Some instruments reach the workshop but never reach the world. ENDUR is one of them.
We developed ENDUR as a 42MM automatic chronograph, then chose not to move forward with production. Only two physical prototypes were made: one in raw Grade 5 titanium, and this one in black DLC-coated Grade 5 titanium. This is the only DLC ENDUR ever made.
Not a numbered limited edition. Not a reissue. The actual prototype from a design path we didn't take.
Built to be an instrument
Behind the restrained black dial is the Swiss ETA 7750 automatic chronograph movement. Three registers, a day-date display, broad high-contrast hands, and an instrument-inspired case give ENDUR a distinctly purposeful character. The black DLC treatment takes that design further — less reflection, more focus.
A piece of RDX history
The caseback is engraved ENDUR / PROTOTYPE, along with its original material and movement specifications. There was no production series after these two examples. For the collector who values the work behind the finished instruments, this is a chance to own one of the decisions that shaped Redux.
