Watchgrid: Celestial Moonphase

Solidcrafts

About this app

Master Swiss astronomical horology on your wrist. Watchgrid Celestial Moonphase unites grand complications with contemporary elegance for Wear OS 5, featuring a live astronomical moonphase that dynamically tracks the real lunar cycle across all 8 phases, dedicated day-of-week and date subdials, and fluid 15 Hz continuous sweeping hands.

Built strictly on Google and Samsung's native Watch Face Format (WFF), Celestial Moonphase runs purely as declarative hardware-rendered graphics—delivering buttery-smooth mechanical sweep motion with superior battery efficiency.

Key Features:
• Live Astronomical Moonphase: Real-time lunar cycle synchronization dynamically rendering 8 photorealistic 3D moon phases with authentic lunar maria, crater reliefs, and atmospheric corona.
• Grand Dual-Subdial Calendar: 12 o'clock day-of-week pointer subdial and 6 o'clock date pointer subdial surrounding the starry night aperture.
• 4 Luxury Dial Themes: Onyx Black dégradé (Default), Deep Sapphire Blue sunburst, Emerald Green sunburst, and Sunburst Silver with flame-blued steel indices.
• 3D Faceted Alpha Hands & Slender Needle: Multi-faceted dauphine hands finished with dual-tone specular highlights and a default vibrant crimson red second hand.
• 15 Hz Continuous Mechanical Sweep: Fluid gliding second hand with zero battery stutter.
• Motion Styles: Select between 15 Hz smooth sweep, 1 Hz classic mechanical beat, or battery-preserving two-hand mode.
• Battery-Optimized Always-On Display (AOD): Deep OLED blacks with low-power luminous night hands, indices, and moon phase.
• Pure Watch Face Format: 100% compliant with Wear OS 5 and Google Play requirements. No background services, no companion app dependency.
