Moonphase Elegant Gold Analog
· v1.0.0
About
A dress watch face with an astronomical moon phase. Gold on true black.
Six finishes, and a dial drawn the way a fine watch is finished.
THE MOON IS COMPUTED, NOT GUESSED
Most moon phase faces run on a fixed 29.5-day cycle. The moon does not: its
orbit is an ellipse, and the phase runs ahead of the average, then behind it.
This face carries the correction terms. Checked against ten real eclipses
between 2017 and 2025 — a solar eclipse can only happen at new moon, a lunar
eclipse only at full moon — it lands within twenty minutes every time.
The terminator is drawn as a half ellipse, which is the shape a shadow actually
takes on a sphere lit from the side. Not a black disc sliding across a circle.
Southern hemisphere? One setting mirrors the crescent, so it matches the moon
you actually see. Swiss watches never bothered.
DRAWN THE WAY A DIAL IS FINISHED
• Sunburst guilloche — a hundred and forty-four engraved rays that give the dial
its material. A flat black face has none
• Applied indices, faceted: one half lit, one half in shadow, split by a dark
edge, the way polished metal is cut
• Roman numerals at the quarters
• Faceted leaf hands
• A minute track with no rings, so nothing competes with the engraving
The dial is drawn as geometry, not assembled from images — only the Roman
numerals come from a font, and it weighs sixty-eight pixels by forty-five. The
face stays sharp on every screen from 360 to 454 pixels. Nothing is upscaled.
SIX FINISHES
Gold, silver, salmon, steel blue, emerald, copper. All on true black, which on
an AMOLED screen means pixels physically switched off.
ASKS NOTHING OF YOUR WATCH
No permissions. No sensors read. No phone connection required. It reads the
clock, and computes the rest.
MAKE IT YOURS
Guilloche, Roman numerals, minute track, moon phase and date window all switch
off independently. Turn a window off and its numeral comes back — the dial
never leaves a hole.

I read every review and I reply. If something bothers you — a colour, a
proportion, an option you wish existed — say so and I will look at it.
