What aspect of Seiko watches draws you in the most?

Hypothetical longevity, venerable autos (all my new Seikos are 7s26 but have a 4r36 coming soon! =), appearance, styling, affordability. Beyond that, potential customization options.

I haven't had all that many in-real-life discussions about watches since getting obsessed with Seiko nearly 2 years ago now, but most of them have seemed to include people's disinterest and distaste in Seiko and an unwavering belief that they are 'cheap' or 'junk'. Part of me thinks people might be mixing/lumping Casio and Seiko together (not that Casio are shabby either-- many people confuse 'affordable' with 'cheap'). Otherwise it's just complete ignorance and lack of knowledge on the product. Seiko pumps out 100,000's of watches per year, no? There are bound to be duds (as with any manufactured product), but not for one second do I believe all these people who hate Seiko have tried one and gotten a bad one in order to form their opinion.

The only true victory in the situation is that we possess the knowledge that they don't; that our timepieces will probably cost less and last longer than theirs will, and we won't have to change any batteries.

As others have mentioned it would be so easy to check all those boxes !!! :-d

Vertical Integration:
I think this is the key strategic advantage which impacts most of the other areas where Seiko are very competitive. Seiko is possibly the Worlds most integrated Watch Co....Yet you don't hear them riding a huge wave of marketing hype about it.Bracelets, batts, lume, crystals, mvt oils, IC's, LCD components etc,etc
I believe Epson even make some of the high tech machines used in some of the production processes.

Quality/Value: (I believe is closely linked to the high level of vertical integration)
Be it at the lower end (eg Alba/Pulsar and lower end Seiko lines), mid end (eg Brightz/Prospex etc), or higher end (GS/Credor/Galante etc). Seiko pieces are almost always highly competitive for quality/$.

Technology:
Seiko has a genuine, consistent and very long history of successful innovation. They seem to have made relatively few mis-steps over the years in the pursuit of such innovation.

Marketing:
Seiko do not seem to go in for quite as much hype marketing as some other companies. (eg endlessly promoting some kind of convoluted professional connection such as military,aviation etc) This particular type of marketing seems to be on the rise and i for one find it less appealing. Many people may say that marketing is a Seiko weak spot,...Perhaps true,..But it just makes me like 'em even more ! :-!

Under The Radar:
Seiko is perhaps somewhat of an under the radar brand in the eyes of many. Abilities often far exceed the attention received, which i find also very appealing.
