Ecozilla, big heavy and incredibly well made.
I also bought a Rotary watch for similar money, both this and the Rotary are Dive watches, but this is far superior in terms of build quality and luminescents. It is a big watch, well huge, so not a dress watch as it's thick and heavy and the strap is very stiff, but it's actually very comfortable to wear (and I don't have big wrists). This watch is a bit of a collector's piece, as well as a fantastic watch to wear, and at circa £230, it's a really good price. It came well packaged in a scuba tank "box" and it is a watch you'll love to own.

The eco-zilla, boy oh boy is this thing a chunk!
I received my watch today. First and foremost, its a 'watch'. A watch the size of a small planet, but nonetheless still just a watch. It has no chronometer on it, nor a barometer, nor even an altimeter. But you are not buying a Casio here, I suspect if you buy this watch you already decided that you aren't bothered about bells and whistles. It tells you the time and date, glows like a neutron star in the dark, and doubles up as a blunt-force object if you are ever caught in a tricky spot against some big lads sporting tattoos and steel cap boots. You can also wear it in a cat5 hurricane and not worry about it failing on you. Its a tool watch, and it serves that purpose in droves. Plus it looks DAMN good. Its a watch that serves as ego-food for those who want everyone ELSE to know what they are wearing. This will just keep going, and going, and ... well, you get the point. And you can dive with it, it has ISO certified water resistance down to 300m/1000ft. The extension strap for wearing the watch over a dive suit, or a big thick Shetland wool jumper, is a welcome addition. Packaging is nice, the black box with silver trim instantly tells you you bought a watch that your neighbour never even realised existed, let alone might be sitting on his mantelpiece. This is an eco-drive, so works on both indoor and outdoor light. It supposedly has a 180 day reserve when full, so shouldn't ever run out of juice with normal use. I suspect this might just be the last watch I will 'need' for quite some time. Desire is another matter, but I wont have a material need for a working watch because I suspect this will be on my wrist in 10yrs time still going like a beast. The date is a little small, but that seems to be the trend in dive watches. If I need the date its on my smartphone or the TV guide, so its not a dealbreaker at all. Its not so small that you cant see it with a little prolonged focus, or with reading glasses. There is talk of how uncomfortable the strap is. Myself, it seems fine. Not uncomfortable at all. No more than any other rubber strapped watch I have. I will probably get the suppaparts or citi adaptors, in case I decide a NATO strap is the way to go in the future. Right now im blissed out that it is on my wrist in person, a big smile on my face. This watch is no joke, its a total monster. A very worthwhile purchase. UPDATE- Three weeks in, this might just be the most accurate watch i've ever seen. I set it by BBCNews when I got it, and its not lost or gained a single second. Not ONE! Unbelievable. Every hour BBCNews hits the hour, and the EcoZilla matches it to the tick. Incredible watch, BUY! I doubt a £2000 watch would match it for accuracy

I received the watch in a cardboard box not a peli case or dive cylinder- diss appointed
What a watch! Very heavy but I am used to chunky G Shocks so not a problem. The lume lights the bedroom up and lasts all night! I. Look forward to diving with it and looking at the build quality it will last years and probably even an earthquake. The only negative point I have and it’s worth being aware of is, I received the watch in a Citizen cardboard watch box, not the waterproof ‘peli’ box or miniature dive cylinder as other people have so maybe a note to Amazon to make people aware in the advert how the watch will be presented after purchasing it. So I was disappointed. But over all if you don’t mind the weight of it and the size then snap one up as it’s a classic timepiece that will last for years!

Not for everyone but...
I first saw this watch 12 or more years ago. I’ve always wanted to own it. I was amazed to see it appear on Amazon during some browsing. I really had to question whether it could be new. It doesn’t appear on the Citizen website with the exception of Germany. When mine turned up it was from Germany but had come from a supplier in France. The watch is perfect and definitely new. I’ve read critical reviews and some seem justified. If you see that the labels are in German you might expect it to be original and new. If you like robust purposeful watches, it doesn’t get better than the ‘Ecozilla’. It has become the daily wear. It is heavy and the strap isn’t the most comfortable but I can’t say it bothers me overly. Can’t believe I managed to get one after all this time.

Beware!
Buy at your own risk! Arrived solar movement not working, wouldn't hold charge. Lacking original quality of packing expected by Citizen product. As others have highlighted, I sense these are castoffs from the factory with quality control issues at production. Returned for refund.

Great watch overall, except...
There's a fair chance that you have seen a number of YouTube reviews of this Ecozilla watch so I won't be reiterating what people say there - as it's a very straightforward watch and what you see is what you get: usual Citizen quality and durability, plus its bulky size. There's something that Citizen could improve though and this is why I've knocked off a star. First of all - why Citizen is so stingy about adding the day of the week to their watches, especially more expensive ones like this Ecozilla? Seiko does it on their much cheaper timepieces, so it's not a manufacturing cost issue here, and for someone who's self-employed I would really appreciate seeing what day of the week it is. Second thing - and the biggest and most painful one of these two - is its strap. Thick, uncomfortable and painful to wear. Even though you somewhat get used to it with time - it never comfortably embraces your wrist and always reminds you that it's there with those upper creases that are designed to dig into your wetsuit sleeve but dig into your wrist instead. I do understand that its primary purpose is to serve professional divers, but the absence of a more comfortable bracelet or silicone band severely limits its usage in one's daily life. Do Ecozilla creators expect people to use this watch only on their diving trips and then put this watch away until their next dive? I'd guess 99% of Ecozilla owners wear it in their daily lives, and this strap is simply not created for that. Granted, you can buy strap adapters which I have done by ordering a £60 set, which not only allows to use a bracelet/band of your choice, but also transforms its looks for the better - something that at this price Citizen could have done themselves. So yes, great watch but needs more thought and convenience for customers.

THE ULTiMATE iN CLASSiC BiG HONKiN ULTRA COOL DiVERS: THE HOCKEY PUCK
i've wanted one of these for a long time, and it may have satisfied my need for any more watches. admittedly, i've already purchased some 50 amazing dive watches, so that's part of the reason, but this is such a satisfying 'hockey puck' (as it's called) for someone in love with giant legit dive watches, that it may be all i've ever needed. and if that's your thing, maybe you too. as a review, we already know it's huge, however because of there being no lugs, it wears shockingly well for such a huge watch (i'm a 7" wrist). while heavy and 18mm thick, it balances and sits quite well, if that's a concern. as for everything else, it's all good (as they say). no bezel alignment issues with this or any Citizen as with one other infamous Japanese powerhouse brand. in fact everything is superbly and accurately built and put together. the lume is stunning and equal to first class anywhere. the bezel is what diver nuts dream about: locked in, no backplay, perfectly aligned. that strap is a stiff one, like none other. but since this is foremost a world class diver, the strap qualifies as that and will after a half-dozen wearings conform to your wrist as if molded. personally i love the slight dome on the crystal, and in true diver fashion it is mineral glass to prevent shattering for use as a pro-diver. the bezel is one of the most enjoyable to dial, and even the 60 clicks are a joy...who needs 120. the only issue i should mention is one common to all quartz: the secs hand hitting the markers right on. after fully charged i've found it does one of the better quartz movement jobs of nailing markers...this one hitting right on virtually 100% of the time after a day of being charged (was hitting a little off, but after more of a charge it's amazing). Citizen is one of the best in this dept, tho i did need to return one of these (the yellow strap) a year ago over that issue. thankfully that wasn't the case here as i fell in love with this out the box. speaking of which, given that this was first offered in 2013, it's truly 'vintage'. not sure when this one was made, but it barely had a charge from being in the box. once sunlight hit it, it have a 2sec/2single sec movement, which means it had totally lost it's charge. after research i found when that happens, to charge it with the crown fully out for at least a minute, then if wanted you can keep charging with it in. that tells the watch to reset, and it will begin going in the normal undercharged 2sec intervals. at that point it was so low it took 10 hours under a fluorescent light to get to one sec intervals, and another few hours as well to hit the markers spot on. i've found that with solar watches, if they're low charged, even if not 2sec intervaling, they tend to be slightly less accurate on the markers (clearly an issue with me). Citizens are scads better at quartz/marker accuracy than that other Japanese maker, but the only quartz watches i've found to literally nail the markers with the sec hand are very high end: the $600 Citizen satellite controlled solar diver and the $1800 ($2700 retail) solar diver...both of which i have. do note, i love this $325 Citizen every bit as much as those, and it indeed has just as much wrist presence or more.

Unico...crea dipendenza
Parto dalla parte negativa: mi è stato consegnato in una semplicissima scatoletta di cartone, poi è fermo, quindi va messo sotto una luce potente ,prima inizia a scattare ogni due secondi e poi va a regime. Mi aspettavo il quadrante più grande che invece è un po' piccolino soprattutto per uno che non vede niente come me. E ora il resto, possiedo una trentina di orologi da Omega a Rolex a quelli giganteschi dell'invicta visto che mi piacciono i patacconi, ma questo lo fa sparire tutti., Come dicevo non è così grande ma allo stesso tempo dà un'idea di forza e resistenza che ho mai visto in un orologio , mi viene voglia di toccarlo continuamente ,sembra lo scafandro di un palombaro, una piccola opera d'arte.il cinghino È particolarmente rigido ma fa coppia con l'orologio che ripeto non vedo l'ora al mattino di indossarlo. È talmente pazzesco che anche mentre lavoro continuo a guardarlo e fissarlo , una vera e propria opera d'arte con una capacità costruttiva che lo rende forse il miglior orologio subacqueo al mondo. Non so come si potrà cambiare il cinghino perché esso sembra scomparire nell'orologio, ma ne preoccuperò se e quando succederà. Chiudo: il più orologio che abbia mai visto
