Description
The Rado True Square Automatic Skeleton is a unisex Swiss watch built around a distinctive square case. It suits wearers who want a modern, design-led piece with a visible mechanical heart rather than a conventional round dress watch.
The case measures 38 mm across and 9.7 mm thick, with 20 mm lugs. A Swiss automatic movement is seen through the skeleton face, and a sapphire crystal protects the blue dial. Water resistance is rated at 50 m, which covers splashes and everyday handwashing.
The blue rubber strap closes with a foldover clasp and matches the blue dial. The sizing is moderate enough to work on a range of wrists, and the skeleton face gives the square shape a lively, technical look for daily wear.
Frequently Asked Questions
Can I wear the Rado True Square in the shower or pool?
It is rated to 50 m, which covers rain, splashes and handwashing. Showers and swimming are better avoided, since hot water and pressure from movement can stress the seals. For regular swimming, a dedicated diver is the more suitable alternative to this daily watch.
Will a 38 mm square case suit a smaller wrist?
At 38 mm wide and 9.7 mm thick, the True Square sits fairly compact and works on a wide range of wrists, including smaller ones. The square shape can look slightly larger than a round case of equal size, so it is worth trying on in person if your wrist is slim.
What movement does it use and do I need to wind it?
It uses a Swiss automatic movement, visible through the skeleton face. It winds itself with wrist motion during daily wear, so regular use keeps it running. If it sits unworn for a few days, a gentle manual wind or a short wear will restart it.
Is the blue rubber strap easy to swap for something else?
The lugs are 20 mm wide, so most 20 mm straps fit, though the square case suits straps with a straight, even taper best. The foldover clasp is part of the original strap, so changing to a standard buckle strap changes how the watch fastens.
How does it differ from a round Swiss automatic at a similar level?
The main differences are the square case, the skeleton face and the sapphire crystal. A round dress automatic usually reads more easily and feels more traditional, while this model offers a modern look and a visible movement, which suits wearers who value design.
How often does the battery or service need attention?
There is no battery, as it is an automatic. Service is usually considered every five years or so, when the movement is cleaned and lubricated and the seals are checked, which also helps keep the 50 m water resistance dependable.
Editor's take
Rado's True Square line takes the brand's long habit of design experimentation and gives it a clean geometric form. This version pairs a Swiss automatic movement with a skeleton face, aimed at unisex wearers who want a mechanical watch that looks different from the usual round field of rivals.
The 38 mm square case is only 9.7 mm thick, which keeps it neat under a cuff. A sapphire crystal guards the blue dial, a sensible choice because scratch resistance matters on a case with flat, exposed planes. The 20 mm lug width and the blue rubber strap with a foldover clasp give the watch a sporty, easy-wearing character.
The main compromise is 50 m water resistance. It handles rain and handwashing, but it is not a pool or sea watch, and the rubber strap invites exactly that kind of use. A skeleton face can also be busier to read than a plain dial, so quick time checks take a little more attention.
This suits someone who wants a design-forward automatic for daily wear and appreciates seeing the movement at work. For a plainer dial at a similar level, a conventional round Swiss automatic is the alternative, whilst water sport users should look at a dedicated diver.
