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