Citizen Brycen Eco-Drive Chronograph vs Citizen Eco-Drive Military Field Watch

Buy the Brycen if you want a bigger, sportier chronograph with a tachymeter and a leather strap. Buy the Military BM8180 if you want a small, light field watch that disappears on the wrist and reads at a glance. The Brycen is the more feature-loaded watch; the Military is the simpler, tougher everyday one. Owners of both praise Eco-Drive for never needing a battery, and the Military's long track record and clean dial win over shoppers who want a no-fuss watch.

  • Choose the Brycen if you want a 44 mm chronograph with a tachymeter, 12/24-hour time and a leather strap for sport and casual wear.
  • Choose the Military if you want a compact 42 mm field watch with a nylon strap, day-date and a clean, legible dial.

What reviewers say

Citizen Brycen Eco-Drive Chronograph

  • 4.4 / 564 ratings

Rated 4.4 out of 5 from 64 ratings, the Brycen is generally well received as a solid solar chronograph. Owners like the blue dial and the no-battery Eco-Drive setup. Some note the size and the leather band as drawbacks.

Citizen Eco-Drive Military Field Watch

Owners of this Citizen field watch praise the set-and-forget solar movement and the light, comfortable wear. Many call it a solid everyday beater for the money. Complaints center on the mineral crystal and the plain strap.

What people mention
  • Solar movementPraisedOwners like that it charges from any light and keeps running without battery swaps.
  • Comfort and weightPraisedWearers say the watch is light and easy to forget on the wrist.

  • CrystalCriticisedSome owners report scratches on the mineral glass with regular use.

Questions and answers

Which is better for swimming?
Both are rated to 100 m, so either handles swimming. The Military's nylon strap dries faster; the Brycen's leather strap will degrade with repeated soaking.
Which is easier to read?
The Military. Its clean dial, Arabic numerals and luminous hands read at a glance. The Brycen's chronograph subdials and tachymeter make it busier.
Do either need a battery?
No. Both use Citizen Eco-Drive, charged by any light source. The Military's E101 movement is rated for about six months of power reserve in the dark.
Which suits a small wrist?
The Military. Its case is smaller and it weighs less, so it sits closer and feels lighter. The Brycen's 44 mm case is noticeably larger.
Is the Brycen worth stepping up to?
Only if you want a chronograph and tachymeter. If you just need time, day and date, the Military does that with less bulk and a tougher strap.
Which lasts longer?
Both are durable steel watches with mineral crystals. The Military's nylon strap outlasts leather in wet use, while the Brycen's leather shows wear sooner if you swim or sweat in it.
