The quick answer.
Tissot PRX Powermatic 80 Green is a 40 mm everyday watch at $723.20. We recommend it for a buyer who wants a Swiss automatic with a distinctive colour that still works with a suit or a T-shirt.
Why it belongs on the shortlist.
Tissot lists a light green dial with index markers, and the waffle texture catches light across the dial. It is the PRX we would choose if you already know the blue and black and want something more individual.
Our verdict: the PRX for people who want a colour.
The PRX comes in a lot of dials. Green is the one that people notice for the right reasons. It is lighter and less saturated than a racing green, so it reads as fresh on the wrist, and the steel bracelet keeps it smart. The mechanics are identical to the rest of the 40 mm range.
What you get for the money.
Tissot lists a Swiss automatic with an 80-hour reserve and a Nivachron balance spring, a sapphire crystal with an antireflective coating underneath, a see-through caseback and 100 m water resistance. For how reserve affects daily use, see our power reserve guide.
Size and fit.
Tissot lists a 40 mm case width, 39.5 mm case length, 10.93 mm thickness and a 12 mm integrated lug width. The compact case suits most wrists, and the 35 mm PRX is there if you want smaller.

Before you choose
The saving against Tissot is substantial, but this is still a $700 watch, and the integrated bracelet decides the fit. Tissot lists a 40 mm case width with a 39.5 mm case length.
Who it suits.
A buyer who wants a Swiss automatic with a distinctive colour that still works with a suit or a T-shirt.
When to choose something else.
Choose the black PRX if you want the most neutral version, or the quartz PRX if you do not need an automatic.
Warranty, returns and ownership.
Watches of America lists a one-year retailer warranty and a 30-day return window on eligible items; conditions and a restocking fee may apply. Tissot’s own warranty is described for purchases through its boutiques and authorized retailers, and the listing does not say whether it carries over here, so ask Watches of America to confirm in writing if manufacturer coverage matters to you. Shipping is listed as one to three business days with free shipping available.
