... I have the same feeling about RM, ALS, L(aurent) F(errier), VC, H(ublot), Z(enith), P(anerai) and many others. Oh, as for P, all the models are just so similar. Not that it is bad, but just my personal perception.
After all, these derivatives of Seiko are not regular models, but limited edition models (which tend to be sold out quickly) - some of the above does the same, but some others do it A LOT for regular models, too. Watch brands are watch brands. That is what they do to survive, IMHO. And that's fine with me. I know, I, too, find it hard to get excited about those brands' new models.
