Is the AR60011 a real automatic watch?

Yes. It is listed as an automatic chronograph, so it winds itself from the motion of your wrist and has no battery. Expect to reset it if it sits unworn for a couple of days.

How does it compare with a Tissot or Hamilton automatic chronograph?

Those brands are watchmakers with documented movements and stronger service networks. The Armani leans on design and brand name; the Swiss alternatives lean on horological credibility and resale.

What does the chronograph do?

The pushers run a stopwatch for timing events, with the elapsed time shown on the subdials. The rest of the dial tells the time as normal.

Does an automatic chronograph need servicing?

Yes. Mechanical movements need periodic servicing, typically every few years, and chronograph work adds to that cost. Factor it into ownership.

Is it a good everyday watch?

It works as a daily wear if you like a busy blue chronograph dial. It is less understated than a plain three-hand watch and less robust than a dedicated sports watch.
