From raw steel to open dial

At the heart of every watch is the 2801 automatic movement, built with 66 precision-crafted components and 17 synthetic jewels to minimize friction and enhance durability. With a 48-hour power reserve and a 21,600 vph beat rate, it offers dependable performance day after day.
Why open heart
Most watches hide their mechanics behind a solid dial. Volcano cuts a window straight through it, so the beating balance wheel is on permanent display — proof the movement is genuinely mechanical, not quartz.
Cut with precision
The aperture is milled directly into the dial plate and finished by hand so the edge sits clean against the moving parts beneath it.
Framed in steel
A polished sub-ring borders the opening, giving the exposed mechanism a finished, deliberate look rather than a raw cutaway.
Always in motion
The balance wheel oscillates at 21,600 vibrations per hour, so there's always something moving in the window — a small, constant reminder the watch is alive on your wrist.
