Rado Diastar Coupole

The Rado DiaStar Coupole: classic elegance and timeless refinement
The Rado DiaStar Coupole is one of the most popular collections among fans of the Swiss brand. Recognisable by its distinctive dome-shaped case — slightly domed, with an immediately pleasing visual appeal — this model has embodied Rado’s understated elegance and watchmaking expertise for decades.
An instantly recognisable signature design
The Coupole stands out thanks to the harmonious curve of its polished steel case, its domed sapphire crystal and its integrated link bracelet, which come together to form a remarkably fluid whole. The attention to detail in the finishes — mirror polishing, alternating matt and polished surfaces on the Jubilé versions — makes it a watch with character, suitable for both everyday wear and formal occasions.
Variations to suit every style
The DiaStar Coupole is available in several sizes and configurations:

21mm and 23mm: refined ladies’ models, available in silver, blue or two-tone gold/black
30mm and 32.5mm: versatile unisex models, with a classic or blue dial
35mm: a understated and elegant men’s model
Jubilee editions: a bracelet with alternating links and a polished finish, available in gold/steel, gold/black, or steel only — for a more formal and luxurious look
