This is a retro-inspired watch face, which focuses on Steps and Heart Rate. The upper-left is the complication, which only shows what i call the "Glitch".

I have a paid version of this watch face (3-day free trial), with color customization, and the following complications:

1.) Glitch - random string of characters

2.) None - 5 full blocks: █████

3.) Time

4.) Date - configurable format

5.) Model - configurable format

6.) Time to Sunset or Sunrise

7.) Main Goal Progress

9.) Weather - outside temperature

9.) Altitude

10.) Ticker - custom scrolling text

Background:

I already have a really nice watch, and didn't want to not use it. The name comes from this watch, which uses small tritium vials for illumination. Tritium radioluminescence relies on the beta-decay of tritium, hence the name β-decay
