SKULL DIAL is a theme optimization app designed for Android-based wearable devices. It offers a collection of skull-themed designs, featuring intricate skull outlines integrated into various watch face layouts. Compatible with a wide range of popular watch brands, these designs blend seamlessly into the watch’s structural elements, lending a dark, edgy aesthetic to your timepiece. The app also includes a power reserve indicator, allowing you to monitor your watch's energy levels. With SKULL DIAL, you can easily bring a striking skull motif to your watch screen, with quick and simple settings for easy customization.

Features
Mechanical Jaw/Smiling Effect: Certain models (such as the Bell & Ross "Skull" collection) feature a mechanical jaw mechanism that causes the lower jaw to open and close as the watch is wound.
Fluidic Displays and Ocular Indicators: Timepieces like the HYT Skull utilize a fluid-filled capillary tube to outline the skull, with the two eye sockets serving as a power reserve indicator and a small-seconds sub-dial, respectively.
High-End Complications: Prestigious brands—including Richard Mille (e.g., the RM 052), Roger Dubuis, and Hublot—integrate the skull motif directly into the bridges of a tourbillon movement.

Highlights
Employs a fluid-filled glass capillary shaped to trace an eight-bend skull outline to indicate the hours.
Displays the power reserve indicator in one eye and constant seconds in a rotating disc in the other.
The Skull Vida edition incorporates a unique dial crafted from ancient Siberian mammoth ivory.

Tips
Anchor to fixed markers first: Locate applied indices, printed chapter rings, or lume dots at the 12, 3, 6, and 9 positions before tracking the hands.
Distinguish the hands: The hour hand is shorter, thicker, and sits closest to the movement surface, while the minute hand stretches longer over the top of the stack.
Check the contrast: Ensure your handset (e.g., silver, rose gold, or luminescent hands) contrasts sharply against the skull or gearwork background so it doesn't get lost.

Summarize
Presents dial perfect for those who want to decorate their timepieces with something novel, stylish and dark. We are dealing here with a whole collection of skulls, executed mainly in black and white with occasional splashes of other colors. For this reason, it is best they look on AMOLED, but nothing prevents you to use them on the clock with some other type of screen.
