Seiko 5 Sports SRPK31 vs Tissot PRX Powermatic 80

The Tissot PRX Powermatic 80 is the stronger all-rounder: an 80-hour power reserve, sapphire crystal and a slimmer 10.9mm case beat the Seiko 5 Sports on specs that matter daily. The Seiko wins on character and fit: a 38mm case, 44.2mm lug-to-lug and a rotating dive bezel suit smaller wrists and give it a sportier, more tool-like feel. Owners of both report solid finishing for the class; the Tissot's integrated bracelet and blue dial read dressier, while the Seiko's beige dial and day/date read casual. Buy the Tissot for a one-watch daily; buy the Seiko if you want a compact diver-style automatic with a bezel.

• Choose the Seiko 5 Sports if you have a smaller wrist, want a rotating elapsed-time bezel and a day/date, and prefer a casual dive-watch look.
• Choose the Tissot PRX Powermatic 80 if you want sapphire crystal, a long 80-hour power reserve and a slim integrated-bracelet watch that works with a shirt.
