The ​​Fortitude combines titanium with an anti-magnetic case to help prevent the effect of electro-magnetic fields caused by smartphones, computers and various devices that could mess with your watch’s accuracy. This watch is 5 times more resistant to magnetic fields than the ISO 764 magnetic-resistant watches standard for wristwatches, built to keep on ticking in all flight conditions even at 40,000 feet.

It's extremely ​​resistant to magnetic fields, preventing the effects of time lag.


The Fortitude was engineered to help you take your landings, not distract you from them.

Designed to make a statement, yet be rugged and functional, the Fortitude boasts large legible hands and boldly printed indexes filled with ultra-bright Super-LumiNova for quick time reading. The sand-textured sandwich dial adds depth and character paired with the polished titanium casing.

The GRADE A BGW9 Super-luminova is an upgrade from our previous models, making visibility even more exceptional at night. 



Inspired by the “Remove Before Flight” tags that need to be removed as part of the procedure for takeoff, HexCrown is the custom crown designed with a red line to ensure that the crown is fully screwed down for maximum water resistance. 

With one look, you can tell exactly if your crown is fully screwed on. For peace of mind all day long.

made for you to soar to new heights every day.

These are the watches of the air. The Fortitude was made to fly. To push limits. To break records. And to make you feel like anything is possible.

The Fortitude is a titanium pilot watch with 41mm anti-magnetic case. NH35A automatic movement underneath a sand-textured sandwich dial and Sapphire Crystal with inner-side Super-AR. 48mm lug to lug with quick-release titanium bracelet. 100m water resistance featuring a unique HexCrown system.

Our watches are designed for pilots, by pilots. So when it’s time to suit up for takeoff, you have the right look.

Superb on the Wrist

Very prompt delivery and a real experience unboxing. Easy to reduce bracelet with tools provided. Good size and weight when wearing. Very pleased with the purchase of my first titanium watch.

Love the look and feel but a bit dissapointed

At first glance I was in love with the overall look and detail. It also feels much lighter and comfortable than a traditional stainless steel construction which is to be expected. This is the second full titanium watch I've purchased and love the reduced weight but durable and the absense of an overly polished glitzy chrome/stainless steel piece. I do have 3 issues that make it less than what I was expecting. 1. The date and window is way too tiny especially under poor lighting conditions or light source glare. 2. The lume doesn't seem to sustain for very long. According to what I could find regarding the advertised type it should last 3 to 5 hours after light exposure and I've been barely able to see any glow left after an hour. 3. The dial size seems under stated at ~35mm even on my wrist which is smaller than most and a case size of 41mm. It was difficult to tell how it was going to look until actually putting it on. I've worn it every day since receiving it hoping I would grow to like it more. I'm still waiting however considering the price and lack of full titanium models available. One last thing or feature request of a future model is an added slide rule. :) I really don't intend to come across too critical as I do really like what RZE is attempting to do and appreciate it!
