Citizen AT4129-57H Review: Eco-Drive Grey Dial Men’s Watch

If you’re on the hunt for a sharp-looking watch with exceptional timekeeping capabilities, then the Citizen AT4129-57H could be the ideal watch for you.

This model has a very professional design.

The grey, white, and red colors used on the dial make it pop, allowing for you to read the time really easily.

This piece is also packed with functions.

With Atomic Timekeeping options, a chronograph, a perpetual calendar, and a tachymeter.

All of these complications add a great deal of function to a watch that works great with both formal or casual outfits.

And in this Citizen AT4129-57H review, I’ll tell you what makes this piece a good watch.

  • 43 mm two-tone stainless steel
  • Grey sunray dial with chronograph, day-date, 24-hour display, alarm, perpetual calendar, tachymeter, and power reserve indicator
  • Brushed and polished stainless steel band


  • Atomic Timekeeping makes sure the watch is always precisely on time
  • The sleek and sharp design looks good with both formal and casual outfits
  • The perpetual calendar automatically adjusts for days of the month
  • 200m of water resistance means this watch can be worn in the shower and even for swimming


  • Setting up the watch is pretty complicated

A Killer Design

The first thing that strikes me about this design is how they managed to fit all the watch’s functions on the dial without making it look cluttered.

The chronograph, atomic timekeeping, and calendar are all laid out on sub-dials that do a great job of complimenting the main dial.

This is possible also because of the watch’s large 43mm case.

With the rise of larger men’s watches, this model fits right in.

When the large case is paired with the stainless steel strap of this watch, it results in a very classy, modern, and sleek design.

It would be no problem at all for you to wear this watch casually during the day and with your best suit in the evening.

That’s how flexible this piece’s design is.

Premium Timekeeping

Atomic timekeeping means your watch will never lose time.

Without getting into the gritty details, atomic timekeeping simply means that the watch receives radio signals to sync the watch with NASA’s atomic clock, which is the most accurate time in the world.

Powering this feature can use a lot of power, which is why Citizen chose to use their ever-popular Eco-Drive movement.

This movement at its heart is a Japanese Quartz movement.

Meaning it will be very accurate even with the atomic timekeeping feature off.

But the coolest part of the Eco-Drive is it gets its power from a solar panel on the dial instead of a battery.

Meaning that this watch will keep ticking as long as it gets regular exposure to light.

Customer Scores And Reviews

Doing my own research on the watch wasn’t really enough for me to form a solid opinion.

That’s why I went to the Amazon review section to see what other customers thought of the piece.

A lot of them loved it.

They really loved how the design was very complex with a lot of tiny details, but it doesn’t seem cluttered hard to read.

However, there were a couple of reviewers who did not enjoy the watch’s setup process.

It does take a while to set the watch up, especially the atomic timekeeping feature.

This isn’t much to worry about though, because once you get passed the set-up process you won’t have to worry about doing that again.


Those with a sleek and classy style and a love for precision will enjoy this piece the most.

The watch’s size, colors, and overall design will allow you to wear it every day, no matter what event you’re going to.

So if you like looking sleek while also being on time, then this timepiece belongs on your watchlist.
