probably just assembler for whatever microcontroller drives it, probably something very simple like a PIC or indigenous Casio equivalent

...

Allah's will.

It's likely all done in hardware. A microcontroller is overkill for a watch even today and they were bigger,more expensive, and a lot more power hungry in the 80s.

Start with a crystal oscillator at some frequency that can be easily divided down to seconds. Divide down with binary counters (D-flip flops in sequence). More counters for minutes, hours, days. A bunch of AND,and OR gates to get the appropriate 7-segment digits to light up.

in the early 70s maybe, but by 1991? not really, you definitely still might not be wrong, but a microcontroller makes more sense especially since the F-91W logic is pretty much entirely contained in a single chip

Machine language

microcode

Assembly

Since they've been making digital clock IC's since the 70's, it would seem silly to move to a microcontroller that is going to be more expensive and more work to implement the functionality that is already available in hardware. Also battery life is probably going to be much better for an ASIC compared to a generic microcontroller

Watch sent from heavens to assist terrorists in their daily activities against kuffar and homosexuals

>but a microcontroller makes more sense
it's logic is a bunch of flip-flops on a chip, even in 1991. nothing changed for years.

that's acceptable to me, maybe I'm just taking a more half-assed modern perspective towards the issue where implementing the clock+alarm functionality in dedicated silicon just seems a little more wasteful and harder to debug compared to using an off-the-shelf controller that probably wouldn't make much meaningful impact on battery life.
just wish one of these teardown articles would crack open the fucking epoxy so we can actually see what IC is buried under it

fact : I unironically bought this watch a few months ago because I wanted to have a way to know what time it was during exams because we're not allowed to have smartphones.

didn't know it was a meme watch

>bought one
>didn't know it was a meme
>how cool is that?
Congratulations. You're a faggot.

booooo, assume he's telling the truth, come on man

do israelians really think that translating radicals Islamic scholars make Muslims look bad

I bought it because it was a terrorist watch. I wanted it to match my thinkpad.

Energy consumption of a large CMOS process is mostly dependent on how often you're switching things, an alarm for example is going to be more efficient as a magnitude comparator that's got one side sitting still until you change the time and the other side updating once a minute than it is to move the data in and out of a RAM block into an ALU and back out.

Not him, but I want to know.
I had one when I was like 10 years old and I loved it so much. That was in the mid 90s. I saw one on Amazon like 4 years ago and I bought it. I never wear it, I just keep it tied to my belt when I work on the farm and don't want to get my phone wet and dirty.
How is it a meme watch? I'm curious.

Electron.js

VHDL.

Because it is suspected that terrorists use it as it has been used to make time bombs.
And just because it's a """meme""" doesn't mean it's bad.

It's not suspected. Wire the speaker to a trigger. Done.

I alerted the ATF

Good goy. Enjoy your name being added to a list.

I bought one a few months ago. One of the best choices I've ever made. Retro, sport and classy at the same time. Goes with every outfit, whether you're going for a casual or formal style.

it's not for everyone. my friend noticed that i was wearing an f105w and i told him what it was and why i bought it. ff 1 month he bought one himself in (((gold))). gold doesn't look good on these but he's a huge jew i guess. he wore it for a week or so and then used some mechanical chink watch.

Personally I dont like how it looks on people past age 18.

Nah, they are perfectly capable of doing it themselves.

Semites were a mistake.
t.G-d

I think even Mueller has one.

ye

is he a vet?

I see. I can assure it looks good on me though (it's the only accessorie that I wear and be confident about it for sure). I agree with you on the gold color. Was thinking about buying it in gold, but very few people can pull it off. Silver looks good on me.

Lucky me then, because I'm just 18. I rock this nerdy/retro look quite well, without looking like a hipster. Feel good about it.

Fuck off zoomer hipstertlet

It's a cool watch to be honest. Sadly it doesn't fit my outfit. :'(

Japs and Swiss got into a most accurate quartz crystal war back in the day. The end result was accurate cheap watches.

yep, silver looks nice.

g shock

I've got myself AE 1200 the same way. It just was cheap and looked interesting.

Fuck off cunt.

There are variations of this watch. OP's one is more athletic. Silver/Gold more casual. Not a big deal, I just wanted to not check my phone every 5 mins or so.

there's no way an HTML rendering engine can fit in the computer used in these watches

What did you achieve when you were 25 years old except drink Monster energie drinks and jack off to porn after a 12 hour League of Legend marathon?

Fucking pussy

what kind of tool would I need to replace the band on one of these? and where can I order it? The rubber snapped on mine. I'd like to get one of the Jow Forums approved nato straps

>goes to war
>risks his life for his owner's profit
lool, what a looser. At least go to war for something good, not some game beyond your scope.

wasn't this assclown supposed to be the saviour of the west or some such
