One month of use, daily time measurement and comparison with world time, it doesn't seem to have lost a second! Beautiful blue color. It is not heavy on the hand and ideal in size for me (20 cm wrist circumference). It performed well in simple bathing and shallow dives. One small complaint. The bezel has a slight play and mainly "moves" slightly when pressed vertically against the body. My old good watch of another brand did not do this even though it had a certification of only 100 meters and not the accuracy of this specific one. Also, the bracelet seems to easily cause injuries. Overall, I am satisfied, a lover of accuracy (that's what a watch should do and not pretend to be a barometer or make coffee) and that's why I decided to overlook the small flaws in its durability. We'll see.

In the 2 months (approximately), the accuracy remains at the same levels, although I have the feeling that it is actually -0.5 sec/month and not +1/2, as noted in other reviews. However, regardless of the nitpicking, the opinion is established that it is a good purchase, a precise, beautiful, not too heavy/bulky watch. Ideal for everyday use, but requires caution when worn during "hard" work. For its price, it is exceptional.

A jewelry watch. Sturdy, very good bracelet with a double safety clasp, very hard bezel to turn, overall it gives you the feeling of a 1000-euro watch. In one month of use it loses + - 1 to 2 seconds, which means + - 10 seconds a year!!! One of the advantages of Ecodrive mechanisms is the incredible accuracy, although as a mechanism it is very simple.... I think that Citizen at this price is the only way to go.
The only downside is the date display, it is incredibly small...

#Although I am a fan of automatic watches, it is very tiring to correct the time every week. This is a huge advantage of Ecodrive mechanisms, because you can forget to pull the crown for years. I have had the watch for about 1.5 years and it has lost 15 seconds.!!!#

1)... Buy watches with a size of at most 42 mm. The ideal size is 40 mm. They do not tire the wrist and you can wear them comfortably. All the ones I have bought over 44 mm I have sold... This one is 44 mm; if it were 40 mm it would be the perfect watch there is...
2) Watches that, besides time and date, have chronographs etc. are unreliable and break down (if you use the chronographs daily, within a year at most they have broken)... No matter how much they cost....
3) Do not press buttons underwater, مهما many meters of water resistance they have...
4) IF THE WATCH IS OPENED FOR BATTERY CHANGE, SERVICE, ETC., WATERPROOFING PROBLEMS START...

WARNING!!! NO WATCH IS WATERPROOF IN VERY HOT WATER,..

After 2 years without pulling the crown I am at +20 seconds!!!

I see that it has reached 350 euros. I bought it a few years ago for 150 euros, maybe even less.
GUYS, CALM DOWN A BIT OVER THERE AT CITIZEN ...... OK, good mechanism, but not 350 euros. ENOUGH
