Grand Seiko SBGR255

The SBGR255 and SBGR257 may be among Grand Seiko's most affordable automatics, but they have all the quality and sophistication of their more expensive counterparts.  For one, they share the same 9S65 in house automatic movement that most Grand Seiko mechanicals do.  The 9S65 is an amazing movement with accuracy superior to Swiss chronometers.  It also has a 72 hour power reserve, 80% longer than the industry average of 40 hours.  It features advanced watchmaking technology to make that possible, like an in house SPRON alloy for the mainspring and hairspring and MEMS technology for near-molecular level precision manufacturing. Like all Grand Seikos, it's hand assembled and polished by certified master watchmakers from start to finish before it goes through a 17 day testing period.  The 39.4mm size offers a more sporty alternative to other Grand Seikos, as well as its aggressive crown guards and the fully brushed bracelet.   The SBGR255 is the latest version of the Grand Seiko SBGR055.
