Which is better for daily wear?

The PRX. Its slimmer 40mm case, sapphire crystal and 80-hour reserve make it easier to live with day to day. The Seiko is the better pick if you want a bezel and day/date.

Both are durable steel automatics. The PRX's sapphire crystal resists scratches far better than the Seiko's Hardlex, and its longer reserve is gentler on the movement if you skip days.

Is the PRX worth stepping up to?

If sapphire, a Swiss movement and a longer reserve matter to you, yes. If you want a bezel, day/date and easy strap changes, the Seiko gives you more functions.

The PRX. At 40mm and slimmer, it sits closer to the wrist. The Seiko's 42.5mm width and 13.4mm thickness feel noticeably bigger.

Can I swap straps on both?

The Seiko uses standard 22mm lugs, so most straps fit. The PRX has an integrated bracelet, so you are largely limited to Tissot's own quick-release options.

Which has better lume?

Both are good. The Seiko's LumiBrite is bright and long-lasting; the PRX uses Super-LumiNova on its indexes and hands. It is close to a tie.

Seiko 5 Sports SRPD59 vs Tissot PRX Powermatic 80

The Tissot PRX Powermatic 80 is the better watch for most people: a Swiss automatic with an 80-hour power reserve, sapphire crystal and a slimmer 40mm case. The Seiko SRPD59 is the tougher, more playful pick, with a day/date, LumiBrite and a rotating dive-style bezel. Owners praise the Seiko's value and legibility but note the Hardlex crystal scratches and the 42.5mm case wears large. PRX owners like the slim profile and long reserve but find the integrated bracelet limits strap swaps.

Choose the Seiko 5 Sports SRPD59 if you want a rugged everyday sports watch with a day/date, strong lume and a rotating bezel.
Choose the Tissot PRX Powermatic 80 if you want a slim Swiss automatic with sapphire crystal and a long power reserve for daily and dress wear.
