The Cipher Diver: Built for the depths. designed to hide a secret.
Inspired by the covert ingenuity that helped secure America’s independence, the Cipher Diver is a mechanical dive watch with a secret.
At a glance it’s everything a proper dive watch should be—300 meters of water resistance, exceptional execution, BGW9 Super-LumiNova, and a remarkably thin 11mm profile.
But hidden beneath the sapphire bezel lies something more. A UV-reactive cipher (patent pending), completely invisible in daily wear and revealed only when illuminated. Using time itself as the reference, messages can be encoded and decoded directly on the watch.
Inspired by Covert Ingenuity
The previous release sold out in hours. This return refines the concept—now featuring a bi-directional bezel for faster cipher use, and five new colorways.
Each Cipher Diver includes a UV decoding torch and the first encoded message (on the caseback). New ciphers will be released weekly throughout our nation’s 250th year and through 2027.
Built to be worn daily.
Designed to be discovered over time.
Refinements & Five New Colorways
This new generation brings a series of thoughtful refinements.
The traditional unidirectional bezel has been replaced with a 120-click bidirectional bezel—faster, more intuitive, and purpose-built for using the cipher in real time. Subtle updates to the brushing and polishing elevate both grip and visual depth, adding a quiet sense of precision throughout.
And for the first time, it arrives in five distinct colorways—each one giving the cipher a different personality.
- Black Bezel, Green Dial (AKA “Reverse Starbuck”)
- Blue Bezel, Green Dial, Yellow Second Hand
- Blue Bezel & Dial, Light Blue Minute Track & Yellow Second Hand
- Black Bezel & Dial, Purple Minute Track & Purple Second Hand
- Black Bezel & Dial, Grey Minute Track & Red Second Hand
Illumination
The Cipher Diver features high-grade BGW9 Super-LumiNova on the hands, indices, and bezel pip for excellent low-light legibility. Hidden beneath the sapphire bezel are UV-reactive cipher markings, invisible during normal wear and revealed only when intentionally illuminated with UV light.
