Built for adventure seekers who want a slim profile and legible design, the Flatline Chrono is our premier adventure watch. As a replacement for the Titan III, we wanted to create a smaller and thinner watch, with a similar pilot design. This model will come standard with sapphire crystal. The Flatline Chrono is extremely thin at only 10.6 millimeters in thickness, this is the thinnest we are able to make a watch with a screw-down crown which means that we can still retain 100 meters (330 feet) water resistance. We’ve strived to design the perfect adventure watch. If you like high-grade lume and a classic style then the Flatline Chrono is for you.
