Corum celebrates the 21st anniversary of the iconic Bubble with the new Bubble X Ray whose design is inspired by that of one of the first models in the collection. It features a stylised skull positioned in the centre of the dial: while the large domed sapphire crystal slightly distorts the image in the light, it is clearly visible in the dark as it is totally luminescent. Likewise, the synthetic alligator strap, covered in rubber, has neon green stitching. At the heart of the watch is a self-winding mechanical movement, Calibre CO 082, beating at a rate of 4 Hz and providing 42 hours of power reserve. Visible through the sapphire glass on the case back, it is housed in a 47 mm case made of black PVD-treated steel. Both the dial and back glass are anti-reflective. Water-resistant to 100 metres, this timepiece is a limited edition of 88 pieces.
