I've had it for 10 years and I have no words. Comfortable on the wrist, you don't even notice you're wearing it. Since it charges from the Sun, you forget about battery changes and servicing. I don't think I'll ever service it, even though I read it needs it every 3-4 years for lubrication of the mechanical parts. It has a screw-down crown, so you don't have to worry about moisture getting in. The size is ideal for those with a thin wrist. The luminous markers still shine like the first day. The only downside is the plastic strap, which fades over the years, which is completely logical. I highly recommend it!

The second eco drive I have bought. Subjective, but I like it aesthetically, trouble-free in operation, and suitable for heavy use. The first one I bought I have had for 12 years and it works perfectly without service. 1 star - because the strap broke and the replacement costs 49 euros.
Update 11/2025 and the second one broke after a year and a half, so apparently the design or the material is not durable. I am looking for a solution
And I will not buy the original again, but if someone wants the look, it has a high cost that is not proportional to the category of the watch.

I have it for several months. It is beautiful, ideal for diving, and very lightweight, does not tire the hand. And from a company that produces watches.

Perhaps the most must-have diver watch for all collections. The expression VFM is not enough to describe this promaster, Excalibur name and thing, you enjoy seeing the wonderful blue-turquoise lume that lasts for hours. Maybe some will say why it doesn't have a sapphire crystal even though there is no reason to prevent you from buying it, the 60-click bezel is wonderfully functional, the strap is very comfortable (why, Citizen, 23mm?), maybe the dial color could have been a little darker and I think Citizen should have released it in other color variations. Recommended with closed eyes, just like that!

Very good build quality.
Awesome performance in the dark. The only observation is that the excess of the strap easily comes off the loops, they should be tighter.

Update 2025
Still working flawlessly!
Synchronized with PC time and the loss per month is not noticable.

Excellent quality comparable to CITIZEN. The quality of the strap is relatively good compared to other models in the CITIZEN diving watch series

This is the CITIZEN BN0100-51E (which was also available on SKROUTZ in the past), but with a strap instead of a metal bracelet. It is the exact same watch!! It is also called "EXCALIBUR" because of the sword-shaped hands it has! The outer rotating bezel has 60 clicks instead of 120. It looks somewhat big on the wrist, especially on a thin wrist, but maybe it's just a matter of getting used to it.

In the dark, you can easily read the time (so easily that you almost wonder!) and definitely from night until morning!! The mechanism is undoubtedly reliable. The crown is screw-down with a shallow screwing depth. It has "Eco Drive," which means a battery that is recharged by solar or artificial light and has a very long lifespan (+- 10-12 years)!!! It has ISO 764 certification (magnetic protection), which means that the mechanism is protected if exposed to magnetic fields! IT DEFINITELY DOES NOT GO UNNOTICED!!

Classic watch from Citizen. It's worth its money multiple times. You wear it and forget about it! Especially useful for those involved in activities with the sea or water in general. I highly recommend it, especially at such an attractive price.

I have a smartwatch, but when I wear this particular one, it's a different class... Solid heavy stainless steel.. (sometimes my wrist hurts haha)... The watch is amazing.. Tremendous construction in every detail, I've had it for six months and it doesn't lose a second..
It's 42mm, I think it's the ideal size.. I wore it to the beach once this year for exploration.. it was okay!!
In a few words, it's a different class and a great watch, you enjoy wearing it

I have been using the watch with the bracelet version for 6 years now. The problem I encountered, at least with mine, is that the crown was unscrewing very easily no matter how tight I screwed it. As a result, it opened when I was underwater diving. The watch went to Citizen's service where we managed to fit a crown similar to the aqualung jp. It was aesthetically and functionally upgraded.

The watch is worth every euro, you can buy it with closed eyes. Citizen quality without issues in its solar function and of course in its diving capabilities.

The cheapest ecodrive with resistance to 20 atm. Solid construction and also with the smallest dimensions compared to others. It has nothing to envy from other similar and slightly more expensive ones from Citizen. Perhaps the others may be worn more beautifully on the wrist. However, I chose it because of its size, as being the smallest in its category, it was the most convenient on my wrist.

Truly a value for money watch from Citizen. It looks more expensive and high-quality with the brushed stainless steel. I chose the version with the rubber strap and added a quality NATO strap. The bracelet itself is also of good quality for its price. Screw-down crown and a 60-click unidirectional bezel for diving. Great accuracy in timekeeping and strong lume that lasts all night. Very comfortable and I think the size is ideal for divers.
