So, the Swatch group has decided to whore out all of their companies with these watches aimed at the Gen Z generation. At least the ones that can read an analog dial.
From the horse's mouth: "Blancpain and Swatch are teaming up for a non-limited collection of five models full of joie de vivre, colour and technology. Together, the two Swatch Group brands are diving into the five oceans of the blue planet, combining the best of both brands with innovative, bioceramic, water-resistant timepieces and a mechanical movement with a 90-hour power reserve.
These five Blancpain X Swatch models are made from bioceramic, a unique and patented blend of two-thirds ceramic and one-third biomaterials derived from castor oil. While the colours chosen for this collaboration clearly indicate that this is not a traditional Blancpain watch, all fans and enthusiasts will recognise at first glance many of the features and characteristics of the iconic Fifty Fathoms, as well as nods to the Swatch Scuba collection."

"The watches in the Bioceramic Scuba Fifty Fathoms Collection are equipped with Swatch’s mechanical movement SISTEM51. Launched in 2013, Swatch SISTEM51 is the first and only mechanical movement whose production is entirely automated. This Swiss-made mechanism features just 51 parts including only one central screw, has a 90-hour autonomy and is fully anti-magnetic thanks to its hairspring made with Nivachron™, ensuring high precision. "
Wow, a Blancpain for $400.
Did you know the straps are made from recycled fishing nets?
