Model: Seiko SUS Mechanical GMT SCFF009 (4S12-0010, Blue Dial)
Overview: The SCFF009 is a rare late-1990s mechanical GMT from Seiko’s SUS line, distinguished by its deep blue sunburst dial and unconventional tool-watch design. Powered by Seiko’s high-beat 4S12 automatic movement, it represents an interesting period when Seiko was producing a small but technically ambitious range of mechanical watches for the Japanese market.
History: The SCFF009 was produced alongside the black SCFF005 and red SCFF007 as part of Seiko’s mechanical SUS GMT family. The 4S12-powered models appeared in the late 1990s, during a period when mechanical watches occupied a relatively small part of Seiko’s catalogue. The 4S family itself descended from Seiko’s earlier 52-series architecture and was used across several enthusiast-favorite watches of the era.
