Citizen Brycen Eco-Drive Chronograph vs Citizen Eco-Drive Promaster Diver BN0191-55L

Buy the Promaster Diver if you want one watch for swimming, diving and daily wear. Its 200 m rating, ISO-compliant dive build, one-way rotating bezel and steel bracelet make it the tougher, more versatile pick, and owners rate it higher. The Brycen is the better looker for casual and dress wear: a chronograph, tachymeter and brown leather strap on a lighter case. Both run on Eco-Drive solar and never need a battery. The Brycen's mineral crystal and leather band are the weaker points for hard use.

• Choose the Brycen if you want a chronograph with a tachymeter and a leather-strap sport look for casual wear, and you rarely go near deep water.
• Choose the Promaster Diver if you want a rugged dive watch you can swim and snorkel in, with a steel bracelet and a rotating timing bezel.
