Even though every review is subjective, I would dare to recommend it as it is a "value for money" watch, especially if you find it under 400 Euros, ideal for divers, professional divers (mixed gases) as well as for any enthusiast of diving watches. Legendary reliability, I have had it for many years (with "clumsy" handling), it also has a good fit for individuals with a large wrist circumference.

incredible watch ...I have the limited edition ....the only bad thing is that it's not for wearing all the time, it gets tiring because of the weight.
.but still it's worth every euro.....

The watch is incredible. It is perfect. It is both a jewel and a tool. Only those who have it understand what it is. In my opinion, it is not expensive. I got it for 262 euros. I have similar watches, but they cost around 800 euros (Luminox and Casio). It is very easy to read the time, even at night. Because it is large in size, I have the strap slightly loose. One of the best choices for a watch.

It is an old model, I have had it for about 13 years and it has been used in several dives as well as everyday use. It has never caused me any damage, it is worth its money and more for people who do diving and more!

The watch is purely for diving, it is not meant to be worn with a suit but for its intended purpose it is perfect. Certified with ISO 6425 300m diver at this price there is no other, no matter how much you search. The ultimate watch for diving and water sports.

This watch is only for divers. When you wear it, it feels like a brick. I sold it because it was too uncomfortable on my wrist. It's a terrible watch, not even worth giving as a gift

It is the third Citizen watch that I have bought and I really don't know what to say about this brand..
The watch doesn't lose a second, just like all Citizen watches..
You can easily see the time at night.
It is sturdy in the hand, a little heavy but just right for such a watch..
I have used it a lot in the sea and water and it doesn't notice anything..
Finally, I didn't believe that with this money I would get such a watch...

This is the "sacred disc plate" of Citizen! Amazing watch, in every aspect, suitable for diving, water activities, and also for tough use. Highly recommended!

The bezel makes a ticking sound, as someone else mentioned in the comments. The strap adapters are definitely needed - they add character. If you can find it in titanium, even better. It's worth its money. This watch demolishes walls, it's a beast!

Very sturdy, heavy, and beautiful watch... I find it very difficult to put on and take off because the strap is incredibly hard... It annoys me that it makes a ticking sound when you touch the bezel around the glass... these are my first impressions..

I had fallen in love with this watch since I was little... 100% masculine watch for those who know how to distinguish the sturdy construction and quality... CITIZEN FOR EVER

If you want a watch for all situations reliable, imposing and more retro purely masculine, you get it with closed eyes!

I don't have much to say about this "beast"! Everything has been mentioned in the previous comments! It is a landmark watch for the diver's category now, with its price (due to its simple and minimalist construction, mainly of the eco drive mechanism) ranging from €200 to €250, it is more than just an opportunity! The only maybe flaw is its hard and inflexible strap! By purchasing (after market) adapters to change different straps and bracelets, it is further upgraded! A watch that truly deserves to be in someone's collection and, by extension, on their wrist!

Excellent watch.. incredible construction. Even if it cost 300€, it would definitely be worth it. My wrist is 20cm and it fits perfectly. The luminescent numbers and hands are amazing (photo).

P.S. for the friend who asked if it can be attached to a bracelet. Yes, it is possible but it requires 2 small accessories that you can attach and then you can use any strap.

The best diving watch at 250 euros that has ever existed.. Very strong construction, stainless steel, and anyone who doesn't see it up close can't understand how much of a beast it is... Maybe even after 100 years, they will still talk about this exceptional piece, the Citizen 300 meters waterproof is one of the few... Bravo to the company for this. Amazing sturdy construction that can truly withstand anything

I had it, sold it, and bought it again because I realized that such a watch should not be missing from my collection

Sturdy and legible.
Bulky but also heavy.
It's not for everyone.
I liked the feel, but I think it gets tiring after a while.
Watches for a lifetime in terms of durability and timeless style.

For its price, it is good. I use it for diving and everyday swimming and it has not presented any problems. The strap is hard and difficult to use. So far, I enjoy it, we will see after three years.

The powerful ProMaster ☆ECOZILLA☆ "Monster" made of Stainless Steel by Citizen, Made in Japan.
Extremely imposing, beastly, masculine waterproof watch at 300m and beyond, it has been tested at over 800m and nothing happened, there is a video on YouTube, so the 300m is purely indicative, incredibly durable among the few on the planet, 6mm High-Strength Mineral Crystal, top-notch phosphorescence at night, Eco-Drive mechanism powered by any light source.
A-M-A-Z-I-N-G!
Watch the video of the Italian technician, he opens it and changes parts, he basically does whatever he wants--->>> https://youtu.be/Sd89UkNImKY
UPDATE-UPDATE 22 - 11 - 2022.
After 2.5 years of continuous use, the accuracy is unbelievable, it hasn't lost any, I haven't had any issues! It is the best thing I have ever worn...BRAVO!!!

One of the best watches I have bought. 6mm glass thickness that looks like a magnifying lens in water. Screw-down crown for added security that fits well at the 9 o'clock position, it also has hacking for greater accuracy in time synchronization. Very visible dial with long-lasting blue lume in the dark. The build quality of the watch is what you would expect from a professional tool, a wrist instrument for diving, so the size is perfect. One of my favorites, it is comfortable to wear everywhere and when you see it, it captivates and excites you to push it to its limits, after all, it is meant for good dives.

Incredibly high-quality construction, serious diving, solar charging, looks good at night, expensive, the crown protrudes and protects the crystal.

I wore it all day every day in the summer at the beach and now while hunting at work, it doesn't get damaged at all!!!
Really wonderful, the downside is that it doesn't go well with a shirt due to its size and it's a bit heavy.
BRAVO CITIZEN

The watch is beautiful, I have had it for a month, it is sturdy and looks very nice on the wrist without being huge. It has phosphorus that lasts all night and allows you to easily read the time in the dark. I highly recommend it, it is an excellent purchase and it is Citizen!!!! It has a very strong metal, withstands impacts, and has impressive details in its design. It is truly something special to wear every day and even during your dives!!! Also, its mechanism is very accurate!!!! In short, a watch for a lifetime! Ecodrive = charging from all light sources, not just the sun!!!!!

Unbelievable watch. I have several watches in my possession, from cheap to quite expensive. This particular watch is the best thing to wear. 6mm glass to withstand hydrostatic pressure, which becomes magnifying lens underwater. Three o-rings for sealing on the crown. Internal bars on the strap for absolute security. Of course, eco drive, so no need to open it for battery replacement. Also, screw-down crown, without any other buttons that reduce waterproofing. Extra strap for diving suit. Appearance and feel for €1000 and above!!! Take this watch with closed eyes, it's just amazing!

This particular watch, especially for the price, is amazing. Such quality could be found in watches over a thousand euros. It is also unusual that it can withstand three hundred meters, as very few watches in this price range are rated for dives of such depth; most are for two hundred meters. The "eco" mechanism is additionally quite useful as it neither loses time nor requires servicing like automatics, and of course, it doesn't need a battery change every two years. A watch for serious divers but also for watch enthusiasts who want a "professional" diving watch in their collection. It is quite large but justifiably so since it is designed for diving. One negative is that the strap is difficult to replace as the watch can only accept the company's exclusive strap. I don't wear it much anymore, but objectively speaking, it is a remarkable watch.

The watch is simply wonderful..... sturdy construction made of steel.... it gives you the feeling that you are wearing an 800 euro watch.... it's a bargain for a watch of this quality.... combined with the eco-drive mechanism that recharges the battery from any light source so you never have to change the battery.... waterproof up to 300 meters, what can I say, a watch for a lifetime.... I highly recommend it to anyone who wants to have a top-notch watch with unlimited battery life and exceptional durability....
