• Chopard has marked 50 years of its free-moving Happy Diamonds, made since 1976, with two Heritage watches reinterpreting the collection's 1970s design.
• Both have a cushion-shaped 18-carat ethical yellow gold case and a black onyx dial, with 21 moving diamonds on the 34mm and nine on the 24mm.
• The hand-wound 34mm costs A$74,400 or US$48,400 and the quartz 24mm A$36,900 or US$24,000, in very limited quantities.

Most of us who grew up on tool watches spent years quietly filing Happy Diamonds under someone else's hobby. It was the watch in the jeweller's window with the diamonds rattling around the dial, lovely, a little flashy, clearly not for us. I held that view for a long time, and it is only in the last few years, as smaller gold watches and a bit of sparkle stopped being embarrassing for anyone, that I have started to see what Chopard actually did. Free diamonds, moving under glass, were a genuinely odd and brave idea, and Chopard has been making them since 1976. Fifty years on, it has gone back to the shape of the originals with the Chopard Happy Diamonds Heritage.

A cushion case and a black stone dial

There are two watches, and both use a cushion-shaped case in 18-carat ethical yellow gold with a dial of black onyx, on both the inner and outer rings. That black is the whole trick. Against onyx, polished like a piano lid, gold and diamonds stop looking like decoration and start looking like light moving on dark water, which is roughly the image Chopard reaches for itself when it compares the diamonds to sunlight on a waterfall.

The larger model is 34mm across and 8.53mm thick, and it is the one I keep coming back to. The smaller is 24mm and 6.72mm thick. Both have a sapphire crystal on the front, an 18-carat yellow gold crown and a water resistance of 30 metres, which covers washing your hands and very little else.

Twenty-one diamonds, loose between two crystals

On the 34mm model, 21 diamonds move freely across the dial, set between two sapphire crystals so they can slide and settle as the wrist moves. Chopard lists the total diamond weight at 1.05 carats. The 24mm watch carries nine moving diamonds.

The idea is still charming in a way that photographs struggle with. A still image shows a neat row of stones collected at six o'clock. In motion they gather and scatter, and the dial never quite looks the same twice. I would rather that than a fixed bezel of pavé, because the movement is the point; a Happy Diamonds that stayed still would just be a diamond watch.

Hand-wound in the larger size

The two watches split on what drives them, and it is the most important difference between them. The 24mm model uses a quartz movement, which makes sense in a case that small and keeps it light and slim. The 34mm model runs Chopard's own hand-wound calibre 10.01-C, a small, thin movement at 2.90mm tall, with 101 parts and 19 jewels, beating at 3Hz, 21,600 vibrations per hour, and running for about 45 hours.

That reserve means winding it most mornings, which I would count as a pleasure rather than a chore on a watch like this. The movement shows hours and minutes only, with nothing to distract from the diamonds, and Chopard has given it nickel silver bridges and mainplate with a grained motif on the bridges, a flat balance spring and a three-spoke balance.

Turn it over

The 34mm has a sapphire caseback, so the 10.01-C is on show, and in Chopard's photograph the movement sits inside a black surround carrying the Happy Diamonds name in gold. It is a small echo of the front of the watch, and a reminder that the larger model is the one with something mechanical to show off.

Alligator, a gold buckle, and a note on sizing

Both are fitted with a black alligator leather strap and an 18-carat yellow gold pin buckle, although Chopard notes that online orders are delivered on calf leather instead because of shipping restrictions on alligator. Plain black leather is the right call against the onyx, and it keeps the watch from tipping over into jewellery.

Chopard describes the 34mm model as unisex, and I think that label matters more than it seems. A 34mm gold cushion case with a hand-wound movement is, frankly, a very handsome dress watch for anyone. Those of us who spent years wearing 42mm steel divers to dinner might have been missing something.

The Chopard Happy Diamonds Heritage pricing and availability

Both models are listed in the Happy Diamonds collection on Chopard's Australian site, with boutique enquiries taken through its Melbourne and Sydney boutiques among others. Chopard says the pieces are available in very limited quantities and asks buyers to register their interest.

Price: A$74,400, US$48,400, £39,000, €46,000 (34mm, hand-wound, reference 202299-0001); A$36,900, US$24,000, £19,400, €22,800 (24mm, quartz, reference 203787-0001).

What fifty years of loose diamonds tells us

The obvious objection is the price. A$74,400 is serious money for a time-only watch, and nobody is going to pretend otherwise. But what this pair shows is how much of the watch world has moved towards Chopard rather than the other way round. Small gold cases, stone dials and hand-wound movements are the things enthusiasts now ask for by name. Chopard has simply been doing a version of it since 1976, and has finally made one that the rest of us can see ourselves wearing.
