The seller claimed these were military grade cases from the Op supply. I have liberally dosed more than a pinch of salt on that one, but the movements are original incabloc 6497's, the sandwich dials are soooo classy and faultless. My only gripe (non overly fussed) is the weak lume on the numerals and I have never tested the water resistance.
The cam on the crown lock is a great piece of engineering - would love to see this type of feature on a CW - 9 o'clock position for a leftie.... I couldn't decide on SS or black shiny PVD (almost ceramic in look) so went for both. whilst both are currently on brown straps (one nubuck camel / white stitch and the other croc grain), changing these gives them a whole new character. My "stock" includes various leather colours and textures as well as an original OP rubber with deployment....
