It’s the Maratac DC-50 I love that watch. Inner rotating bezel, stainless steel, screw down crown, 50 ATM water resistance, insane lume. Definitely a banger of a watch. Here’s links to the titanium & DLC one they did recently. They’re all all sold out but you can get in the email list in case it drops again. I don’t see the one I have on the site anymore, but the dlc one is stainless steel
