Description
Rado's True Square Open Heart is a compact square watch for women who prefer a modern, sculpted look. It pairs a black dial with a black bracelet, giving the whole piece a uniform, dark appearance on the wrist.
The case measures 29.2 mm across and 8.1 mm thick, and is made from high-tech ceramic and titanium with a PVD finish. A quartz movement drives the analog display, and a sapphire crystal protects the dial. Water resistance is rated at 5 bar, or 50 m, which covers splashes and everyday handwashing.
The bracelet combines high-tech ceramic and titanium and closes with a foldover clasp. At 68 g it is light enough for daily wear, and the square silhouette sets it apart from the round cases that dominate the category. It suits office, evening and casual use alike.
Frequently Asked Questions
Can I wear the True Square Open Heart in the shower?
It is rated for 5 bar, or 50 m, so showers are technically within range. Hot water and steam can wear down seals over time, though, so for the Rado True Square Open Heart a quick rinse is fine but regular long showers are best avoided. Swimming is not recommended.
Is it suitable for daily wear at the office?
Yes in practice, because the Rado True Square Open Heart weighs only 68 g and is 8.1 mm thick, so it slides under a cuff easily. The ceramic and titanium bracelet resists scratches well, and the sapphire crystal keeps the dial clear through a normal working day.
Will a 29.2 mm square case fit my wrist?
The case is compact, so it generally suits small to medium wrists best. Because the shape is square rather than round, it can look a little larger than the number suggests. If your wrist is on the larger side, try it on first, as it will sit smaller than most modern watches.
How does it differ from a mechanical dress watch?
Instead of an automatic movement, it runs on a quartz movement, so it keeps steady time without winding and needs far less servicing. A mechanical dress watch offers more craft and a visible mechanism, while the Rado is lighter, more scratch-resistant and easier to live with day to day.
How often does the battery need changing?
Quartz watches like this one generally need a new battery every two to three years, depending on use. A watchmaker or service center should do the swap and check the seals, which keeps the 50 m water resistance dependable over the long term.
Who is this watch suitable for?
It is aimed at women who want a small, light and distinctive watch with a modern look. The True Square Open Heart suits people who value scratch resistance and comfort on the wrist over sporty features, and it works well for office, evening or gifting.
Editor's take
Among Rado's catalog, the True Square line is the brand's answer to people who want a ceramic watch that does not look like a sports piece. This Open Heart version is a small, square, black-on-black watch built around a quartz movement, and it is clearly aimed at women who want a compact, low-maintenance daily piece.
The materials are the real story. The case and bracelet use high-tech ceramic together with titanium, finished in PVD, which keeps the watch at 68 g despite its solid look. A sapphire crystal covers the dial, so scratches are less of a worry in daily use than with mineral glass.
The limits are practical ones. At 50 m water resistance it handles splashes and rain, but it is not a swimming watch, and the 29.2 mm square case is small enough that wearers with larger wrists may find it tight. Anyone wanting a mechanical movement will also need to look elsewhere, as this is a battery-powered watch.
It suits someone after a distinctive, light, scratch-resistant watch for office and evening wear. For a similar budget, a round automatic dress watch offers more mechanical interest, while this one wins on durability and wrist comfort. The foldover clasp keeps the bracelet secure and tidy.
