Bronze Aquatimer Charles Darwin
The Bronze Aquatimer is a watch that I was super excited to own. The bezel system is a very cool feature. The different colors of lume are neat to behold. And I really enjoyed the patina that could be easily reversed with a little ketchup rub. I also really like the fly back movement. But the watch had one flaw in design that made the watch a failure for me. The quick release strap system with fixed bars was horrible. It was prone to releasing during wear. I once lost the watch overboard as it bumped the windshield while docking. Thankfully we were in shallow water so I was able to retrieve it, but the idea that a dive watch could easily be unsecured made me completely lose faith in this watch.

The incident with the strap you describe is scary - and this isn't the first time I've heard of accidental detachment with the Aquatimer quick-change system.
I used to own the Charles Darwin Edition myself, and while I never had the strap detach on me, I was often nervous. What I never could figure out is why IWC implemented the quick-change strap on the Aquatimer to begin with, since to my knowledge. they've ...
Sorry
I no longer have the watch, but where the strap attaches at the lugs there is a hook that cli-s to the fixed bar. If the strap is struck near the lugs, it releases. I had it happened to me a few times before it happened on the water.
Did you figure out what failed?
Was anything broken on the strap, or did it just release? I shopped the Darwin, but ended up with the steel Cousteau version. I haven’t experienced a failure, but have read a few accounts of the strap coming off.
