Only 50 timepieces are being made.

The Midnight Grey has Old Radium Swiss SuperLuminova lume on the indices for a vintage look with Lumed C3 SuperLuminova subdials. 

Named after the USS Constellation ship, located at the Baltimore Inner Harbor.  The USS Constellation is the last sail-only warship designed and built by the United States Navy in 1853.  As a historic landmark, the USS Constellation is part of the Historic Ships in Baltimore and is the only intact naval vessel from the American Civil War. 

The Constellation Chrono-Diver is a stunning and reliable grab and go timepiece.  It's 200m water resistance, stainless steel case, incredibly accurate meca-quartz movement, and swiss lume is the perfect companion for any adventure.

David D. ★★★★★

The lume on this one is genuinely stunning—the Old Radium glow on the indices gives it such a warm, aged character that pairs beautifully with the brighter subdials. Knowing only 50 pieces exist makes wearing it feel special every time I glance at my wrist.

Victoria Y. ★★★★★

The dual-tone lume setup is the real standout here—those Old Radium indices glow warm and aged while the C3 subdials burn bright and modern. It’s a subtle contrast that makes the dial feel alive in low light, and knowing only 50 exist makes every glance feel a little special.

Lucy E. ★★★★★

The subdial contrast is what sold me—the C3 lume pops against that grey dial in a way photos just don't capture. Number 47 of 50 arrived perfectly packed and the vintage radium tone on the main indices gives it real character.
