Bulova Maquina Automatic Skeleton 98A321

On this Maquina, the green patterned dial is only part of the show. A large opening at its center reveals the moving mechanism underneath, framed by black bridges and silver-tone markers. Gunmetal steel around the dial keeps the palette dark, so the green and the exposed movement command the attention.

Why this watch stands out

The 40mm case has a curved sapphire crystal and a matching gunmetal-tone bracelet, with black details continuing across the bezel and dial. It is a more compact take on the Maquina’s industrial design, but it does not soften the collection’s angular look. The movement is visible again through the transparent caseback.

What does all of this do?

The exposed mechanism is a working automatic movement, not a decorative insert. As you wear the watch, a moving weight winds its mainspring; the stored energy then drives the hands. Its power reserve is approximately 42 hours when fully wound. The opening in the dial lets you see part of that mechanical process without turning the watch over.

Our take

Some skeleton watches ask you to choose between reading the time and looking at the movement. Here, the green dial and bright hour markers provide a frame for both. The dark bracelet makes the exposed mechanics feel like the centerpiece rather than an extra feature.
