I managed to check out the new Seiko Criteria automatic and found out that it has integrated bracelet just like the previous model. You can remove the bracelet but not the ‘end pieces’ because they are part of the watch case. It is not a big watch, probably the same size as the previous model.
I feel that for the Criteria auto, Seiko needs to design something radically different from the Seiko 5 Sports. This series look so much like the Seiko 5 Sports that someone is already calling them "sport watches" (link below) without mentioning the "Criteria" name. It is a sports watch no doubt but there must be something significant enough to differentiate Criteria from Seiko 5. Right now they have the same movement, similar size, same quality, same WR rating, same display back feature and of course, similar design.
