  • CDs are getting the audiophile treatment again, sitting somewhere between the ritual of vinyl and the convenience of digital music.
  • Top-loading design brings back the ritual of physical music.
  • Rigid aluminum construction and a low-vibration SUOS drive help reduce jitter and unwanted noise.
  • It’s Pro-Ject’s first RS-series CD player with an integrated DAC, pairing a PCM1796 converter with a balanced dual-E88CC tube output stage.
  • At US$2,799, this is CD playback turned into a luxury purchase.

The compact disc was once supposed to be the future of music, until streaming arrived and turned shelves full of CDs into something many of us packed away years ago. Now, with physical music enjoying something of a second life, Pro-Ject is making a rather expensive argument for digging those old discs back out. The new CD Box RS2 Tube takes the familiar CD player and gives it the full audiophile treatment, combining a dedicated top-loading mechanism, high-end DAC, balanced circuitry and a pair of vacuum tubes inside an aluminum body.

At US$2,799, this obviously isn’t the machine you buy because you’ve found a box of old CDs in the garage and want to hear them again. The CD Box RS2 Tube sits in Pro-Ject’s top-range RS2 line and is aimed squarely at listeners who still see physical music as part of the experience, right down to placing the disc onto the exposed top-loading mechanism and securing it with a magnetic clamp before pressing play.

That top-loading mechanism isn’t there purely for theatre. Pro-Ject uses a SUOS DM-3381 Red Book CD-DA drive with its BlueTiger CD-88 servo system, developed specifically around conventional audio CDs rather than relying on a multipurpose optical drive. A magnetic clamp holds the disc in place, while the player’s gravity design and central mass point are intended to keep unwanted vibration under control.

The bigger difference comes after the disc has been read. Unlike a standalone CD transport, the RS2 Tube has its own Texas Instruments PCM1796 DAC, used in a fully differential configuration before feeding a balanced analogue output stage built around two E88CC vacuum tubes. Pro-Ject says those tubes are intended to bring warmth, fluidity and a more natural harmonic character to digital playback, with listeners able to connect through either balanced XLR or conventional RCA outputs.

It’s an interesting combination because CDs have spent decades being associated with convenience and digital precision, while glowing vacuum tubes belong to a much more romantic corner of the hi-fi world. Putting the two together feels almost deliberately contradictory, but that’s also what makes the CD Box RS2 Tube interesting: Pro-Ject isn’t reinventing the compact disc so much as treating it with the sort of attention normally reserved for expensive turntables and analogue systems.

The physical construction follows the same philosophy, with full aluminum casework, a large front LCD that can display track, time, and CD-Text information when available, and even an aluminum remote control rather than the lightweight plastic controller usually thrown into the box. At only 206mm wide but weighing around 3.2kg, it’s also considerably more substantial than its compact footprint might suggest.

There are some very deliberate limitations, though. This is a Red Book CD-DA player, not a do-everything digital source designed for SACDs, Blu-rays or a library of high-resolution files, which makes that US$2,799 asking price even more interesting. You’re paying for a machine built around doing one increasingly old-fashioned thing exceptionally seriously, rather than another box promising to handle every format imaginable.

And perhaps that’s really the appeal. Streaming gives you millions of songs almost instantly, but there’s still something satisfying about choosing an album from a shelf, physically loading it and listening without an app endlessly suggesting what should come next. CDs may not have quite the same ritual as lowering a stylus onto vinyl, but an aluminum top-loader with a magnetic clamp and two glowing vacuum tubes certainly gives them a little more ceremony.

At US$2,799, nobody needs a CD Box RS2 Tube simply to hear a compact disc, and there are obviously much cheaper ways to play the collection you already own. But necessity isn’t really what products like this are about; Pro-Ject has taken one of the most ordinary physical music formats of the past four decades and treated it like a genuinely high-end source component.

Breguet Lets Time Take Flight with Its First-Ever Flying Tourbillon in the Sidéral 7255

  • Breguet continues its 250th-anniversary celebrations with the unveiling of the Classique Tourbillon Sidéral 7255, a highlight in the maison’s commemorative collection.
  • This model marks a historic milestone as the first Breguet creation to feature a flying tourbillon, an evolution of the complication that enhances its weightless, celestial aesthetic.
  • Launched on 26 June 2025, the timepiece intentionally mirrors the date Abraham-Louis Breguet secured the tourbillon patent in 1801, creating a symbolic bridge across centuries.
  • Limited to just 50 pieces, this the Classique Tourbillon Sidéral 7255 stands as one of the first creations in Breguet featuring a “flying tourbillon”.

Marking a moment that feels both cosmic and deeply historical, the Classique Tourbillon Sidéral 7255 arrives as Breguet approaches its 250th anniversary — a milestone tied back to the maison’s founding in 1775. Rather than simply revisiting its heritage, Breguet uses this occasion to unveil a timepiece that pushes its legacy: the brand’s first-ever flying tourbillon, a mechanism long associated with its identity yet never before realized in this form. Years of quiet development have shaped this new construction, giving the tourbillon an almost weightless presence, as if it were suspended in orbit.

The release date adds another layer of significance. Presented on 26 June 2025, the Sidéral 7255 arrives exactly 224 years after Abraham-Louis Breguet patented the original tourbillon, a moment that reshaped the future of mechanical watchmaking. By choosing this date, the maison doesn’t just honour its founder — it extends his work into a new chapter, blending innovation with reverence in a way only Breguet can achieve.

This isn’t your ordinary dial; Breguet introduces something entirely new to the brand’s collection. For the first time, Breguet uses aventurine enamel, a material chosen for its celestial sparkle and its connection to the astronomical studies that once fascinated Abraham-Louis Breguet. Its deep blue surface glows with a star-like brilliance, creating a cosmic backdrop for the newly liberated tourbillon. Together, the airborne mechanism and the night-sky enamel transform this timepiece into more than just a commemorative piece — it becomes a poetic bridge between centuries of horological mastery and the future Breguet continues to shape.

The name “Sidéral” is no poetic coincidence. In astronomical terms, it refers to measurements guided not by the sun but by the fixed constellations — a nod to timekeeping rooted in the stars rather than the day’s light. Breguet intentionally embraces that celestial meaning, weaving the idea of cosmic precision throughout the Sidéral 7255. It’s a reminder that long before Abraham-Louis Breguet reshaped horology, humanity looked to the heavens to define the passing of time, trusting the constancy of the night sky.

That astronomical thread persists through the tourbillon itself. While the complication is now celebrated for its mechanical elegance, its roots intersect with scientific thought from centuries earlier. In the 17th century, Blaise Pascal expanded on the word “tourbillon,” describing it as a rotating material system — a concept he connected to the motion of planets. That philosophical link has never truly faded. Even today, the tourbillon maintains a subtle connection to celestial mechanics, evolving in shape but still echoing the rotational harmony observed above us.

Which brings us to the highlight of this anniversary timepiece: the flying tourbillon. Unlike the traditional design supported by an upper bridge, this version is mounted without visible anchoring from above, creating the illusion that the mechanism is floating freely within its cage. On the Sidéral 7255, it hovers over the dial with a purposeful lightness — a mechanical constellation of its own, rotating in space as if unaffected by gravity. It’s a stunning visual, and a fitting tribute to both the astronomical origins of the tourbillon and Breguet’s unwavering pursuit of refinement.

The flying tourbillon inside the Sidéral 7255 isn’t just visually striking — its construction represents a meaningful shift for the maison. Breguet chose to eliminate the traditional upper pivot entirely, building the mechanism so that all its stability comes from the base. This foundation is formed from sapphire glass treated with an anti-reflective coating, allowing the point of interaction between the gears and the carriage to nearly disappear. That architectural decision creates the uncanny illusion that the tourbillon is drifting freely above the dial, untouched by physical support — a sensation that instantly sets this timepiece apart. For Breguet, this is more than a refinement; it’s a moment of evolution, something CEO Gregory Kissling acknowledges as a first in the brand’s long lineage.

“It is, quite simply, the very first time in Breguet’s history that a flying tourbillon is being introduced. A beautiful way to celebrate its 224th anniversary,” Kissling said. “And the tourbillon model we chose to reinterpret is no ordinary one: among the tourbillon movements in Breguet’s archives, it is the one used in the very first Breguet tourbillon wristwatch, unveiled in 1990 under reference 3350.

“Invented by Abraham-Louis Breguet in 1801, the tourbillon remains one of the most complex complications in watchmaking. Its mastery embodies the technical excellence to which the House of Breguet has remained faithful for more than two centuries,” the Breguet CEO continued. “The Classique Tourbillon Sidéral 7255 thus pays homage to that iconic timepiece and to the master’s invention. I would even go so far as to say that this creation is an ode to the tourbillon itself, where time indication is almost secondary…”

The spirit of Abraham-Louis Breguet continues to resonate through every modern creation bearing his name, and the Sidéral 7255 might be the clearest example yet. More than 200 years after the original tourbillon patent, the maison is still refining his quest for accuracy and resilience. The “mysterious” flying tourbillon shown here wasn’t something Breguet hurried into—it’s the result of meticulous development over many years, pushed until the floating effect reached the level of perfection the brand demands.

What surrounds that airborne mechanism is equally extraordinary. The Sidéral 7255 is crafted from a selection of materials chosen not only for beauty but also for significance: 18K Breguet gold components, a hand-guilloché caseback, and that captivating aventurine enamel dial whose celestial shimmer links the entire design to astronomy. Every element works in harmony, giving the timepiece both visual poetry and technical credibility.

Exclusivity defines the story. With only 50 examples to be produced and a price around USD $226,000, this isn’t just a watch — it’s a statement piece for those who appreciate its craftsmanship. Some creations are hard to put into words, much like the night sky the dial hints at. The Sidéral 7255 fits that description. If you come across one… don’t forget your favourite magazine editor.
