Show me a dial indexed in full-range, 1-12 Arabic numerals and you've got my attention. Cloak the numbers in lume, have 'em framed and set against a contrasting dial and you'd pretty much have me sold on it. Casio's early 2013 Japan release WVA-M630B-1AJF Waveceptor has all these attractions and further ups the ante with Multi Band 6 solar/atomic, multi-function digital display and an affordable price.

Another thing I like are pocket radios. While "window-shopping" watches at Japan Amazon, I came across what I then thought to be a small Seiko alarm clock radio. It was a unique JDM piece that featured a lumed and lighted analog clock with digital AM/FM, 3-way power, emergency siren, LED light and IPX4 water resistance. As it turned out, the mighty KR885N is not too small and it certainly is not pocketable.

Although I received both of these over a week ago, I held off opening 'em up till I had a chance to photograph my first ever double unboxing, this past Sunday. Then it has taken couple more days or so to get a shot at getting this thread up and running. So, hope you enjoy it.

Not one, but two boxes stacked and waiting for days on end to be opened.

Box surgery

Poor packaging with inadequate padding but JDM Casio box is a sign of good things to come

...Out and on top of the box

Exposure to light on case opening, awakens the watch from power-save sleep, setting the hands on a quick clockwise trip around the dial to settle at Tokyo time 13 hours ahead of EDT.

Bigger than imagined. Full-sized with a prominent dial.

Head-on shot for case and dial detail

Sideways to reveal some of the dial's shiny intricacies through the veil of protective lens film

Thick, stitched all-around, leather[ette?] backed, heavy-duty fabric band with riveted holes.

Squared up lug gaps and framed numerals are flattering design touches

Those deep rivets make unbuckling a bit of a chore that requires deliberate folding of the band back against the buckle to free and hold the tang away from the rivets lest it gets caught in one of the next holes up when pulling the buckle off.

Bathed in noon light

Onto the much heavier box #2

Absolutely no padding for the alarm clock radio and the heavy, optional AC adaptor boxes inside.

My total unfamiliarity of Japanese doesn't stop me from guessing that this a comparison chart of run times between external batteries and the internal rechargeable one. Would love it if some of our Japanese-speaking members came to the rescue here as there's nary a word of English anywhere on this product. A JDM item through and through.

Features in pictogram, L to R: Rechargeable internal battery; analog alarm clock; AM/FM; hand-crank recharging dynamo; siren; LED flashlight.

Seiko's tight, protective packaging runs in sharp contrast to Amazon's careless job.

Radio and sundry of plugs, ports and cable. Another cool feature which was left out of the pictograms on the side but appears on front of the box visible here; is the cellphone charging capability.

LED flashlight on the side

Top. Flashlight button on the handle. Snooze bar on body which also activates clock light while pressed.

The dynamic duo in size comparison

Say what?!

One more look at the entire box contents including the Japanese manual

And last but not least, the optional AC adaptor, which goes a long way in completing the package unless you're into hand-cranking.

Here's the google-translated Casio and Seiko write-ups on each respective item:
