SEIKO 5 – the meaning of the “5” A great marketer had the idea in the 70ies: to be a SEIKO 5, the watch has to have the following 5 (five) attributes (thus the name SEIKO 5): 1. Automatic, 2. Water resistant, 3. Shock resistant, 4. Date, 5. Day. Please note that some SEIKO 5’s are in fact SEIKO 4’s, if the “Day” function is omitted, then the Caliber 7S25 is used. The only difference to the normally found 7S26 is the omission of the day wheel. Also re-issues of SEIKO 5 Sports often use the 7S36 caliber. Again the 7S36 is similar to the most popular 7S26, yet it features 23 Jewels as opposed to the 21 Jewels in the 7S26. Please note that all these movements beat at a rate of 21’600 bph (beats per hour) or 6 bps (beats per second). As a comparison, an ETA 2824-2 beats at 28’800 bph or 8 bps. A Miyota 82xx beats at 21’600 bph. Why do I mention these three movements? Because they are found in probably 80% of all inexpensive automatic wrist watches. A market share that is huge, yet challenged these days (2006) by an increasing share of inexpensive China Made automatic movements An automatic watch (also called a self-winding watch) is a mechanical watch, typically with a balance wheel escapement, whose mainspring is wound by the motion of the wearer’s arm, instead of having to be wound manually every day. Whereas a quartz watch is powered by electricity, a mechanical watch is powered by a mainspring which must be rewound for the watch to keep time.

Received Korean version, not Japanese version as advertised in listing Product in the listing is described as the Japanese-manufactured version of this watch, not the Korean version. Says “Made in Japan”, and SNZG15J1 right there in the listing title. What I received instead was the SNZG15K1 (K for Korea), AND it wasn’t even in the manufacturer packaging. (It was in a Ziploc bag, of all things, which makes me suspect it might actually be refurbished. Either way, it’s definitely not new.) Bag was labeled as the “J” model, but the tag on the watch had the “K”. If you’re buying from this listing specifically for the J serial number, carefully inspect your watch when you get it.

Handsome, reliable, accurate – great watch! One of my all-time favorite Amazon purchases! Exactly what I was looking for: A reliable, tough field watch, easy to read the time quickly, water resistant to 100M, and automatic. Very comfortable, and the band, though simple, is comfortable and fits the looks of the watch perfectly. I’ve worn it steadily for a couple months now and it has not skipped a beat. This is a classic watch, one to start a watch collection with; check the reviews here on Amazon and take a look at YouTube. I wear this more than any of my others, and I’ve got a multi-watch collection of higher-end timepieces. If you can’t afford a Hamilton, this is your watch. And if you can afford a Hamilton, this is still your watch. Accurate and rugged, this Seiko is a great, handsome everyday timepiece that demands no special care other than that you wear it regularly to keep it wound. And you *will* wear it regularly! A wonderful watch!

You know why you want this watch so just get it. I honestly didn’t even put it on with the original strap. I replaced it with a Nato strap the second I took it out of the box and it looks/feels good. I don’t think I would have enjoyed what it came with but nobody orders this watch for the strap. You order this watch from Japan because of the movement and overall qualityThe watch does say Made in Japan on the front and back, and it came with a Japanese warranty card. I don’t doubt its legitimacy, but I am surprised to see that my days are in English and Arabic. Everything is easy to read. The luminescence is good and the glow strip above the 12 is a triangle which makes it much easier to get the time in the dark.Downsides: The mechanism is non-hacking (seconds hand does not stop when you are setting the time) so accuracy is to the minute at best. Additionally, the warranty is only valid in Japan. And that aforementioned strap is just hideous. Seiko can do better. It comes in such a nice presentation case. I’d rather it…
