Grand Seiko is celebrating the 20th Anniversary of Spring Drive in style, with a new Grand Seiko Sport design that features a faceted, highly polished case that’s a radical departure from Grand Seiko’s past design language. The new cases, whose angular case, sharp lugs, and dial pattern are all said to be inspired by the claws and mane of the Grand Seiko mascot, have a visual and tactile presence that’s probably going to be pretty challenging for at least some of Grand Seiko’s very engaged fans to accept. Whether or not the new design finds rapid acceptance, or instead will take a little getting used to, remains to be seen, but in terms of quality of execution, fit, and finish, they’re very much what we’ve come to expect from Grand Seiko even if the case isn’t.
