which is why i love gshocks, both for design but also specifically the ones with tough solar/multiband 6 (and bluetooth (optional))
they have battery lives in the range of decades (due to solar charging), set themselves (multiband 6 is using atomic clock radio signals) and via bluetooth
you can get gw-b5600-2 and gw-s5600u (auto backlight) for under $200, but usually closer to $100. there are many more models, of course
that sounds expensive, but it's insanely durable construction and battery life means it'll be the only digital watch you'll ever need to buy. and the only configuration it will ever need is the time zone.
Regular batteries may be a better deal but that doesn't include the process of opening the watch, replacing the battery, and then resealing the case.
I'll trade $15 and a 15 minute job once every 15 years for a 15 minute job every 5 years. And no watch with a regular battery will have auto-backlight (for the obvious reason).
And also... if you want a deal, don't buy a $100 watch with auto backlight, capable of setting its own time off of a radio, and capable of ringing your phone when you can't find it.
F91W will do! That's why they're so popular!

For example, there is a "text removal" option on this one: https://www.nocturnaltime.com/shop/p/obsidian-casio-watch-ws...
You should compare this with the F-91W that gets 7 years on the same battery, and hobbyist hardware mods that get years out of the same battery running ARM chips.
My little temperature and humidity sensors that show an LCD 2x the surface area of a watch and broadcast a BLE packet every minute lasts about 12 months on a CR2032 (~200mah). A CR2016 is ~90mah little less than half. And receiving a BLE packet takes way less energy than sending.
Then you have the on-demand stuff that costs a packet or two, like the lost phone finder -- which is what I'm most excited about.
Though, the CR2016 is a pretty big battery vs typical watch batteries, and in some other Casio watches are used as 10-year batteries.
However, the manual recommends to be sparing with the backlight.
I got one earlier this year, pretty awesome project!
I haven’t worn wristwatch anymore, since the dawn of smart phones. All my time information has moved into that, in my pocket. That’s my only dependency.
I see and I was wondering why they sold it for £55 only. They collect and sell your personal data.
I'm happy with my original one, thanks.
> In a handful of cases the detainee's possession of a Casio watch or the wearing olive-drab clothing is cited as evidence that the detainee is an enemy combatant. No basis is given to explain why such evidence makes the detainee an enemy combatant.
This is also noted on the F-91W's Wikipedia page:

AQ training/bomb-making manuals from the 1990s–2000s recommend cheap, reliable digital watches like this as timers for IEDs as they're extremely inexpensive and widely available worldwide, durable, water resistant, and easy to modify as delay timers.
Often these guys would get picked up with two or more watches of the same model, for example. We recovered them in bomb-making facilities and on fighters throughout the GWOT. Ramzi Yousef (Philippine Airlines Flight 434) and Ahmed Ressam (the 'Millennium Bomber') both had them.
https://en.wikipedia.org/wiki/Khalid_El-Masri
> Khaled El-Masri is a German, Lebanese and French citizen who was mistakenly abducted by the Macedonian police in 2003, and handed over to the U.S. Central Intelligence Agency (CIA).
> While in CIA custody, he was flown to Afghanistan, where he was held at a black site and routinely interrogated, beaten, strip-searched, raped, and subjected to other forms of torture.
> After El-Masri held hunger strikes, and was detained for four months in the "Salt Pit", the CIA admitted his arrest was a mistake and released him.
Trick question! It was actually that his name is one letter away from someone else's name, and some manager in the CIA had "a hunch":
> At the end of 2003, El-Masri travelled from his home in Ulm to go on a short vacation in Skopje. He was detained by Macedonian border officials on 31 December 2003, because his name was identical (except for variations in Roman transliteration) to that of Khalid al-Masri, who was being sought as an alleged mentor to the al-Qaeda Hamburg cell, and because of suspicion that El-Masri's German passport was a forgery.
> CIA agents discussed whether to remove El-Masri from Macedonia through an extraordinary rendition. The decision to do so was made by the head of the al Qaeda division of the CIA's Counter-Terrorism Center, Alfreda Frances Bikowsky, on the basis of "a hunch" that El-Masri was involved in terrorism; his name was similar to suspected terrorist Khalid al-Masri.
> When the Macedonian officials released El-Masri on 23 January 2004, American security officers immediately kidnapped him. El-Masri later described them as members of a "black snatch team." They beat him and sedated him for transport using a rectal suppository. "The CIA stripped, hooded, shackled and sodomized el-Masri with a suppository—in CIA parlance, subjected him to "capture shock"—as Macedonian officials stood by."
This is like a statistics 101 question. Google says that Casio has sold over 100M F-91W's since 1989. Let's round down to an average of 2.5M a year, or 25M over the 10 peak years of the global war on terror (GWOT).
You named two terrorists who wore them. Let's say that's an understatement by 200X. Some quick math shows that the percent of terrorists who wore F-91W's is 400/25000000 = 0.0016% positive rate, or conversely a 99.9984% false positive rate. Not good!
Now I never actually took a statistics class, so maybe I got this question wrong. But it's obvious that using the possession of an F-91W as a sign of being a terrorist is a mistake.
(they did have one called "pickup")
Or more recently, to some officials, showing up at a No Kings rally.
No they don't, please don't spread misinformation. If this were true, the watch itself would be banned in the country and/or nobody would sell it.
Your own source says the Pentagon refuted the author's claims because they did not have access to classified information, which I believe would suggest that there is more to the story than merely owning a very common watch and nothing else. Otherwise millions of innocent Americans would be in jail.
There is a very, very good reason this was only "in a handful of cases" and never again.
I have seen (Xiaomi) smartwatches that wont allow setting the time without an app (asking to many permissions, and forcing cloud accounts) installed on a linked phone. facepalm
