First Look at the J.N. Shapiro Radiant Monopusher Chronograph
A First Complication, and a Design Language Codified
The headline on the new Infinity Series Radiant writes itself. It's the first complicated watch Josh Shapiro has put into series production — a monopusher chronograph from a maker who built his reputation on time-only dials. For J.N. Shapiro, that's a milestone worth marking.
But the complication isn't really the story. The story is what the Radiant tells you about where Josh Shapiro's work is going.
From Influence to Identity
Look back at Shapiro's early watches and the references are easy to name. There's Breguet in the guilloché and handset, George Daniels in the hand-finishing philosophy, Daniel Roth in the dial layout. That's no knock; every serious watchmaker begins in conversation with the legends. What's different about the Radiant is that the conversation has resolved into a statement.
J.N. Shapiro Infinity Series P.01 for Collective (2020)The elements Shapiro has been working with across the Infinity Series — tantalum, zirconium, meteorite, heat-treating, and of course engine turning — stop reading here as individual flourishes. On the Radiant they cohere into a single, proprietary vocabulary. This is the watch where the design codes gel. It ties the body of work together, it pushes classical watchmaking somewhere new rather than simply quoting it, and to put it plainly, it looks killer on the wrist.
A Vocabulary Borrowed from the Sky
The name points to the idea. "Radiant" carries two meanings, light and radiation, and both are wired into the watch.
Shapiro's workshop sits in Torrance, California, in the middle of one of the densest aerospace manufacturing corridors in the world — SpaceX, Boeing, Northrop, and JPL are all neighbors. Tantalum and zirconium aren't chosen here for novelty; they're materials the aerospace industry actually relies on, prized for radiation absorption and structural stability. Add meteorite — material that is, literally, from space — and the Radiant becomes a watch that wears its Southern California roots openly. The space-age metals aren't a marketing veneer over a conventional watch. They're the watch.
The Meteorite, and a Collective Connection
Collectors who've followed Shapiro for a while will recognize the meteorite thread, because part of it runs through us. The sold-out bespoke series J.N. Shapiro produced for Collective Horology back in 2020 is, by Josh's own account, where the renewed appetite for meteorite began. The requests never really stopped, and the Radiant is in part an answer to them.
The meteorite dial uses Gibeon, valued for its tight crystalline structure and the unmistakable Widmanstätten pattern that no two slices share. It's genuinely scarce material — Gibeon is no longer exported from Namibia, which means the supply is finite and getting harder to source. Shapiro works through collectors and auctions to find it. When you see a Gibeon dial, you're looking at something that can't simply be reordered.

The Radiant comes in two configurations, each making a different argument for the same material palette.
The first centers on an etched Gibeon meteorite dial, paired with a guilloché meteorite 30-minute counter, a heat-blued zirconium chapter ring, and flame-blued hands. The second goes all-in on zirconium: a basketweave-guilloché heat-blued zirconium dial with a matching subdial and black-polished steel hands.
What ties them together is a process that borders on punishing. On both versions, the numerals and indices are engraved after heat treatment. That ordering matters. The deep blue of the zirconium comes purely from heat — a naturally formed oxide layer, no paint and no plating — and engraving into an already-treated, already-colored surface leaves no room to correct a mistake. You have to land the color, then land the engraving, the first time. It's the kind of constraint most makers design around. Shapiro designs into it.
The Movement
Powering all of this is the La Joux-Perret 5000-4, a monopusher chronograph caliber with an unusually good origin story: it was originally developed by F.P. Journe for Cartier, and is now produced by La Joux-Perret. Only a handful of brands use it, which suits a watch made in small numbers. It lets Shapiro build a properly classical monopusher — single-pusher control, 30-minute counter, manual winding — in a slim, elegant format rather than the bulky chronograph cases the complication often invites. At 4.2mm thick, with a 38-hour reserve and 23 jewels, it's the right engine for a chronograph that wants to wear like an everyday watch.
A Maker Hitting His Stride
The Radiant lands at a moment of real momentum for J.N. Shapiro. The brand now works out of a 7,000-square-foot Torrance workshop, with a team that's doubled over the past year. The high-end line — movements made entirely in-house — already carries a multi-year wait list, the legacy of being the maker behind the Resurgence, the first modern mechanical wristwatch truly produced in the United States. The Infinity Series exists to bring that craft to more collectors without diluting it, and Shapiro has signaled the Radiant could become a permanent fixture of the line.
The watch itself stays compact and wearable in the metal: a 38mm tantalum case, 9.6mm thick, 43.9mm lug-to-lug, 50m water resistance, delivered on alligator with an optional AHA tantalum bracelet. The first run is limited to 75 pieces.
Final Thoughts & Availability
Plenty of independents can assemble an interesting spec sheet. The best arrive at a design language that's unmistakably their own. The Radiant is Shapiro's clearest statement to date — proof that the materials, the finishing, and the philosophy have fused into something you'd recognize across a room. It's a first complication, yes. More than that, it's a maker telling you exactly who he is.
