The tube and crown are nicely done. Crown screws in smoothly to the base without any hang ups. It sits flush with the case without any contact with the bezel unlike my Silix version. Crown is nicely machined and the B is crisp.
The clasp locks positive without any play in the locking tab. It has a very positive snap upon closure. The engraving is done just as well as everywhere else.
I took the watch into water with out any issues. Tested to 5ATM
