Description
The Rado True Round Open Heart is a unisex automatic watch from the True Round collection. Its black skeleton dial and fully ceramic construction suit anyone who wants a modern, low-maintenance look with a visible mechanical character.
The watch uses a Swiss automatic movement inside a 40mm ceramic case, paired with a sapphire crystal. The bracelet is also ceramic in black and closes with a foldover clasp. Water resistance is rated at 50 m, which covers splashes and brief exposure to water.
The open heart dial is the feature that stands out, letting you see part of the mechanism at work. At 10.4 mm thick and 110.7 g, it has a solid presence on the wrist, and the lug width of 21 mm is a useful detail for those who think about proportions. It works as an everyday watch for office and evening wear.
Frequently Asked Questions
Can I wear the Rado True Round Open Heart in the shower or pool?
The watch is rated to 50 m, which generally handles splashes, hand washing and rain. A shower is best avoided because hot steam and soap can wear on seals over time. For swimming, a watch with a higher rating is a safer alternative.
Is it tough enough for daily wear and sport?
With a ceramic case and bracelet plus a sapphire crystal, the Rado True Round Open Heart resists scratches well in daily use. It is not built for impact sport, since ceramic can chip on a hard knock. It suits office, travel and evening wear.
How does it fit on my wrist at 40mm?
The case is 40mm across and 10.4 mm thick, with a 21 mm lug width, so it suits most average wrists. It weighs 110.7 g thanks to the ceramic bracelet, so who it suits is mainly those who like a solid feel on the wrist.
How is it different from a steel automatic watch?
Compared with a steel automatic, the ceramic case and bracelet are far more scratch resistant and keep their black finish. The trade-off is weight and the chipping risk. A steel alternative is lighter and easier to adjust.
Does it need a battery or winding?
It uses a Swiss automatic movement, so there is no battery. Wrist motion winds it, and it keeps running while worn regularly. Service is best done by an authorised service centre every few years, since the mechanism is visible and benefits from regular oiling.
Can I resize the bracelet myself?
The black ceramic bracelet closes with a foldover clasp. Ceramic links are hard to work with, so resizing is best left to a watchmaker or authorised Rado service centre rather than done at home with standard tools.
Editor's take
Rado built its reputation on scratch-resistant materials, and the True Round Open Heart carries that tradition into a ceramic case and bracelet in black. It is aimed at unisex wearers who want a modern dress-leaning piece with a visible mechanical side.
The core of the watch is its Swiss automatic movement, shown through the open heart dial. Over it sits a sapphire crystal, which pairs well with ceramic since both resist scratches in daily wear. The 40mm diameter and 21 mm lug width keep the proportions balanced.
The main trade-off is water resistance. At 50 m, the watch handles splashes and hand washing, but it is not meant for swimming or water sports. At 10.4 mm thick and 110.7 g, the all-ceramic build is also noticeably heavy compared with a steel watch of similar size.
It suits someone who wants a low-maintenance, scratch-resistant automatic for office and evening use. For swimming, a steel diver with a higher rating is the better alternative, while those who prefer lighter wear could consider a steel-bracelet automatic with a foldover clasp.
