2024.02.11

Jean-Claude Biver, who has a career spanning more than half a century in the watch industry, has finally unveiled the masterpiece that bears his name. The finishing touches are as impressive as the packaging.

Carillon Tourbillon Biver

Carillon Tourbillon Biver

Ti case (diameter 42mm, thickness 13.7mm). Water resistant to 5 bar. Starting at 520,000 Swiss francs.

"Carillon Tourbillon Biver" with carillon, tourbillon and micro-rotor

Jean-Claude Biver

Jean-Claude Biver
Founder of Biver. After working at Audemars Piguet, he joined the ASUAG Group (now the Swatch Group). After reviving Blancpain in 1982, he became CEO of Hublot in 2004. Based on the concept of fusion, he quadrupled sales in two years, and then became president of the LVMH Group watch division. In 1922, he founded JC Biver (now Biver), which bears his name.

 Biver had been quiet since its announcement in March 2023. However, in December, Jean-Claude Biver himself came to Japan and unveiled the product at the Hour Glass Ginza.

 We asked him directly what we wanted to know. Why did he choose the cutting-edge Le Cercle des Horlogers as his partner? "Because there was no other manufacturer that could add a carillon, tourbillon, and micro-rotor to a repeater. They were able to meet our custom needs." But did he have any concerns about working with an up-and-coming manufacturer?

"The company is new, but the staff has a lot of experience. I don't work with companies. My company is only 16 months old, but I have 50 years of experience."

 One of the models he showed me was the "Carillon Tourbillon Biver," featuring a carillon repeater, tourbillon, and micro-rotor. The finish is impeccable. The plate and bridges are made of 18K gold. The bridges feature 196 rhombus-shaped ridges (though it seems unnecessary to mention this on the micro-rotor). The dial is made of 1.15mm-thick sodalite.

The movement, Cal. JCB-001, is 34mm in diameter. Its base is made by Le Cercle des Horlogers, but incorporating Biver's personal preferences resulted in a completely different piece. Despite the micro-rotor, the thickness was deliberately increased, allowing for clever stacking of the carriages and a three-hammer carillon to be mounted. The baseplate and bridges are crafted from 18K gold.

 However, what impressed me even more was the overall packaging. The exterior is made entirely of lightweight titanium. The lugs are also short and the bow tube is tight, so it fits comfortably on even the slenderest of wrists. When I told him this, Biver looked pleased. What's more, even though it's a repeater with a slider, it's water resistant to 5 bar. Despite being an ultra-complicated watch, it's not overly flashy, as it's aimed at collectors, Biver said.

 To be honest, the price is exorbitant, but the complicated watch that master watchmaker Biver finally completed was of such a high level of perfection that it was well worth the price.
