed like an unlit segment and LIGHTS UP by itself while your time zone is on daylight saving time
• A DAY-OF-THE-WEEK SUBDIAL at 9 o'clock, its printed SU M T W T F S scale swept by its own small hand
• FOUR TAPPABLE BUTTONS on the bezel — tap ADJUST for Settings, LIGHT for the flashlight, MODE for your music player and START for the Clock, where the alarm, the timer and the stopwatch live
• APPLIED FACETED MARKERS all around the dial and the octagonal "CasiOak" bezel graphic that gives the watch its nickname
• Broad, tapered hour and minute hands in pale luminous cream outlined in black, over the centre cap
• Printed dial text kept as on the real watch: "G-SHOCK" and "CASIO" in the upper half, "WR 20BAR" at 3, "DST HND" beside the LCD and "MUTE ALM SIG" under it, with the alarm and signal indicator marks lit
• Printed bezel text: "G-SHOCK" at the top, "PROTECTION" at the bottom, "ADJUST", "LIGHT", "MODE" and "START" around the sides
• A true ANA-DIGI — NO analog seconds hand (the GA-2100 does not have one), NO chronograph, NO extra subdials, NO date window

STYLES
Eight in total: each of the four colorways comes in two views.
• Standard — the whole watch, bezel text and all
• Zoom — the dial fills the screen edge to edge, so the markers, the LCD and the day subdial all read bigger
Pick yours in the editor — the whole watch changes together, dial, bezel, hands, subdial and LCD.

HOW TO USE THE BUTTONS
The four labels printed around the bezel are live. Wake the screen first, then tap the label itself:
• ADJUST (upper left) — opens your watch Settings
• LIGHT (upper right) — opens the flashlight
• MODE (lower left) — opens your music player
• START (lower right) — opens the Clock (alarm, timer and stopwatch)
Tapping anywhere else on the face does nothing, so you will not trigger them by accident.

MORE
• Always-On Display (AOD) friendly: the dial, the LCD panel, the digits and the day subdial all hide, leaving only the hours and minutes so they stay legible on black — measured at about 4% lit pixels, far below Play's 15% limit
• Standalone — no phone or companion app required
• Built with Watch Face Format for smooth performance and long battery life
• Wide device support: runs on Wear OS 5 and later (no blend modes required)

HOW TO CUSTOMIZE
Long-press your current watch face and tap Edit (or open the face from the picker), then choose your style — CasiOak, Blue, White or Yellow, each in Standard or Zoom.

COMPATIBILITY
Wear OS 5 and later, round displays. No blend modes are used, so it runs across a wider range of Wear OS 5 devices — not limited to 5.1.
