The first C60 Sapphire broke the mould – and sales records, too.
Then the conversations began: could we do another C60 Sapphire? How would we make a watch that wasn’t just the equal of the original but something with its own unique character?
The answer to that is the C60 Sapphire Black.
Like the original C60 Sapphire, the dial is made from ultra-thin, scratch-resistant sapphire. However, here, the sapphire has been ‘smoked’ – something that’s achieved through a complex process called physical vapour deposition (PVD).
This involves placing the sapphire in a vacuum chamber filled with a vapour of silver and carbon graphite – heated to 400°C – for three hours. It’s then put in another chamber, this time filled with silicon oxide vapour, which adds protection.
The result is a subtly tinted transparent dial that allows you to see deep into the Sellita SW200-1 movement. And with a compressive strength of 2,000 megapascals, it’s not just beautiful but incredibly tough, too.
The dial is only part of the story. Turn the watch over and you can see the movement from behind thanks to the sapphire caseback, while the Light-catcher™ case is not only graceful but thin enough to slip under a shirt cuff. And at 40mm in diameter, pretty much suits every wrist.
Engineered to the requirements of a professional diving instrument, the watch is water-resistant to 600m, while the unidirectional bezel allows you to time your ascents – a vital safety tool for subaqua divers.
Finally, power comes from the highly regarded Sellita SW200-1 movement, which delivers accuracy under the most testing of conditions.

Sellita SW200-1 Automatic
An update on the classic Sellita SW200, this Swiss-made self-winding movement is known for its accuracy and reliability.
The 26-jewel movement boasts a date wheel, a 4Hz frequency (equating to a smooth eight ticks per second) and a 38-hour power reserve. It also has an in-built anti-shock system to maintain accuracy when faced with any sudden jolts.

See the magic
The pure sapphire dial has been shaved to just 0.8mm, which allows you to see the Sellita SW200-1 movement inside. The smoked colour is achieved by exposure to silver and carbon graphite vapour in a vacuum-sealed chamber. The sapphire goes through 20 steps and 80 operations before it’s ready.

A case for all wrists
The Light-catcher™ case boasts a mix of brushed and polished surfaces and graceful lines that make it look and feel slim. It also sits snugly on the wrist – and at 40mm it suits every width of wrist.

Back story
The Sellita SW200-1 is a beautifully engineered movement. Something you’ll be able to appreciate when you look through the see-through sapphire caseback and see it whirring away.

Glow pressure
The hands and indexes have been coated in Super-LumiNova® Grade X1 GL C1, delivering outstanding luminosity in low light. Check out the contrast between the hands and indexes, and the sapphire dial.

Boss the bezel
The watch’s unidirectional bezel is a vital timing tool for diving ascents. Made from marine-grade stainless steel, it’s been precision-engineered to deliver a satisfying – and reassuring – ‘click’ whenever it’s used.
