JR East Yamanote Loop by Jaybon

There’s a new watchface on the Rebble App Store!

@Jaybon says

Your wrist becomes a JR East Yamanote Line platform — and the station tells the time.

The Yamanote Line circles central Tokyo in about 60 minutes, so this watchface turns one loop into one hour. Every two minutes the nameboard advances one station around all 30 stops: at the top of the hour you’re at Tokyo (JY01), rolling station-by-station back around to Yūrakuchō by :58. Which station is showing tells you the minute — and for the exact time, just read the platform clock in the corner, the way every JR platform has one.

It’s a real sign at every moment: the correct JY station number on the badge, the authentic station name in kanji, hiragana, and rōmaji, and the actual neighbouring stations on the green direction bar. When the station changes, the sign slides in like an arriving train and settles onto the platform.

Features
Authentic Yamanote nameboard (駅名標 ekimeihyō) — JY number badge, station name in kanji / kana / rōmaji, and the green directional arrow bar with the real adjacent stations.
Tells time the Yamanote way — one loop = one hour, a new station every two minutes across all 30 real stops, anchored to Tokyo on the hour.
Platform clock for the precise time (12- or 24-hour).
Train-arrival animation on every station change — the sign slides in and gives a little settle, like a train pulling into the platform.
Tap or flick your wrist to peek — replays the arrival animation on demand (and lights the screen).
Fits every Pebble screen — rectangular and round, colour and black-and-white, with layouts tuned so the Japanese names always stay crisp and uncut.
Compatible watches
Pebble Time 2 (primary)
Pebble Round 2
Pebble Time / Pebble Time Steel

Settings
Open the Pebble app → this watchface → Settings:

24-hour time — switch the platform clock between 12- and 24-hour. (Default: 12-hour.)
Dark mode — flip to a black board with white text; the line bar stays Yamanote green. (Default: off.)
Peek on tap — turn the tap/flick-to-peek animation on or off. (Default: on.)

Update alert!

Jaybon just released version 1.0.1 of JR East Yamanote Loop!

Release notes

New Backlight on tap setting — turn off the tap/wrist-flick screen light if you’d rather keep it dark. (Default: on.)

Fixed overlapping neighbor names on long-name stations (e.g. Tamachi, between Takanawa Gateway and Hamamatsuchō).

Long station names (like Takanawa Gateway) now sit at the same height as every other station instead of riding high.

Release notes

Added a watchface menu icon (green “JY” badge) so it’s easy to spot and pick in the watchface list.

Yūrakuchō

Ending at Yūrakuchō implies the stations are going in a loop counterclockwise. Why not have the train loop go clockwise, like a clock?

Why not have the station at the northern end of the loop, Komagome or Tabata, at the 12:00 hour, instead of Tokyo station?

[tonarinototoro]

A couple more things to consider:

1. Since you already support Diorite and Flint, you might as well add Aplite. The code for Aplite should be identical.
2. The user sets 12hr vs 24hr time in the watch’s Settings. So, you don’t need to add this as a watchface setting. Instead, make this function call:
   clock_is_24h_style()

[tonarinototoro]

Better yet, have a watchface setting that allows choosing between:

1. clockwise; sotomawari (外回り; “outer circle”)

2. counter-clockwise; uchi-mawari(内回り; “inner circle”)

Jaybon just released version 1.0.3 of JR East Yamanote Loop!

Release notes

The nameboard now steps aside for Timeline Quick View: when an upcoming timeline event peeks in from the bottom of the screen, the station’s hiragana and rōmaji tuck away and the kanji name and green line bar slide to recenter, so nothing important hides behind the peek. Everything springs back the moment the peek closes. (Rectangular watches; round watches don’t show the peek.)

[tonarinototoro]

Bug:
Peek on tap doesn’t work for tapping the watch. It only works for flicking like a wrist flick.
