This watch comes in a 42mm stainless steel case with a manual wind movement holding a 40 hour power reserve, a GMT indicator at 9 o’clock, a day/night indicator at 3 o’clock and of course, the undeniable star of the show, and the raison d’être of the watch: a tourbillon.


Different dial and strap versions are available for this particular model but they all veer towards classical designs, with a few modern elements peppered about and a good sized onion crown for hand winding duties. All in all, it’s a moderately attractive design and in many ways I like it.

This version with the black dial is a mix of silver roman numerals and blue painted-on text. There is a raised 3D sunburst pattern in the background which is a nice touch, and flows in well by giving more body to the dial and a somewhat refined look.

The inclusion of the GMT indicator at the 9’o clock position makes this a useful watch to have even if it is a little difficult to read by virtue of its small size. Still, it makes the overall package more attractive, and certainly something for a frequent traveler to consider who only occasionally needs to check home time, and who in moments of boredom while waiting for flights, can turn to the dance of the tourbillon on the wrist.

Setting GMT is easy to do even though I had to look through the watch forums to find instructions. Pull out the crown and move the main hands clock wise and you will find that the GMT hand moves forward too. Pay attention to the time you want for GMT and set that first. Then, turn the crown in the opposite direction (main hands counter clockwise) to set the time. At this point, you will notice that the GMT indicator remains fixed at the point you last left it, allowing you to program your GMT offset.

Do note as well that the day/night indicator is only synced to the main hands.

The name AATOS means “thought” in Finnish, and is to me a rather intelligent sounding and inspired choice for a brand name, being short and meaningful, as well as easy on the eye in its chosen font on the dial. While I am happy with the overall package, I do have to say that the included signed strap is not of good quality. Though this is par for the course and very much to be expected.
