Seems to be, yes. It's not taken any knocks as yet but I think it would shrug them off. I've had the caseback off, and the movement was secured in place very firmly indeed. It's styled after the Panerai submersible, which is a watch I am considering as a future purchase. However since that watch costs over £3.5k on the secondhand market I thought this watch was a good way of finding out if I like the style of it before buy the Panerai.
