Could be reliability or voltage related, more likely just availability Japan didn't participate in most sanctions and Asian goods are more readily available in the Middle East.

>Japan didn't participate in most sanctions and Asian goods are more readily available in the Middle East. As opposed to watches made in the US or Europe? Aren't most electronics made in China/Japan anyways?

Yes but the brand and parent company are what affects the distribution not the place of manufacturing.

Timex being an American company is less likely both historically and now to sell in say Iran, Iraq or Syria than a Japanese or even a European company.

Historically as far as electronics, cars and similar things go Asian and European brands are more common in the Middle East than American ones.

Even today where you'll have an electronic optics, laser designator, night vision, a bunch of different radios, and even PDA's if you are in the US, but still no bloody watch.

Can't navigate without one properly, can't know if you are keeping the correct pace when on patrol, can't know when you need to get up to a watch or when you are about to be replaced, can't calculate the distance of enemy fire can't do squat without a watch, but still they don't give you one.

Did you mean an analog quartz watch? A date function there shouldn't have a huge impact in battery life, though if you don't want the date, you may as well conserve. But on a mechanical watch, many common movements have a calendar wheel which is powered by the gear train, it doesn't use a disproportionate amount of energy from the mainspring (compared to moving the hands).

That does seem odd. OTOH probably the cheapest way of procuring a watch is to let you order one from Amazon.

The UK issues these watches

http://www.cwcwatch.com/collections/general-service-watches/...

I only ever saw them when checking stores - Q would never actually let you take it out and use it!

Maybe you were 'issued' them as well, but like ours they're never let out of the stores?

My guess is ubiquity. That is, its no better than most watches technically. But bomb making is also about supply chains and training.

When you make a detonator, you really, really want it to work.

If you show someone "the wires go here and here" on a specific model you don't need to teach them "real" electronics, and theres less uncertainty that the final product will function.

e.g. Arduino is rarely the best mcu for any given application, but it's popular because a) its easily to source and b) there are plenty of "recipes" to follow which don't require much expertise.

I haven't disassembled one before, but perhaps the F-91W features a circuit with an especially easy to break out pin for the beeper, or perhaps it's already exposed in some vital way so as to allow easy access without much prep in the field?

My personal guess as to popularity : volume. Those watches are everywhere.

Yeah, they're also hugely personal and there is tons of interest for a "real" military watch outside of militaries. Most accounts I've read say that people in the US military like G-Shocks and other cheap simple digital watches like this Casio. There are quite a few G-Shock fans around the world, and my personal favorite is the G-Shock G-056 since it's the thinnest G with solar and an atomic RX.

When we were starting basic training with the RAF we were instructed to buy the F-91W specifically and to leave fancy watches at home. It made exercises easier to instruct when everyone's watch worked the same way, plus I suppose it reduced one of the temptations of pilfering in the barracks.

Of course there was always one joker who bought the bright-pink edition ;)

This could be a hold over from habits established before cell phones became common. Back before, say, the '90s, most people in the US (and I assume in most other first world countries) from their teens onward had a watch.

Perhaps militaries assumed that everyone coming in would already have a watch.

Furthermore, watches were often of great sentimental value, and many people would have viewed the military telling them what watch to wear as being as absurd as, say, issuing a standard military wedding ring to married soldiers to replace their civilian wedding ring.

As long as a soldier's watch was accurate and reliable enough for military needs, they probably saw no reason to not let the soldier use his own watch.
