My impression of that extraordinarily long development phase is that spring drive was a back burner project for a long time, almost got cancelled once or twice
It spanned the quartz revolution then the solar amd kinetic stuff then the mechanical revival
Seems like a brainchild/pet project thing one or several seiko guys kept alive for a long time and devoted resources to it on a sporadic basis
Rather than a heads down Manhattan Project for 28 years.
Yes. It's novel rather than pushing technological or material boundaries, or exceedingly complex. There would have been a fair bit of R&D to get it right, adding to the cost of early units. Seiko's done that hard work and the patent's expired so it wouldn't be hard or costly for somebody else to make them now.
I'd venture it's not that easy or we would already be seeing them.
That’s one explanation and sort of Seikos line, these are high precision mechanisms put together by highly trained techs etc
Spring Drive may be a solution in search of a problem. It doesn’t really offer anything other movements don’t
The smooth second hand is kinda cool and entertain when you focus on it but otherwise provides no benefit and a high beat movement is pretty close
The accuracy isn’t better than quartz
So perhaps one reason nobody else is making these is because nobody is asking them to do so
Dint get me wting though I think spring drive is cool amd I’ve owned some
