As promised, here's a lineup of my new Athaya 702, and the stock crown.
First up is the Athaya, the coronet is well defined, and finishing is top notch. Little-to-no tooling marks on the crown, even on the knurled portion. Also notable would be the o-ring at the end of the threads that feed into the case. This helps tremendously with water resistance, and Athaya has this on every tube sold.
Here's the stock crown, not much going on here.. Soft coronet imprint, from a 703 no less, and also inaccurate for a 703 (and for this watch). The knurling is very rounded and has more teeth than any gen crown. Tooling marks are abundant as well. There isn't an o-ring present between the case and tube, so WR is compromised.
Side by side these are night and day. The stock crown's knurling is way too long, and the crown itself sticks out from the side of the case.
Now this one is just for fun, here I've got the Athaya 702 on the left, and a brand new TC 703 on the right. After close examination of both I've found the Athaya to have superior finishing. Here you can see that the finishing of the knurling is smoother, while the TC has more tooling marks left behind. While I'm happy with both, the result surprised me, although it's better than the slipping Noob V2 114060 crown it's replacing!
