J.N. Shapiro Radiant brings tantalum and meteorite to the Infinity Series

J.N. Shapiro has moved quickly from dial specialist to one of the most compelling names in modern American independent watchmaking.

The new Infinity Series Radiant shows why the California workshop has become so interesting to follow, combining an unusual case metal, aerospace cues and a slim hand-wound chronograph calibre in a watch that feels deliberately outside the usual Swiss-scripted playbook.

It’s also a timely release for the brand, arriving as J.N. Shapiro continues its expansion in Torrance, a city surrounded by Southern California’s aerospace culture.

At a glance

Tantalum gives the Radiant its weight and colour

The Radiant takes its name seriously, not through shine alone but through a material story tied to light, radiation and engineering.

Its 38mm case is made from brushed tantalum, a dense, corrosion-resistant metal with a blue-grey tone that gives the watch a colder and more technical personality than steel or titanium.

For a chronograph, the proportions are notably restrained.

The case measures 9.6mm thick and 43.9mm lug-to-lug, figures that should make the watch feel closer to a dress-leaning independent piece than an oversized sports chronograph.

Water resistance is rated to 50 metres, with sapphire crystals fitted front and back.

Two dials, one aerospace idea

J.N. Shapiro is still best understood through its dials, and the Radiant gives the workshop two very different ways to express the same concept.

The more dramatic version uses genuine Gibeon meteorite at the centre of the dial, paired with a meteorite 30-minute chronograph counter finished with guilloché.

A heat-blued zirconium chapter ring frames the meteorite, with engraving applied after the heat-treatment process.

Matching heat-blued hands keep the display coherent without softening the watch’s technical edge.

The second execution leans further into Shapiro’s signature craft, replacing the meteorite surfaces with a fully guilloché heat-blued zirconium dial and matching sub-counter.

Polished steel hands are used on this version, creating a cleaner contrast against the blue tones produced through heat treatment.

A slim monopusher with serious lineage

Inside the Radiant is the La Joux-Perret 5000-4, a hand-wound monopusher chronograph calibre with a column wheel and horizontal clutch.

The movement’s compact architecture is central to the appeal here, allowing the watch to stay under 10mm thick while still offering a mechanical chronograph display.

Its background traces through an important chapter of independent chronograph development in the 1990s, connected with work by François-Paul Journe and Denis Flageollet during their time at THA, before later evolution through Jaquet SA and La Joux-Perret.

In the Radiant, the calibre offers a 30-minute chronograph counter, 23 jewels, a 21,600 vibrations-per-hour frequency and a 38-hour power reserve.

It’s not a new movement, but it remains an appealing choice for a watch like this because it’s compact, manually wound and comparatively uncommon in contemporary production.

Production, pricing and straps

The Infinity Series Radiant will begin with a first production run of 75 pieces.

Deliveries are expected to start in the second quarter of 2026, with orders requiring a 50 percent deposit.

Each watch is offered on an alligator leather strap with a pin buckle and 20mm lug width.

An optional AHA tantalum bracelet is also offered separately for USD 12,950, giving collectors the chance to make the most of the case metal’s distinctive tone and feel.

Details & Specifications

The Radiant is the kind of watch that will speak to collectors who want American independent watchmaking with a genuinely technical streak, rather than a familiar design simply dressed in unusual materials.

Between the tantalum case, meteorite option and slim monopusher movement, it makes a clear argument that J.N. Shapiro’s Infinity Series is becoming more than a secondary line.
