Eterna has unveiled, ahead of its official debut at Baselworld 2016, the first image of the upcoming Eterna Super KonTiki Diver Chronograph (below), which takes its inspiration from the redesigned base model that was introduced in 2015.

The Eterna KonTiki collection, famously named after the wooden raft used in Norwegian explorer Thor Heyerdahl’s 1947 ocean expedition, features a new flyback chronograph movement, Caliber 3916A, designed and manufactured in-house by Eterna. It is part of the “39” family of Eterna movements, with a balance wheel oscillating at 28,800 vph, at least 60 hours power reserve, rhodium finishing on the surfaces of the components, and microblasted decoration on the rotor.

The case of the Eterna Super KonTiki Chronograph is in polished and brushed stainless steel, measures 45 mm in diameter, and has a screw-locked crown and rotating bezel. It has a scratch-resistant sapphire crystal and is water-resistant to 200 meters. The watch will be available on a rubber strap (as pictured; $4,700) or a Milanese steel bracelet ($4,900).
