Seiko 6S Chronograph Automatic
- Column wheel chronograph architecture
- Precursor to modern Seiko 8R chronographs
- Significant milestone in Seiko’s mechanical chronograph revival
Following the discontinuation of the Seiko Speedtimer in the 1970s, Seiko ceased production of mechanical chronographs for over two decades. The introduction of the 6S caliber marked a major return to form, laying the foundation for later movements such as the 8R series and Grand Seiko 9SC5.
Dimensions:
39mm diameter (tonneau profile)
20mm lug width
13mm thickness
Design Details:
- Tonneau-shaped case with strong wrist presence
- Six blued steel hands for chronograph and timekeeping functions
- Applied indices with lume uncommon for this style of Japanese chronograph
- Balanced dial layout with a mix of sport and dress elements
Closing Note:
With its historically important 6S chronograph movement, bold tonneau case, and premium retail positioning, the GCBK993 stands as an underappreciated piece within Credor’s lineup. Compared to modern Seiko chronographs using 8R-based movements, it remains a compelling and relatively undervalued option for collectors seeking both history and design.
