Precision in Every Hour.
24-Hour Navigation, Reimagined.
It started with an inheritance — a non-functional WWII-era G.C.T. pocket watch that once guided pilots and officers through the fog of wartime navigation. Rather than let it sit behind glass, I spent two years reverse-engineering its soul.
The 2442 G.C.T. is not a reissue. It is a complete re-engineering. Every dimension, every tolerance, every material choice was interrogated against one question: does this serve the instrument?
MARTINNY is both my name and my wife Winny's — she documented this entire journey, from the first sketches to the prototypes you see today.
I didn't start with a brand. I started with a pocket watch that stopped running. Learning to repair it taught me that clarity of purpose is what separates a tool from a trinket — so I built the watch I couldn't find anywhere else.
From a grandfather's pocket watch to a modern 24-hour instrument — Martin shares the engineering journey behind the 2442 G.C.T.
The no-date decision makes complete sense for a true tool watch. Symmetry and legibility over complication — exactly right.
11.8mm on a 24-hour automatic is genuinely impressive. Most brands can't get close to that without compromising the movement.
Love that the metal tin packaging follows the same philosophy as the watch itself. Utility over aesthetics. This is how it's done.
We don't just build watches; we re-engineer history for the modern wrist.
What started as an obsession with a broken WWII pocket watch became a two-year engineering journey. Every decision — from the Miyota 9075 to the 11.8mm case profile — was made with one question in mind: does this serve the instrument?
MARTINNY is not a fashion brand. It's a precision workshop with a name on the dial.
The 2442 G.C.T. KS Edition is sold out. A second instrument is in development — built on the same engineering philosophy. Be the first to know.
