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

The PCAT is the serious tool watch of the two: atomic timekeeping, five time zones, a 1-second chronograph, sapphire crystal and 200 m water resistance in a 44 mm steel case. The Corso is a slim 40 mm dress watch on leather, 9 mm thick and about 47 g, with a plain Eco-Drive movement and 30 m water resistance. Owners of the Corso like how it looks and its value, but several say the strap runs very small. Buy the PCAT if you want features and durability; buy the Corso if you want a light, clean everyday watch.

• Choose the Citizen PCAT if you want atomic timekeeping, world time, a chronograph and sapphire in a watch you can swim and shower in.
• Choose the Citizen Corso if you want a thin, light 40 mm dress watch on leather for office and casual wear.
