Breguet Minute Repeater No.7637

In 2008, Breguet came out with a new way of minute repeaters, fitting them with an entirely re-engineered movement incorporating new materials and featuring innovative positions for the gongs, gong rests and hammers. This patented technique is now in service on Breguet minute repeater no. 7637.

Breguet Minute Repeater 7637 watch in white gold

Its large, 42 mm white or pink gold case houses a manual-winding mechanical minute repeater movement (Breguet caliber 567/2) featuring running seconds at 9 o’clock and a 24-hour (day/night) subdial at 3 o’clock. The crystal-clear sound issuing from the case had never been heard before in any repeater without chimes.

The gold gongs match the color of the case while the hard-metal hammers have been polished and beveled. The hand-wound movement visible through the clear sapphire case back has been entirely chased by hand while, in true Breguet style, the dial is manually engine-turned silvered gold.

Breguet has also created a high jewellery version of the minute repeater watch. The Classique Grande Complication 7839 ~ Haute Joaillerie Minute repeater adds the prestige of baguette diamonds to the minute repeater function. Ideal for conveying sound vibrations beyond the case, diamond’s hardness and pureness further improve the watch’s sonority by reducing vibration loss to a minimum.

Following the lead of major sound-system specialists whose loudspeakers now feature diamond conduction, Breguet has decided to introduce a fully diamond-set design whose setting is as perfect as the acoustic performance of its minute repeater. Watch 7639 emits a spectacularly pure sound that is certain to delight any connoisseur of ringing or chiming Grande Horlogerie. Including its bracelet attachments, crown and dial, the case is entirely covered in invisibly set diamonds.
