This coming fall (October/November time frame) two new HI-BEAT Grand Seikos will be launched. I got the opportunity to handle these at BaselWorld. However not sharing the pictures until later. Now other pictures have leaked and it is OK to show these.
The two watches are SBGJ017 (champagne dial) and SBGJ019 (black/charcoal dial).
They are fitted in the very classic case (see for example the SBGW001, SBGR061 and SBGM021). They look quite similar to the, since a few years, available SBGE025 and SBGE027, see picture below.
One big difference between the older models and the new ones is the movement.
While the SBGE-versions contain the 9R66 Spring Drive movement the new ones have the HI-BEAT (36kBph) mechanical movement 9S86.
Notice also the nice red-tipped GMT hand and the red GMT text on the SBGJ019.
Both the SBGJ019 and 017 have the perfect diameter of 39.5mm. The display-back is screwed with six screws and the water resistance is 3BAR.
