Eterna KonTiki 200m Swiss Automatic Dive Watch 633.1570.41 Overhauled

The Eterna-Matic KonTiki 200M (Reference 633.1570.41) is a highly regarded 1990s diver reissue. It is famous among collectors because Eterna built it using actual remaining, unutilized vintage “Super” cases from 1963, combining pure 1960s case architecture with upgraded 1990s mechanical components.

This watch is on a vintage Acier Tropic strap and was just overhauled. All original parts. The crystal has a crack but was left because it is original. I will include a correct-size crystal if you want to get it replaced.

Key Specifications:

• Case Dimensions: 39.5mm diameter by 14mm thickness, featuring a 20mm lug width.

• Movement: ETA 2824-2 automatic caliber.

• Crystal: Slightly domed acrylic crystal with a distinctive, under-mounted date cyclops magnifier at 3 o’clock, leaving the external profile smooth to the touch.

• Bezel: 120-click unidirectional black dive bezel.

Because of its limited production and unusual history, this reference is seldom seen on the market. The dial and hands use a lume that ages into a beautiful light parchment or tritium-like patina over time, even though the dials are not explicitly marked as tritium.

The minute hand lume is damaged but is all original.
