That is certainly and certifiably true :)

Although I'm very fond of Springdrive (and Seiko in general), it's just an example that I thought would be more recognisable than, say PP's use of ceramic components. I wouldn't want to claim any of these advancements as more significant innovations than Co-Ax escapements in what is increasingly an art-for-the-sake-of-art (or tech-because-we-can) endeavour anyway.

It's best just to marvel and to start thinking of how to explain the expense to the significant other.
