Triangular Layout

At the apex of this geometric composition sits a prominent large date display, while the triangle's base houses the weekday and month indicators in perfect balance, creating an unusual yet harmonious layout that feels both fresh and timeless.

Squircle Dial

The main timekeeping is displayed on a distinctive "squircle" dial—a mix of square and circular shapes—featuring traditional hours, minutes, and seconds hands alongside beautifully applied hour markers.

Custom Typography

Every numeral features custom fonts I designed and applied to each dial for clean visual harmony, ensuring that these complex complications enhance rather than compromise the fundamental time display.

Hidden Technology

Ultra-precise stepper motors and WiFi connectivity remain invisible, preserving the classical aesthetic while enabling modern functionality including perpetual calendar with automatic daylight saving time adjustment.

Interactive Crown

The clickable digital crown makes setup and exploring all the features fun, allowing intuitive navigation through the timepiece's various functions.

Premium Materials

Each timepiece combines quality materials—brass, steel, walnut wood—hand-assembled in my USA garage workshop with individual attention to detail and careful finishing both inside and outside.
