Here’s a Seiko Brightz SDGM001 that I picked up recently. This is probably the first Brightz model that comes with a 6R15 movement. In the past, automatic Brightz (non-chronograph) models came with the 8L and 4S movements. Of course, this one is offered at a lower price point.
The SDGM001 features the Seiko Comfotex technology which include special treatment to the case and crystal of the watch.
