My research on the net didn’t turn up much, except that the brand seems to still exist. There are sources that claim that Sicura made these models for Arios. It reminds me a little of Sicura in terms of case and back. But: I can say a little about the origin of Arios. It runs perfectly and the patina is as a watch of this age can tolerate. Sometimes you win when you buy an old watch and sometimes you lose. You can still find such a model today, for example on ebay or in forums, although they are quite rare. I can’t remember when I bought the watch.

It was something special, a kind of tool like a ruler or metre rule and at the same time an aid for calculations.īut honestly: I think it just looks great! That’s why I don’t care about the brand. The slide rule accompanied my father as an engineer in his daily life and we also used these tools at school. But, as a child of the 70s, I remember too well how such functions were something special back then. I like the many functions, even though I don’t use them in my job or hobby. Functions, patina and a design that beautifully presents form and function.įor me, however, it’s more the soft facts that count. Here are the exact data of the movement: Ĭase dimensions: 44 mm diameter and 46.5 mm from top to bottom. Movement: Manual winding, RL 1217-21 from Ronda. It also has a date and weekday indicator. Tachymeter: The white bezel ring is used to calculate the speed. Unfortunately, I don’t have a manual for it and my days of using a slide rule are over. Slide rule: with the outer rotating bezel you can calculate. World time: with the upper of the two crowns, you can set the world time to different cities via the inner ring. The “hard” facts about the beautiful Arios watch are the following stunning specifications:

World time and more: the Swiss watch pocket knife.
