Was just about to post the exact same thing re: the T10. With you guys, seems like too much competition though haha! I've also thought about doing a unique case/dial request for the Optimum.
Now I feel the other way around. I think the T30 has more soul even if I love the T10. A timeless beauty that is difficult to pinpoint. The silver case is a bit impractical as it see to oxidize a lot. Still it seems like a wearable watch.
