Citizen Brycen Eco-Drive Chronograph vs Citizen Corso Eco-Drive AW1231-07A

Buy the Brycen if you want a sporty chronograph you can swim in. Buy the Corso if you want a slim, quiet dress watch for the office. The Brycen packs more function: 1/5-second chronograph, tachymeter, 12/24-hour time, 100 m water resistance and a screw-back case. The Corso is smaller at 40 mm, thinner at about 9 mm and lighter at 47 g, so it slips under a cuff. Owners of the Corso praise the silver dial and black leather look but complain the strap runs small. The Brycen's 4.4 rating from 64 ratings is a broader sample than the Corso's 5 from 10.

• Choose the Citizen Brycen if you want a chronograph with a tachymeter that handles swimming and marine sports.
• Choose the Citizen Corso if you want a slim, light dress watch with a clean silver dial for everyday office wear.
