My core watches have been or are turning out to be relatively affordable, fun, and largely Japanese… world time settings (48 cities), 31 time zones, the additional 2 time zones are for the cities of Fernando de Noronha (-2) and Kathmandu (+5.75)All the upgrades are a positive and may be difficult to resist.

The 5000U is sound and satisfying. Whether I'm sat at my desk, out walking, going to the store, driving, airports, desert, forest, ocean, whatever, it's wonderfully constant. You can get it wet, covered in dirt or sawdust or sand, bang it, drop it, leave it outside on the lawn all night - and it'll just keep on doing what it does flawlessly. And for those who know about watches, it has a fascinating heritage and design ethos. Individualistic. Retro chic. Tough. Bullet-proof reliability. Now with the light setting on 3 seconds and the brighter LED I found that could read it in the dark quite easily and the optional DD:MM format also helps legibility. Technical amendments and errors excepted. The sizes in figures do not correspond to the original sizes.Adjustable date format (M.DD or DD.M) and adjustable day of week language (English, Spanish, French, German, Italian, Russian) Invisible solar cells in the watch convert light into energy and supply all functions. A rechargeable battery provides the necessary capacity for operation in poor light conditions. Whether in Europe, North America and Japan or in the outer reaches of Canada, Central America and China - once the watch has been set to the local time, it receives the relevant signal and shows the correct time wherever you are. In many countries, it also sets itself automatically to summer and winter time.

Perfect for free diving without scuba gear: the watch is water resistant up to 20 bar according to ISO 22810. Yep. Totally. Though, whilst you are technically correct, these sort of changes can double, triple, and quadruple the price of this style of watch. That is, in terms of how Casio typically places things like sapphire, titanium, STN etc in higher models. So, that kinda moves it out of the "classic square" category for me.Elapsed time, split time and final time are measured with 1/100-sec accuracy. The watch can measure times of up to 24 hours. It’s clear from your post that you want a GW-5000U, and I am a big proponent of getting what you want in life. Home city time and world time display swap in world time mode by pressing the top two buttons (A and B) at the same time

The daily alarm reminds you about recurring events with an acoustic signal at the time you have set. This model has 5 independent alarms for flexible reminders of important appointments. Then the new ‘U’ version came out and I bought the GW-5610U discounted to see if the changes made any real difference. You see, I like flying under the radar as far as my watches are concerned. I have no need or want to own and show off the flashiest wrist candy available. My flashiest watch is a Mr Jones Watches Nuage, which is only so because it’s immediately apparent that it’s a watch that is not for telling time. That watch is also on my special list of four, at least until I get a chance to get out to Japan and shop for a vintage Seiko to replace it as my go-to “dress” watch. Another watch I already own that’s on the list is my Seiko Alpinist SARB017, my GADA three-hander. See a trend? I do. My core watches have been or are turning out to be relatively affordable, fun, and largely Japanese (though the Nuage employs a Swiss quartz engine). That won’t be the case for the final addition to the four, though that’s a topic for another article. For fans of precision: the countdown timers help you to remember specific or recurring events by giving off an audible signal at a preset time. The time can be set to the nearest minute and up to 24 hours in advance. Ideal for people who need to take medicines every day or those who do interval training. Synthetic resin is the ideal material for wrist straps thanks to its extremely durable and flexible properties.The latest upgrade comes with some long asked-for changes, albeit pared to the core. Yet it also retains some of the best features of the original: the same dirt-cheap replacement bezel and strap that have been made for the past 10 years. DLC to resist scratches. Its shares the same module as non-steel watches that have been produced in far greater numbers, so replacements and spares are virtually guaranteed.
