Tourbillon Chiming Jump Hour – Akrivia

The Akrivia Tourbillon Chiming Jump Hour is a remarkable timepiece that seamlessly integrates three sophisticated horological complications: a tourbillon, a jumping hour display, and an hour-striking mechanism. This combination is unprecedented in fine watchmaking, showcasing Akrivia's commitment to innovation and craftsmanship.

Key Features:

• Movement: The manually wound AK-03 movement is entirely developed and produced in-house by Akrivia. It comprises 275 components and 26 jewels, operating at a frequency of 21,600 vibrations per hour (3 Hz). The movement offers a substantial power reserve of approximately 100 hours.
• Tourbillon: Positioned at 6 o'clock, the tourbillon has a diameter of 13.7 mm and weighs 0.36 grams. It completes a full rotation every 60 seconds, enhancing timekeeping precision by counteracting the effects of gravity.
• Jumping Hour Display: The hours are displayed digitally through an aperture at 12 o'clock, advancing instantaneously at the top of each hour. This is complemented by a central minutes hand, providing a clear and legible time display.
• Chiming Mechanism: At the exact moment the hour jumps, a steel hammer strikes a curved gong, producing a chime to audibly signal the passing hour. A pusher located at 3 o'clock allows the wearer to activate or deactivate the chiming function, offering flexibility in various settings.
• Case and Dial: The watch features a 43 mm case with a thickness of 12.9 mm, crafted from stainless steel. Both the front and back are fitted with sapphire crystals treated with anti-reflective coating. The black steel dial boasts a matte-polished finish, enhancing the visual appeal of the timepiece.
• Finishing: Exemplifying haute horlogerie standards, the movement is adorned with 66 inward angles, black polish, Côtes de Genève, hand graining, hand polishing, rhodium finishing, manual circular graining, and hand engraving. These meticulous finishing techniques highlight the exceptional craftsmanship involved in its creation.

Additional Information:

The Tourbillon Chiming Jump Hour is presented on a hand-sewn black alligator strap, secured with a pin buckle engraved with the Akrivia logo. The watch is water-resistant up to 3 ATM (30 meters), ensuring durability alongside its intricate mechanics.
