There exists, within the vast and occasionally absurd universe of haute horlogerie, a certain hierarchy of complications, a pecking order determined less by visibility than by sheer, unforgiving difficulty. A perpetual calendar impresses. A chronograph charms. But a minute repeater, that rare mechanism which converts the time into sound, striking hours, quarters and minutes on demand through a series of hammers and gongs, remains one of watchmaking’s most jealously guarded arts, requiring not merely engineering precision but something closer to musical instinct. Pair that with a flying tourbillon, the visually spectacular device that counters gravity’s pull on a watch’s regulating organ while appearing to float, unsupported, within the movement, and you arrive at a combination so demanding that relatively few manufactures attempt it at all. Jacob & Co., a house never accused of excessive modesty, has not merely attempted it. For its 40th anniversary, the brand has brought back the very watch that first announced its arrival in this rarefied territory.
A Return to Where It All Began
The Palatial Flying Tourbillon Minute Repeater is not, strictly speaking, a new watch so much as a triumphant homecoming. First introduced in 2014, this was the piece that marked Jacob & Co.’s entry into minute repeater territory, the moment a brand best known for jewellery-grade extravagance proved it could also master watchmaking’s most acoustically demanding craft. Now, as the house marks its fortieth anniversary in 2026, it returns to that original milestone, rebuilding the watch around an entirely new calibre while preserving the essential design language that made the original so compelling.

The Case: Restrained Scale, Considerable Presence
Housing the mechanism is a 43mm round case crafted in 18K rose gold, finished with a broad polished bezel and sculpted lugs that lend the watch a markedly more elegant silhouette than the brand’s sportier Epic X collection. Despite accommodating two of watchmaking’s most space-hungry complications, the case measures a genuinely svelte 12.3mm in thickness, a detail Jacob & Co. attributes partly to its chief watchmaker’s own exacting insistence on restraint in proportion, even while mechanical ambition runs riot beneath the dial. Water resistance sits at a modest 30 metres, an entirely reasonable trade-off given that a minute repeater’s gongs depend on a case architecture built for resonance rather than submersion.
The Dial and Its Musical Architecture
The dial itself is rendered in a striking red mineral crystal, a warm, translucent filter that sits over the movement’s architecture without ever obscuring it, allowing the watch’s considerable mechanical theatre to remain the genuine star of the show. Through that red-tinted window, the one-minute flying tourbillon occupies its familiar position at 6 o’clock, completing a full rotation every sixty seconds, its hourglass-shaped balance wheel, a notably more demanding form to execute and poise than a conventional annular balance, visible in constant, mesmerising motion. The minute repeater mechanism itself employs two hammers paired with two cathedral gongs, gongs longer than conventional repeater gongs and wrapped around the movement’s circumference specifically to produce a richer, more resonant chime. Struck on demand, the watch sounds the hours in low tones, the quarters in alternating high and low tones, and the remaining minutes in high tones, the traditional grammar of minute repeater chiming rendered with genuine musicality.

The Caseback: Finishing on Full Display
Turn the watch over, and the sapphire caseback reveals the full architecture of the movement at work. Twin steel hammers, finely bevelled and finished in black polish, sit prominently visible, exactly as one would expect from a high-end repeater, while hand-polished Côtes de Genève striping runs across the bridges and the 18K rose gold oscillating weight completes the view. The overall finish leans toward a monochromatic anthracite restraint, a notably discreet choice from a brand that has built its reputation on showmanship, suggesting an emerging, more mature aesthetic register within Jacob & Co.’s broader collection.
The Movement: Caliber JCCM04
At the heart of the watch beats the manually wound Caliber JCCM04, an evolution of the original JCBM03 movement that powered the 2014 edition. Comprising 308 components and 29 jewels, the calibre operates at 21,600 vibrations per hour, or 3Hz, and delivers a genuinely generous 90-hour power reserve, impressive specification for a movement carrying this much mechanical complexity. The new calibre’s most significant technical advance lies in its newly engineered silent centrifugal governor, a component that controls the minute repeater’s striking cadence without generating the mechanical whirring noise conventional governors typically produce, allowing the chime itself to be heard with nothing to compete against it. Jacob & Co. has also redesigned the tourbillon cage itself for this edition, alongside broader improvements to the movement’s manufacturing and assembly, refinements that speak to more than a decade of accumulated expertise since the original model first proved the brand could compete in this exclusive category.
A Limited, Considered Return
The watch is presented on a red alligator strap secured with a matching rose gold pin buckle, a chromatic choice that ties the entire piece together with evident intention rather than mere flourish. True to the spirit of a genuine anniversary piece, the Palatial Flying Tourbillon Minute Repeater is limited to just 12 pieces, priced at USD 390,000 (or INR 3.8 crore), numbers that confirm this is less a product launch than a considered, deliberately scarce tribute to the complication that first proved Jacob & Co. belonged in horology’s most demanding conversations.
