Linde Werdelin - Oktopus Blue Sea

It has a 44 x 46 mm case made of ALW (Alloy Linde Werdelin), a material designed for the aerospace and Formula 1 sectors and reproposed by Linde Werdelin, the new Oktopus Blue Sea, a diver's watch that is water-resistant to a pressure of 30 atmospheres. Linde Werdelin also subjects the ALW alloy to a protective surface treatment, which makes it even more resistant, while maintaining its exceptional lightness (its specific weight is half that of titanium). The screw-locked crown is made of titanium, as is the case back (in this case grade 2 titanium), which is engraved with a stylised octopus. The bezel is ceramic and is secured by means of titanium screws with an Allen head. What catches the eye, however, is above all the multi-level dial, with its skeletonised upper part and the date at 12 o'clock (note the two date discs themselves skeletonised and visible from the dial side). The dial itself, takes on various shades of blue depending on the intensity of the light: in practice, the less light the watch is exposed to, the more intense the hue will be. This is made possible by the use of 'Badgerite lume', a compound developed together with Super-LumiNova Swiss. Three colours are used, namely 'Aqua Blue', 'Ultramarine' and violet, which, as mentioned, become more and more intense as the intensity of the external light decreases. The movement used is a Dubois-Dépraz manufacture (26 jewels, 28,800 vibrations per hour, power reserve between 40 and 44 hours), calibre 14580, mechanical with automatic winding.
