Brilliant Flying Tourbillon Yellow Sapphires





These words describe the Brilliant Flying Tourbillon collection from Jacob & Co. perfectly. Due to these attributes, this is a modern, beautiful watch for all the important moments of a woman's life, combining high watchmaking with high jewelry.

For too long, women have had to choose from restyled men's watches if they wanted something with a mechanical heart.

Jacob & Co. developed the Brilliant collection for the woman who appreciates technical watchmaking, while at the same time wants something beautiful to adorn her wrist.


The tourbillon was originally invented to be a single-axis, rotating cage secured from above as well as below to carry the regulating organ of a mechanical pocket watch for improved timekeeping performance. The version in the Brilliant Flying Tourbillon presents this more than 225-year-old invention in a yet more spectacular way.

The one-minute flying tourbillon features a delicately decorated cage that encapsulates the balance wheel, hairspring, escape wheel and a number of other crucially important components. This open-worked cage not only features an elaborate web-pattern in its architecture, but is only secured from underneath, allowing for an unobstructed and full view at the ultimate refinement of its detailing and operation. It is a constellation of superbly finished components that, when assembled and fine-tuned expertly, allows the JCAA03 movement to keep accurate time throughout its 48-hour power reserve.


Jacob & Co. is one of the few brands that has the legitimacy to create high and fine jewelry, as well as high-end watches.

The diamond and gemstones industry is a closed society, and it is really a relationship business. Sourcing the very best diamonds and gemstones depends on reputation and personal connections, and thankfully Jacob & Co. has solid, decades-long relationships.

As a result, Jacob & Co. has access to the very best sources of diamonds and gemstones from all over the world. Many of the gem-set timepieces, like the Brilliant Flying Tourbillon, require meticulous care in the choosing of stones for quality, cut, clarity, and matching color. This can take many months or years, depending on the exact colors needed.

Jacob & Co. is also an expert in the setting of these stones, working with the very best gem setters in the industry.


The 47mm 18K rose gold case of the Brilliant Flying Tourbillon is completely invisibly set with baguette-cut precious stones. Covering the front and back of the timepiece are anti-reflective sapphire crystals.


The dial of the Brilliant Flying Tourbillon is completely invisibly set with baguette-cut precious stones. Extremely challenging to perfect, the invisible setting shows no supporting metal between the stones, making the stones seem bigger.
