STS will do a cap replace at a reasonable charge. Mine needed I think 2 in 5 years. Just like Seiko kinetics, they fail if not worn regularly, they don’t suit rotating in a big collection. The red second hand on that one has faded by the way. These are a nice quirky piece but the compromises and dubious benefits over quartz movements meant they never really caught on.
Some interesting info here, esp about the capacitor replacement Panasonic rechargable cell (ie not a capacitor).
