Two years ago, Bell & Ross introduced the BR 03-92 Diver, which more recently made its debut in a bronze case. Now to mark 15 years with Singapore watch retailer Cortina, B&R has unveiled the Demiurgus, a limited edition diver that combines the bronze case with a khaki green dial, which will be available only online.

Greek for “creator”, the Demiurgus diver has a 42mm case made in satin-polished CuSn8 or phosphor bronze, an alloy that contains 92% copper and 8% tin. In contrast to aluminum-based bronze alloys, like that used by Tudor for instance, CuSn8 is reddish in colour and develops verdigris, or a greenish patina.

The military green dial sticks to a tried and true dive watch template, with applied dot indices and elongated quarter markers, which are gold-plated and filled with Super-Luminova.

Dial aside, the Cortina edition has the same specs as the stock model. That means a case that measures 42mm by 42mm.

But unlike the standard BR 03 models, the diver is rated to 300m and adheres to the ISO 6425 standard for dive watches. The water-resistance is achieved in part by fortifying the crystal and back, making it thicker than the standard model. The sapphire crystal is 2.85mm thick, compared to 1.8mm on the ordinary BR 03-92, while the case back is 2.8mm.

It features a unidirectional bezel that extends slightly over the edge of the square case middle, leaving ample teeth for grip. Another element unique to the diver case are the crown guards and a rubber-coated bayonet lock crown.

The movement inside is the BR-CAL.302, which is a Sellita SW300. It sits inside a soft iron cage that offers protection from magnetic fields of up to 80,000 A/m, which is the same level of magnetism resistance as a Rolex Milgauss (unsurprising since the Faraday cage is the same).
