Who is this BJ8050-08e for?

The big question of who is this watch for? Is a question that has to be asked for any product that is built? But basically, this product can be used by serious divers, as they should really consider using this watch as it boasts a 300m water-resistant and a screwed-down crown. Apart from its water-resistant feature, that big bulky case would surely give the watch some kind of protection against any drop or impact while diving.

Even though you are not divers, and you do not swim, this watch can still be for you as it really looks great on casual wears, so you can totally use them for any casual outing. Also, anyone who loves a visually attractive and unique watch on his wrist can definitely still go for the Citizen EcoZilla BJ8050-08e. Because of the huge size and weight, this watch gives the wrist a presence.

Key Features/Benefits

Casing Size

The case of the Citizen EcoZilla BJ8050-08e has a huge 48mm diameter, and when compared to other wristwatches, it reveals that the EcoZilla is bigger.  A most normal classic dress watch is usually about 38mm in diameter which is less by 10mm when compared with the EcoZilla.

With this size of the EcoZilla BJ8050-08e, Citizen actually pushed it beyond the boundary of how huge a watch can be and not just the diameter, but also the thickness is about 18mm which is also astounding.

The EcoZilla BJ8050-08e from Citizen is a monstrous watch that has a very nice heavyweight to it. While also the Stainless Steel casing also makes it look more rugged and a watch that is intended for actual diving. Also,

This little beast can actually get down to as low as 300m beneath the water and still be working perfectly fine; this is because of the well-compacted casing of the watch as it can actually resist water, which means you can actually dive with this watch.

Many times when you get to the store you would find a lot of watches that have the divers look, but cannot be really used for diving. So basically, the EcoZilla BJ8050-08e is actually watch meant for people who love having a big manly looking watch that is if you have the wrist for it, and bear in mind that it would actually feel heavy.

Case design

Because of the size of the EcoZilla BJ8050-08e, Citizen decided to use a lug-less case design which makes the watch totally circular in shape. If not, the watch would have been very big and only people with very big wrist would have been able to rock this wristwatch. A bit thanks to Citizen for this lug-less design.

Sad to say but this special lug-less design actually means that the polyurethane watch strap is specially built for the watch with separate metal coupling to the case. And this means that the watch strap cannot be changed without purchasing a separate adapter to connect it to the back case.


The EcoZilla BJ8050-08e bezel is raised pronouncedly to give the mineral crystal on top of the watch good protection. This is quite important because mineral crystals do not really look all that nice after it has been scratched.

How to rotate the bezel is a design I do not really like about the watch, as you would need to grab ghetto bezel from the top because the side of the bezel is a protective ring which is not connected to it.

This design actually makes the bezel not so natural and a bit difficult to rotate. It is actually really different from the normal divers watch that bezel that can be easily rotated by grabbing the sides of the bezel.


The crown of the EcoZilla BJ8050-08e is screwed down at the right-hand side of the watch that is at 9 o’clock which is quite different from the normal wristwatches which are usually located at 3 o’clock. A lot of people do not like this as it can be a bit of a challenge to use it especially if you are wearing the watch on your left hand.

But to me, I do not have an issue with this because normally we are not meant to change the time on the watch while wearing it, because this is the weakest point for the watch. Any slight bad push can actually snap the crown steam which connects the crown to the inside movement. So it is only advisable that you take off your wristwatch before setting the time


Also, the dial of the EcoZilla BJ8050-08e is black, and in my opinion is a bit too small for its larger case. If you take a close look at the watch, it does not have a good proportion of the case diameter to the dial diameter. To me it is a flaw in the making of this watch; it just looks like a big man with a small head. I’d only advise that Citizen makes the dial a bit bigger in case of any future update.

Also, just like the divers watch you can find everywhere these days, the hand and the marker features a lume. Actually, the hands and the markers are quite bigger than the hands and markers of most divers watch, and the markers are uniquely shaped, as they are neither rectangular nor circular, but are kind of like an elongated half circle.

Also, at the right of the dial, features a date display window, but they are a bit too small and I am sure a lot of people would have a bit of an issue seeing it. Apart from the luxurious use of the lume on the hands and the markers, the lume will surely give a long and satisfying glow in the dark effect.


The EcoZilla BJ8050-08e is also powered by the Eco-drive technology, which is citizen most famous reliable Solar powered movements. And we cannot deny the benefits of the solar-powered movement, as it makes any wristwatch free from the dreading dead battery.

All you need do is just to expose the watch to enough light, and as we already know, the brighter the light the more it recharges itself. And it also has a good 180 days lifespan reserve after a proper charge and I am quite sure that before the end of this period, you would be able to a few good hours of sunlight on it.
