The Oktopus has been crafted with the diver in mind. Along with the dive instrument – The Reef –, this new model is the ultimate diving accompaniment for any diver. The Oktopus is the first Linde Werdelin watch to have different case dimensions, clever l y incorporated in its design in order to increase the water resistance to 1111 m while also still being able to take both instruments attached on top of it. The thickness of the case has been increased by an additional 1.5 mm, while the sapphire crystal has also been made thicker by 1.6 mm increasing it to a 3.8 mm in order to withstand pressure of more than 110 ATM. The new model also carries an integrated Helium Escape Valve that ensures the watch endures the pressure during resurface time. For the first time, a Linde Werdelin dial carries Arabic numerals and the hands are thicker while both are applied with Super LumiNova making the watch very easy to read at depth.
