Luxor Secondograph Seconde Mort – A Rare ‘Jumping Seconds’ Marvel with Chézard 7402
A remarkable confluence of technical rarity and vintage elegance, the Luxor Secondograph houses the elusive Chézard 7402 calibre—one of the few mechanical movements ever made to tick like a quartz. Known as seconde mort or jumping seconds, this rare function elevates the piece into the upper echelons of collectible horology, rivaling complications from the likes of Jaeger-LeCoultre, Omega, or even Rolex—but at a fraction of the price.
A Dial that Captures Time in Motion
Framing the dial is a special rotating seconds ring—an uncommon and delightful feature that enhances the visual impact of the jump-second complication. The crosshair dial, with its balanced symmetry and minimalist charm, is further punctuated by a date window at 3 o’clock, highlighted in red for a pop of vintage flair. All this sits beneath an original domed plexiglass crystal, complete with a charming cyclops magnifier over the date.
The hand-set remains era-appropriate, and the motion of the seconds hand—jumping cleanly once per second—is a mechanical spectacle in itself, designed to mimic the feel of a quartz but executed entirely through gears and levers.
Rosé Gold Elegance – Twisted Lugs and Bold Detail
Housed in a rosé gold plated 34mm case, the watch features beautifully twisted lugs, adding a sculptural element to its vintage form. The steel crown remains unsigned, in keeping with the period’s design ethos. Though modest in size by modern standards, the presence of this watch on the wrist is anything but small—thanks to the bold lugs and the animated ticking of the second hand.
The caseback, hands, and dial remain unpolished and authentic, lending a rich sense of patina and heritage to the watch’s overall look.
The Beating Heart – Chézard 7402
At its core lies the Chézard 7402 calibre—a rare mechanical movement with jumping seconds (seconde sautante) and date complication. This ingenious calibre was among the few made to deliver precise, deadbeat seconds without a battery, using a clever cam and lever system. Functionally mesmerizing and mechanically ambitious, it's one of the few “death beat” movements that remain accessible to collectors today.
Recently inspected and operating flawlessly, this calibre is a reminder of a brief but fascinating era in Swiss watchmaking.
