Jacob & Co

New York-based jewellery and wristwatch retailer Jacob & Co has pulled out all the stops with its Astronomia Solar, the latest addition to the Astronomia collection. A mini cosmos in its own right, the movement rotates completely clockwise every 10 minutes and carries seven planets crafted from precious stones, including a jasper Mars, rhodonite Venus and tiger eye Saturn, complete with a rose gold ring, all sealed in anti-reflective sapphire glass.
