OmaWatch

A Garmin watch face in the style of a tiling Linux desktop. Two layouts, a code-editor look, and the colour schemes of the Omarchy desktop.

Layouts

• Neovim. Your values as code rows (hr = 54) around a cursor line that holds the time. A graph in a box at the bottom, like btop.
• Waybar. A bar across the top with the weekday as workspace numbers. The bottom edge of the bar fills with the value you choose for the top bar.

Features

• 22 colour schemes: Tokyo Night, Catppuccin, Gruvbox, Everforest, Nord and more.
• Four rows you can set, from 31 values: heart rate, body battery, elevation, steps, temperature, watch battery, floors, stress, step goal percentage, steps with the goal, floors with the goal, active minutes with the goal, VO2 max run and bike, weekly run and bike distance, pressure, calories, respiration rate, pulse ox, sleep score, recovery time, notifications, the four race time predictions, feels like, humidity, wind speed and rain chance.
• A top bar you can set: daylight from sunrise to sunset, step goal, floors goal, active minutes, body battery, watch battery, the day, stress, sleep score, pulse ox, or off.
• Temperature in the unit of the watch, or always in Celsius or Fahrenheit. Distance in the unit of the watch, or always in kilometres or miles.
• Two text sizes, normal and large.
• A graph of the last hours, from heart rate, body battery, elevation, pressure, stress, pulse ox or temperature.
• Always-on mode with dim digits that move every minute.
• Settings on the watch itself: hold MENU on the face and open its settings. No phone needed. The row values are in groups, so you find one quickly with the buttons.

Requirements

• A round AMOLED Garmin watch with Connect IQ API 5.0 or newer. 47 models, from the Venu 2 to the Fenix 8.
• Temperature, the weather values and the sunrise and sunset times come from Garmin's weather data. The watch gets them from the phone, so they stay empty until the first sync.
• VO2 max, the weekly distances, the race predictions, the sleep score and the pressure come from Garmin complications. A value stays empty until the watch has enough data for it.

Install

Get it from the Connect IQ Store, or build it yourself.

Build

1. Install the Connect IQ SDK Manager, then the SDK and the devices you want.

2. Make a developer key:

   openssl genrsa -out developer_key.pem 4096
   openssl pkcs8 -topk8 -inform PEM -outform DER -in developer_key.pem -out developer_key -nocrypt
   

3. Build for one watch:

   monkeyc -f monkey.jungle -d instinct3amoled45mm -o bin/omawatch.prg -y developer_key -w -l 3
   

4. Run it in the simulator:

   tools/sim.sh bin/omawatch.prg instinct3amoled45mm
   

   On Arch the simulator needs sdk/compat, because Garmin builds it against webkit2gtk 4.0. The script sets that up. Without it, start the simulator with connectiq & and then run monkeydo.

To put it on a watch, copy the .prg file to GARMIN/Apps on the watch, then disconnect the cable.

Fonts

The face uses JetBrains Mono, converted to bitmap fonts with tools/mkfont.py. To make every font for every screen size:

tools/genfonts.sh

There are two sizes of the text fonts, for the text size setting. Only the pair the watch needs is loaded. The row and small fonts hold the Latin, Greek and Cyrillic alphabets, 431 glyphs each. The watch gives the date in its own language, and a letter that is not in the font is drawn as nothing, so the fonts must cover every language the watch can be set to. The big font shows the time, so it holds only the digits and a colon.

JetBrains Mono is licensed under the SIL Open Font License 1.1. See docs/OFL.txt.

Layout grid

Every layout is drawn on a 390 x 390 grid and scaled to the screen with Draw.p(). Each screen size has its own font set in resources-round-<size>x<size>/fonts.
