Rado’s DiaStar has never been a quiet watch, and that’s exactly the point.
The brand’s latest DiaStar Original Skeleton limited editions lean into that personality with three saturated summer tones, giving the openworked model a brighter and more playful edge without losing the space-age shape that made the watch recognisable in the first place.
Blue, green and red versions join the collection, each produced in limited numbers and each built around the same compact case, faceted crystal and automatic skeleton movement.
At a glance
- Rado has introduced three colourful DiaStar Original Skeleton limited editions in blue, green and red.
- Each model uses a 38mm by 45mm case with a Ceramos bezel, faceted sapphire crystal and automatic R808 movement.
- Production is limited to 555 pieces per colour, with prices from EUR 2,500.
A helmet case with a brighter mood
First launched in 1962, the DiaStar was positioned by Rado as the world’s first scratch-resistant watch, but its lasting power has as much to do with shape as material.
The oval, helmet-like case still looks unusual decades later, which makes it well suited to Rado’s current push into openworked dials and stronger colour.
These new DiaStar Original Skeleton editions measure 38mm wide, 45mm long and 11.9mm thick, keeping the watch compact while preserving its broad, architectural presence on the wrist.
The defining convex bezel is made from Ceramos, Rado’s proprietary composite designed to combine ceramic hardness with a metallic sheen.
On the blue and red editions, that bezel is polished with a radially brushed surface and paired with stainless steel case components.
The green edition takes a warmer route with a yellow-gold-coloured PVD-coated Ceramos bezel and matching PVD-coated steel elements.
A faceted sapphire crystal sits above the dial, echoing one of the DiaStar’s long-running visual signatures, while a sapphire display back opens the rear view to the movement.
Water resistance is rated to 100 metres, which gives the trio a practical footing beyond its deliberately expressive styling.
Blue, green and red around an openworked calibre
The skeleton architecture gives each watch a mechanical centre stage, but the colour treatment changes the mood considerably.
The blue model uses a blue dial ring and matching rubber strap, with rhodium-coloured hands and floating indices accented by yellow Super-LumiNova.
The green edition pairs its green dial and strap with gold-coloured hands and markers, then adds red luminous material for a more unexpected contrast.
The red model is the most vivid of the three, combining a red dial ring and strap with rhodium-coloured hands and indices filled with green Super-LumiNova.
All three retain the floating index layout and Rado’s moving anchor logo, details that help keep the design recognisably DiaStar rather than simply another skeleton watch in a bright case.
The colour-matched rubber straps are fitted with Rado’s EasyClip system, allowing quick strap changes without tools.
Each watch is finished with a stainless steel pin buckle matched to the case treatment.
The R808 movement keeps the focus practical
Inside all three models is the automatic Rado calibre R808, a movement used across recent DiaStar Skeleton references.
It runs at 21,600 vibrations per hour, uses 25 jewels and incorporates a Nivachron hairspring.
The 80-hour power reserve is a useful detail for a modern automatic watch, particularly for owners who rotate several pieces through the week.
Rado also notes that the calibre is adjusted beyond standard requirements, with regulation carried out in up to five positions to support improved accuracy.
The display back suits the watch’s character, because the DiaStar Original Skeleton is not trying to hide its mechanical theatre behind a conventional dial.

These limited editions work because they don’t try to soften the DiaStar’s eccentricity.
Instead, Rado has amplified the watch’s futurist profile with colour, open mechanics and tactile materials, creating a trio aimed at collectors who prefer their summer watch with a little more character than the usual nautical dial change.
