Which is better for swimming?

The Promaster. Its 200 m rating is dive-grade, while the Brycen's 100 m is fine for swimming but not diving. The Promaster's rubber strap also handles water better than the Brycen's leather.

Is the Brycen worth saving $31?

Yes if you want a chronograph and leather band for everyday and office wear. The saving buys a dressier look, but you give up 100 m of water resistance and dual time.

Do either need a battery?

No. Both use Citizen Eco-Drive solar movements that recharge from any light source, so neither needs a battery replacement.

Which fits a smaller wrist?

The Promaster, at 42 mm. The Brycen is 44 mm wide and 12.1 mm thick, which wears large on wrists under about 7 inches.

Which has more functions?

The Brycen adds a chronograph. The Promaster adds dual time for a second time zone. Both have a date window.

Both are stainless steel with mineral crystal and solar movements, so lifespan is similar. The Promaster's rubber strap and higher water rating hold up better to wet, active use; the Brycen's leather band will wear sooner with water exposure.
