Thank you for your continued patronage of the Grand Seiko Boutique Online.
With the expansion of the Grand Seiko ID service, it is now possible to register as a new member via LINE. However, at this time, new member registration via LINE is not available at the Grand Seiko Boutique Online. For new member registration at the Grand Seiko Boutique Online, please register using your email address.
We are currently developing a system that will allow new member registration and login via LINE at the Grand Seiko Boutique Online. We will inform you again as soon as it is ready, so please be patient.
We will continue to strive to provide even better services, and we ask for your continued patronage.
