Davosa is a Swiss brand that came about in 1987 as the demand for mechanical watches increased in the late ’80s but has roots that date back to 1861. The Argonautic series of watches get their name from Greek mythology. Argo was the name of the ship Jason set sail on to find the golden fleece. His companions were called the Argonauts.

The Davosa Argonautic is designed for the outdoor adventurist. 


Under the bonnet is a DAV 2824 automatic movement, which has a power reserve of 38 hours. Those numbers are a bit of a giveaway to the true identy of the movement, that being an ETA2824-2.

The ETA is probably one of the best known movements that come from Switzerland.

It has Incabloc shock, hand-winding and hacking. This movement runs at a frequency of 28800 bph.

With regards to the number of jewels, I couldn’t confirm but suspect there is 25.


Protecting the ETA movement is a 42mm x 14mm stainless steel case with a brand embossed screw down back. 

Looking at the front of the Argonautic Lumis there is a uni-directional bezel with a ceramic insert. Depending on the model, the insert has different coloured indices from the zero to 15 position. A luminous dot also marks the zero position.

Protecting the dial is an anti-glare sapphire crystal.


The matt black dial has small Arabic numerals around the chapter ring marking the 5 minute intervals. The hour positions are marked with luminous rectangular dashes. Double dashes at the 3, 6, 9 and 12 positions.

Luminosity does not comes from light absorption but from tritium filled gas tubes and come in colours of blue, green and orange.

The colours of the gas tubes are matched by the tip of the seconds hand, the numbers on the chapter ring marking the 15, 30, 45 and 60 minute places, highlights around the hour markers and the ARGONAUTIC name printed on the face.

Notable Features

The most obvious feature is that of the two crowns. While the one at the 3 o’clock position is for time and date setting and hand winding, the crown at the 10 o’clock position may seem a little odd. It is a manual Helium Escape Valve (HEV).

As printed on the dial, the Argonautic is water resistant to 30 ATM (300M or 1000FT).

Something that is not noticable until you look up close is the seconds hand runs under the chapter ring.

Shown in the image above is the watch with two bracelet types. The standard link bracelet model doesn’t have coloured tritium gas tubes, just luminescent. The steel mesh strapped version has the coloured gas tubes for luminescence. 


  • Tritium tubes make dial visibility easy even in the darkest or murkiest of conditions
  • Reliable workhorse Swiss ETA movement


  • Manual HEV – more for design aesthetics
