Is the Porsamo Bleu Alexis good for swimming?

Yes. It is rated 10 ATM, which covers swimming and snorkeling. Avoid pressing the chronograph pushers underwater and skip hot showers and diving.

Does it need a battery change?

No. The movement is solar quartz, so it charges from light. Keep it in daylight or bright indoor light regularly, and expect it to run down if stored in a dark drawer for months.

What size wrists does the 37mm case suit?

37mm reads as a small-to-medium women's size and sits well on wrists roughly 5.5 to 7 inches. The steel bracelet usually needs links removed for a snug fit.

The watch on its stainless steel bracelet, typically with the brand's warranty card and a manual. Extra links are usually included so a jeweler can size it.

How does it compare with fashion watches like Michael Kors or Fossil?

It offers more on paper: 10 ATM instead of the usual 3 ATM, sapphire glass and a solar movement. Those brands offer more color and style choices and wider service networks.

Is the chronograph usable day to day?

The stopwatch subdials are handy for timing, and the date window is practical. On a 37mm dial the subdials are small, so the hands are easier to read than the counters.
