Inspired from the complex nature and symmetrical composition of Octopus, Jacob & Co. has created a unique edition of its Astronomia model: the Astronomia Octopus, which houses a hand-crafted sculpture of an octopus through the Astronomia’s signature gravitational triple-axis tourbillon.
Taking into consideration both the sophistication of the design and the comfort of the wearer, the intricately handcrafted sculpture of the Octopus is composed of titanium. While titanium is ideal for adorning the movement without adding significant weight to the piece (the octopus weighs just 2.83 grams) the material is notoriously difficult to engrave or sculpt, making it all the more difficult to bring the piece to life.
The first Astronomia model to include a sculpture in the core of its composition, the Astronomia Octopus is displayed as a true work of art, cased in a new sapphire monoblock casing that allows the sculpture and complications to be admired from multiple angles. The entirely transparent monoblock case was originally created for the brand’s limited addition Astronomia Flawless. In both models, it creates the illusion that the complications inside the timepiece are suspended in mid-air, as the only non-sapphire elements are the two bows on the back to wind the movement and set the time.
The sapphire components of the Astronomia Octopus take a staggering 37 weeks to produce and each component requires at least a dozen different operations in its production. This excludes the time it takes to engrave the piece and the octopus sculpture, as well as the time allocated to assemble and meticulously hand-finish the movements.
Since its initial launch just under three years ago, Jacob & Co.’s Astronomia Tourbillon has consistently evolved with the introduction of each new model. Because of the additional layer of complexity added by the octopus, the Astronomia Octopus is piece-unique.
