Great watch - sturdy, robust, looks great, love the tritium on the watch face. Watch height is a bit too tall to wear with, say, a dress shirt and suit - but otherwise I have been wearing it 24/7 and have no complaints. Looks phenomenal on both leather and nylon NATO straps as well.

Legitimately one the nicest watches I’ve had the pleasure of owning. Top notch fit and finish. It is a great mix of rugged utilitarianism and sophistication. Definitely recommend getting one if you’re looking for a watch that can go out into the field and be left on for a night out too.
