SSC813 vs SSC911
Two solar Speedtimer chronographs: the 39 mm SSC813 and the larger 41.4 mm SSC911.
The differences that matter
- Size: the SSC911 is 2.4 mm wider (41.4 vs 39 mm), and 45.9 vs 45.5 mm lug to lug.
- Movement: both use the V192.
- Availability: neither is sold new by Seiko US any more, so both are mostly bought pre-owned.
Side by side, to scale
- SSC813 39 mm · 45.5 mm lug to lug · 20 mm strap
- SSC911 41.4 mm · 45.9 mm lug to lug · 21 mm strap

Rough rule of thumb from lug-to-lug length, not a promise. Wrist shape matters; try one on if you can.
