The Bambino Open Heart puts Orient's F6724 balance wheel on display through a heart-shaped aperture cut into an otherwise conservative dial. It is one of the most affordable ways to own a genuine in-house automatic with a finishing detail that would cost three times the price anywhere else. Clean proportions, honest specs, real movement credentials.
Orient has made its own movements in Japan since 1950, and the Bambino line has been the entry point to that tradition for decades. The V5 generation, introduced around 2018, refined the case proportions to 40mm and updated the dial finishing across the lineup. The Open Heart variant was added to give collectors a mechanical spectacle without abandoning the Bambino's dress-watch restraint.
The heart-shaped aperture is a deliberate nod to high horology's skeleton tradition, executed at a price that makes it accessible rather than aspirational. The F6724 inside is the same family of movement Orient has been developing and manufacturing in-house at its Higashimurayama factory for years.
The heart aperture adds visual interest but also collects dust and lint more readily than a closed dial; inspect used examples carefully under a loupe. Some buyers find the aperture placement slightly off-center relative to the dial symmetry, which is a matter of taste but worth seeing in person before buying. The F6724 hacks but does not hand-wind, which is a minor inconvenience if the watch has sat unworn and the power reserve is depleted.
Water resistance is a modest 30m, so this is a dress watch only; do not wear it near water. Lume on the Open Heart variants is minimal and largely decorative given the dress context.
