CitizenPromaster Dive Eco-Drive Watch, 3-Hand Date, ISO Certified, Luminous Hands and Markers, Rotating Bezel

Overall, one of the best pieces of work gear I have ever invested in, for my line of work.I am a swimming pool technician, a pool guy, and have been for the last 10 years of my life. I work for one of the largest pool maintenance companies in SoCal and am now a Route Manager, overseeing over 800 individual pools.My everyday has and still consists of many different jobs.Cleaning swimming pools, where I am CONSTANTLY submerging my hands in chlorinated and salinated (salt) water, which does have a corrosive and/or oxidative effect on certain metals.Interacting hands-on with different corrosive and oxidizing chemicals, all of which gets on my hands and wrists at some point everyday.Maintaining, cleaning, and repairing various pumps, filters, plumbing, heaters, automation/electrical pool systems, and valves. This frequently places my hands in uncomfortable, tight spaces where I will bang, scrape, and smash my watches against concrete, metal, and other hard materials in the equipment areas I am working in.I have worn this watch every weekday for the last 5 years for this job. I replaced the original rubberized strap for a nylon/cotton blend NATO strap so it would dry quickly and breathe better. The watch face paint has stood up very well considering how rough my job is on it, with what would be considered as understandable wear and tear. And in my opinion, it gives a worked-in quality of character to the watch.The crystal itself has a few MINOR scratches, which I’m surprised hasn’t cracked or been marred even further, given that I have truly had it banged around hard in my line of work. None of these scratches affect the readability of the watch face at all. You actually have to look in an angled reflection to notice them.The lume of the glowing hands and digits are still VERY strong and last a pretty dang long time. I’m in the sun all day long and so the glow lume gets charged like crazy all day, then lasts for hours into the night.I can also say with certainty that I have NEVER had a battery issue, being that it’s an Eco-Drive and it gets a full belly of sun every working day, I’m not surprised at all. I don’t know when it will ever need a power cell replacement, but it's probably going to be a WHILE being that my line of work puts it in a recharging state at all times.Lastly, the steel body of the watch itself is as solid as when it arrived. It does have some scratch marks, but no gouges. And just in the last 6 months or so, a very light showing of rust-colored oxidization has been showing on the inside of the bezels. I’m surprised its taken THIS long to finally show some signs of oxidizing with how often its been scratched and banged, then plunged into salt and chlorine water and exposed to various chemicals.Overall, I am very pleased with the performance and durability of this watch. In a job where I quickly go through footwear, shorts/pants, sunglasses, hats, multitools/knives/handtools, and other pieces of gear, this watch has stood out as the most rugged and long lasting piece of gear I have bought for my job. I have no doubt it will last a further 5 years easily in the exact same conditions, especially if I give a light polishing for any oxidized areas (which I still haven’t yet).Highly recommend this watch for someone looking for a durable timepiece that can take a beating and still look classy and handsome. I also highly recommend switching to a NATO strap for an even more secure retention (watch won't fall off your wrist if one of the strap bars breaks or pops out).

Every so often, I come across a product that works so well, that suits my needs so perfectly, I can’t imagine being without the item. When this happens, the old military adage, “two is one, one is none” comes to mind, so I pick up a spare. This is exactly what happened when I purchased and wore Citizen’s Eco-Drive Promaster Diver.Adventure awaits you each day when you strap the Promaster on your wrist. With an ISO-certified 200 meter water resistance, this Citizen can handle whatever you throw at it. While most of these watches will probably never see water outside of the sink or an occasional trip to the swimming pool, I have proudly worn the Citizen Promaster Diver fresh water SCUBA diving, snorkeling, and while swimming in lakes. The screw-down crown and well build stainless steel case make this watch more waterproof and shockproof than I would ever need, and that’s a beautiful thing.The ink-black dial on the watch draws you in, like gazing into the deep abyss of the sea. The shiny black aluminum 60 click uni-directional bezel is attractive, and doesn’t have any play or wiggling back and forth. The hour indices are lumed, and outlined with a shiny silver boarder. The syringe style hour hand is outlined in an attractive silver metal, and the arrow style minute hand is outlined in dark orange, allowing you to immediately distinguish the difference, and quickly tell the time. The all while second hand is thin, and unobtrusive as it dances around the dial. The date window is framed in white, and is located at the 4 o’clock position, perfectly aligned with the crown, which pleases my eye.Speaking of the crown, this was the first watch I owned that has the crown at the 4 o’clock position rather than at the 3 o’clock, and I must admit, I am a big fan. I spend more time than I care to admit tripping over things. Stairs, rocks on trails, cleats on boat docks, children’s toys on the floor where I least expect them…my hands and wrists stop me from hitting the ground at least once a day. When I wear a watch with the crown at 3:00, I am often rewarded with pain when that crown jabs into the back of my hand. I simply don’t have that problem with the crown placed at 4:00!The strap that comes with the watch is fine, and works well for diving. Many people will not see a need to change straps, but the neutral design of the watch makes it a strap monster, meaning that it looks good with whatever you put on it. I am a big fan of NATO style nylon straps, and rotate through different colors depending on my outfit or my mood.This watch is extremely accurate. I own several watches with Citizen’s Eco-Drive movement, and there are several reasons that I keep coming back for more. This watch is as accurate as any quartz watch I have ever owned. I reset my watches when Daylight Savings Time comes and goes, and this watch is never off more than a few seconds from when I set it six months before. Unlike most other quartz watches, the Eco-Drive movement is solar powered, and does an amazing job. With this watch, you don’t have to worry about changing batteries every year or two. Wearing this watch outside for one day a week is enough to keep it “charged” up and ready to go. If you store the watch on top of a dresser where it gets some sunlight, you won’t ever have to worry about the power reserve. If you are like me and wear watches on rotation, this Eco-Drive powered watch will work for you. On a full charge, you can store the watch in a dark drawer for more than 6 months without it missing a beat. Simply wear it in the sun for a few days or leave it under a lamp to charge back up.The lume on the Citizen Promaster Diver is impressive. When “charged” with a bright light (like the light on my phone) it will glow intensely for about five minutes, then fade to a level where you can read the time in darkened for about six hours.I love this watch, it and its blue dial brother are on my wrist at least four days a week. If you are looking for an affordable watch that will work flawlessly wherever life’s adventures may take you…look no further. This is the watch for you.
