L.LEROY Vox Temporis: 43mm Officer case, calibre L601SQR with minute repeater and flying tourbillon, limited to 15 pieces. Presented at Geneva Watch Days 2026.
What It Offers
- Priced on request, the Vox Temporis places at its centre calibre L601SQR: 321 components, a minute repeater on two gongs, and a 76-part flying tourbillon, all within a 43mm Officer case limited to 15 pieces across three materials.
- Three references: LL301/1 in 18k 5N red gold with an anthracite dial, LL302/1 in platinum with a blue dial, and LL303/1 in grade 5 titanium with a silver dial.
- Time is read from a rotating dial, heard on demand through acoustic chimes, and never shown in minutes on the dial face.
- Presented at Geneva Watch Days on 26 August 2026.
Design & Mechanics
Forty-three millimetres across and 14.74mm deep including its hinged back cover, the Officer case is the defining physical fact of the Vox Temporis. The cover, a direct reference to historic pocket-watch architecture, can be personalised upon request. On the reverse, a sapphire crystal caseback framed by a polished ring with sandblasted segments and six relief-engraved fixing screws exposes the movement in full.
The dial carries no indices, no subsidiary displays, and no logo. A radial guilloché flinqué pattern finished with translucent varnish radiates from a peripheral pivot point. The arrow-shaped hour hand stays fixed; the dial rotates beneath it. For minutes and quarter-hours, the wearer activates a slide between 8:30 and 9:30 on the case band, and two finely hand-finished hammers strike their respective gongs.
Movement & Materials
Calibre L601SQR was developed and manufactured in Geneva exclusively for L.LEROY. Its 321 components operate at 3 Hz (21,600 vph), and a single barrel delivers a power reserve exceeding 90 hours. The flying tourbillon cage, built from 76 parts with a diameter of 13.60mm, completes one rotation per minute. Unlike a conventional tourbillon, it has no upper bridge, appearing suspended from below alone.
On the dial side, the tourbillon is deliberately concealed. L.LEROY chose to preserve the dial’s visual purity rather than display the complication as spectacle. The single rhodium-plated bridge carries hand-executed bevels, mirror-polished edges, and frosted surfaces finished by traditional anglage. Water resistance is rated at 3 ATM.
Market Position
The historical provenance of the Vox Temporis connects to a LEROY tact watch from 1810, created for the Prince of Hesse and today housed at the Patek Philippe Museum in Geneva. That piece allowed discreet time-reading by touch; the Vox Temporis shifts the same principle from touch to hearing. L.LEROY reintroduced the rotating-dial concept with the Bal du Temps in 2025 before carrying it forward here.
With 15 pieces produced in total across all three references, the Vox Temporis addresses a narrow collector market where acoustic complications and movement finishing carry more weight than visibility. Alligator leather straps in black, dark navy blue, or brown, each with an open-worked folding clasp bearing the interlaced double “L” in matching case material, complete a specification designed without compromise.
