  • Built like a tank & worth every penny on sale
Color: Black Strap/Black Dial
The "Ecozilla" (as this model of Citizen watch is informally called) is a big burly beast. The steel case has a 48mm diameter and 19mm height, with a 29mm band width: truly monstrous dimensions. But it's not too heavy given the size and thickness of the case/crystal, so your arm won't drag or leave you complaining too much about the mass (at least in my opinion -- this is subjective of course). The mineral crystal is clear with no significant distortion, but with a thickness of 6mm it's more bulletproof than probably any other watch you own. The unidirectional 60-click bezel is situated entirely within the diameter of the case, so to turn it you must press down from the top rather than grab it by the edge -- a bonus because you're much less likely to move the bezel by accident. The markers, chapter ring and bezel are perfectly aligned, unlike most of the new Seiko divers which have notorious alignment problems (just google "Seiko misalignment" and you'll see what I mean). Citizen's high torque Japanese-made B873 quartz movement oscillates at 32,768Hz and is solar powered with a six-month power reserve when fully charged, and two warning functions, the first indicating low power that doesn't affect timekeeping, and the second indicating low power that does affect time-keeping. Second hand alignment is about 95% perfect around the dial, but literally every Ecozilla I've seen has a few dial positions where the second hand slightly retrogrades off alignment before advancing to the next pip on the chapter ring. This appears to be a consequence of the high torque and very robust movement design, and is not due to loose hands, damage or poor quality control. After all, this watch is rated for saturation diving in a helium-rich environment up to 300m, or almost 1/6 of a mile below the surface of the ocean. Accuracy is rated at +/- 15 seconds/month at 41°-95°F, with an operational temperature range of 14°-140°F, but mine runs only about 3 seconds fast per month. The lume on all three hands, plus the hour markers and bezel 0 index is good -- not as bright as a Seiko but sufficient for diving. The florescent-outlined minute hand is especially highly visible. My only complaint is the common one with many watches these days that don't have a "cyclops" magnifier bubble over the date window: "the date display is too small," which is fairly trivial as it just takes an extra second or two to focus your eyes and read it. With this baby on your wrist you won't have to worry about your watch failing for just about any reason -- it really is the Ecozilla, a solar-powered marine monster dominating all comers! Best of all is when it's on sale for under $200 new. Highly recommended! ... show more

  • Just a great watch!
Color: Black Strap/Black Dial
I was going back and forth whether or not to buy this. The reviews were so positive that I gave it a chance. I am so glad I did, the watch is beautiful and it does not feel too big once on, (my main concern).

  • A big chunk of beautifull, Ecozilla!
Color: Black Strap/Black Dial
This watch blew the wind out of my sails. It surpassed my wildest immagination. Solid solid solid. My best Citizen even beating my Orca.

  • Excellent
Color: Black Strap/Black Dial
I bought this watch in 2017 and purchased a stainless steel band. I have wore it as my everyday watch since. It has been a great performer and fits my large frame. It has been on many adventures in and out of water, snow and everything between. The solar battery is starting to go out started about 3 months ago. Hopefully I can get it replaced. I would definitely purchase again even at the current price. ... show more

  • It's pretty thick.
Color: Black Strap/Black Dial
I just recently invested in this timepiece; its actually pretty nice watch. I will let you know that it is true about what other people mentioned about this, specific timepiece. Yes, it is pretty dang thick! The watch it self, not the strap. It's thick, but not thick thick. It kinda looks like the gravaton; (I hope I spelled it right?!) that ride from the carnival where it spins in circles and people get magnetized on the walls?! Yeah, that's it. So just picture the "Gravaton" on YOUR, wrist, and thats what this watch well look like; just not that big?! I'm a guy who happens to have small arms and wrists; so this watch isn't just for men; it can be for women as well?! This timepiece happens to be heavy as well. Again, not that heavy. Hell, that cellphone you got in your hands right now, is heavier then this watch; so if you cen carry that cellphone of yours everywhere you go, this watch shouldn't be an issue. Mark my words people. I'm telling this as it is; specific, down to the very last detail. This timepiece can be an very day watch. This is how I'm using it. ... show more

  • Love this watch.
Color: Black Strap/Black Dial
Very well made and keeps great time. This watch is as rugged as they come and works for the professional diver just as well for snorkeling. It looks great on the wrist!
