Resin is made of synthetic resin and is the ideal material for bracelets due to its extreme durability and flexibility. The daily alarm reminds you of daily recurring events, in which an acoustic signal is emitted at the set time. In addition, a switchable alarm draws attention to the expiry of each hour. This model has five independent alarms - especially convenient for taking medication on a daily basis or keeping regular appointments. The time display can be set to 12- or 24-hour format. In 12-hour mode, a p is displayed for the second half of the day, i.e. 12 noon to 11:59 p.m. For the more down to earth, and more true to the original, resin models, the GW-M5610U with its new 3495 module is the first one to offer switchable DD/MM and MM/DD date notations. As a bonus, the DD day abbreviation can be set to six languages, English, Spanish, French, German, Italian, and Russian. The former model only had English as an option. World-time

For me, its great for going out for a few hours but overall the 5000u is better suited as an "all the time" watch. Or, at least as Bob Dylan once sang, “Most of the time”… Perfect for free diving without scuba gear: the watch is water resistant up to 20 bar according to ISO 22810. The feature of permanent displaying the home time sacrificed the stopwatch somewhat. It still runs to a maximum of 23 hours, 59 minutes, and 59 seconds, but the old module offered 1/100 of a second for the full maximum duration of the stopwatch. With the new module, 1/100 of a second is only available for the first hour (59′ 59” 99”’), thereafter the maximum accuracy is one second. For me, the permanent availability of the time in the display is way more usable. Alarms and TimerThe button tones for using the mode button can be turned off. This means that the watch no longer beeps when switching from one function to another. Preset alarm or countdown timers remain active when the button tones are deactivated. 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.

Elapsed time, split time and final time are measured with 1/100-sec accuracy. The watch can measure times of up to 24 hours. Adjustable 1.5 or 3 second afterglow for light (versus 1.5 second non-adjustable afterglow on module 3159) Functionally, the 5610u matches it. However, the visceral experience of putting on the 5000u after wearing the 5610 feels like step up in class. The all-metal B5000 has a few extras like Bluetooth connectivity and short reminder message possibilites but that may even be a negative for some. Likewise with its weight. Perfect for freediving without equipment: the watch is water resistant to 20 bar / 200 meters. The meter specification does not refer to a diving depth, but to the air pressure, which was applied as part of the watertightness test. (ISO 2281) If desired, the key tones can be switched off with the mode button. After switching off, there is no longer a beep when switching from one function to the next. Set alarms or countdown timers are still active after the key doors have been switched off.Adjustable date format (M.DD or DD.M) and adjustable day of week language (English, Spanish, French, German, Italian, Russian)

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 For those who want to know exactly: The countdown timer helps to remember special or recurring events by emitting an acoustic signal at the set time. The time can be set every minute and up to 24 hours in advance. This function is especially convenient for daily medication or interval training.

Model Comparison

I then went with the GW-5600 that linked through to my iPhone which I quite liked - but I still hankered after the simplicity of the self contained GW-5000.

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. 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. A reliable source has a new “Speed Model Series” listed for July 2021 in Japan. Though not all of the details are available, it includes three GW-M5610U models, one GW-5000U, one GW-S5600U, and one G-5600U.Weight wise, it is, unsurprisingly, the heaviest of the bunch at 154gm - over double the weight of 5000u and triple the weight of the 5610u. That puts it firmly into steel diver's watch territory in terms of wrist presence. Some may feel this is a desirable or less desirable thing depending on use case and preference. For athletes and all those who want to know exactly: Elapsed time, split time and end time are measured with an accuracy of hundredths of a second. The measuring capacity of the watch lasts up to 24 hours. Independent and environmentally friendly, solar cells provide the power supply for the watch. Excess solar energy is stored in a rechargeable battery.
