From A Blog To Watch:

I really like a lot of what Azimuth does (even though some of it is really weird), and their functional pieces are pretty great as well. The Xtreme-1 collection includes three new Azimuth watch models. This includes the SEA-HUM 3TZ (three time zones), the SEA-HUM GMT, and the Xtreme Deep Diver (with the latter being the best or worst watch depending on how you see it).

The collection is done in honor of a Mexican explorer Fernando Lozano. I am not sure who he really is or what he does, but he climbs real high, and dives real low. Maybe if I was a Latin spelunker I would know who he was a bit better. He says that he needs a watch like this, does that mean you need one as well? Probably.

SEA-HUM 3TZ and GMT are basically the same watch in style but have a durability differences. Style changes are pretty much all summed up in the bezel and the colors on the dial. The GMT has a diver’s bezel, while the 3TZ has a 24 hour scale bezel. Using the hands, GMT hand, and 24 hour bezel, you can track three timezones with the 3TZ watch. This model is also the most entry level of the bunch.

Each of the Xtreme 1 collection watches are 45mm wide, but the SEA-HUM 3TZ is thinner and has (only) 500m of water resistance. It goes up to 1,500 or 2,000 meters of resistance respectively. Here are the basic stats for the SEA-HUM GMT. Probably my favorite model. It also has an ETA 2836 movement, but a diver’s bezel, high visibility orange minute hand, and a thicker case and sapphire crystal that is 4mm wide. Note the cool 5 link metal bracelets that have torx style screws in them. Neat!
