Stepping up in Chopard's range
The Happy Sport was born in 1993 from a deliberate act of rule-breaking: Chopard set diamonds free between two sapphire crystals rather than fixing them in a setting, and paired them with steel rather than gold. That decision founded one of the few modern watch designs with a genuinely original mechanical idea at its centre. This version takes that idea further, shaping the floating elements as a sun, moon and stars above a guilloché blue dial — making the celestial theme legible in silhouette rather than just implied by colour. At 36mm the proportions suit a dressed wrist without overwhelming it, and the exhibition caseback means the movement is part of the watch on both sides. The blue alligator strap coordinates closely enough with the dial to read as a considered pairing. The date sits between four and five o'clock, tucked into the chapter ring in a way that does not compete with the floating diamonds, which is where the eye naturally goes first and stays.

Frequently asked questions, and things you should know about this watch
Can I swim with it?
No. At 30m it will survive rain and handwashing, but not submersion of any kind.
Will the glass scratch?
Unlikely. Sapphire is second only to diamond in hardness and shrugs off everyday marking.
Does it need a battery?
No. It is automatic — the motion of your wrist winds it, and there is no cell to replace.
How long does it run for when it's not worn?
About 42 hours fully wound — enough to survive a night off the wrist, but not a full weekend.
Is it a men's or women's watch?
Listed as women's, though at 36mm it sits in the range that suits anyone.
Cheapest place to buy
Goldsmiths is the only UK retailer we track stocking this reference, so there is nothing to compare it against today.
