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 double safety clasp, very hard bezel to turn, overall gives you the feeling of a 1000 euro watch. In one month of measurement, it loses + - 1 to 2 seconds, which means the time is + - 10 seconds! One advantage of the ecodrive mechanism is its incredible accuracy, even though it is a very simple mechanism.... I think that Citizen is the only way to go for this price. The only downside is the date display, which is incredibly small.

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

1)... Watches should be purchased in sizes up to 42mm. The ideal size is 40mm. They don't tire your wrist and you can wear them comfortably. I have sold all the ones I have bought over 44mm... This particular one is 44mm, if it was 40mm it would be the perfect watch that exists...
2) Watches that have chronographs and other features besides time and date are unreliable and break down (if you use the chronographs daily, they will break within a year at most)... No matter how much they cost...
3) Do not press buttons underwater, no matter how waterproof they claim to be...
4) IF THE WATCH IS OPENED FOR BATTERY REPLACEMENT, SERVICE, ETC., WATERPROOFING PROBLEMS WILL START...

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

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