Davosa makes some very nice watches. I have reviewed their Professional TT, and their 46mm Titanium. Both were fantastic. Now I have got my hands on their Davosa Argonautic Lumis and I am really liking this one. It’s a bit of a mix of Rolex and Omega, and it has tritium tubes. Lets check this out.

The Dial

Although the case on this watch looks like an homage fusion, the dial is its own. The hour markers are tritium tubes, and surrounding them is a minutes/seconds index ring. The dial is very clean looking and looks great with the little bits of red contrasting the black face. The hour and minute hands. those look like little rockets to me (read: pretty cool). The hands are mounted to the Swiss Made Davosa DAV3021 movement, which is basically an ETA 2824-2. Can’t go wrong with that. All of this is protected by an AR coated sapphire crystal.

The Case

The case on this Davosa Argonautic Lumis looks like a fusion of a Rolex Submariner and Omega Seamaster. That’s a wonderful thing since those are two of my favorites. The ceramic bezel is very much Rolex and the helium valve at the 10 o’clock position is much like the Omega. Now most folks do not need a helium valve but for the few commercial saturation divers out there, this watch is a good option.

For all regular divers out there, the 1000ft of water resistance is plenty good for what you need. The case size is right where I like it at 42mm. Made from stainless steel with a brushed finish this case just looks great. Build quality is very good with no issues found at all. The bezel is solid with a tight feel when rotating.

The Bracelet

I have worn this watch for a week now and this bracelet has been just fine. Most issues I have with lower-quality bracelets is pinching and hair pulling. This for sure is not low-quality, and there are no pinching or hair pulling issues at all. Made with the same brushed stainless steel this really looks great and fits very snug to the case. The clasp is double locking and has a divers extension. There is no way this is accidentally coming off.

The Lume

There is no painted lume on this Davosa Argonautic Lumis. The glow comes from tiny glass vials filled with tritium gas, which is an isotope of hydrogen. These vials are coated with a phosphorescent paint which react with the tritium gas. The most common tritium watches use T25 tritium tubes which have 25 millicures of tritium gas. What’s so cool is that these will glow non-stop for up to 25 years.

Overall Impression

This watch has it all for me. It’s a real dive watch that looks like my two favorites watch brands and it has tritium tubes. It’s cool looking, unique, and built for work and play. For $849 USD you get a lot for the money. If you like what you see go check them out at davosa-usa.com.
