The Bronze Spectrum: A Stainless Steel Transformation

A Finish Born From Fire, Light, and Pure Stainless Steel

Chromatic Bronze is not a coating.

It is not applied.

It is revealed.

This finish emerges only when 303 stainless steel meets oxygen at elevated temperatures. An elemental interaction that unlocks the bronze-gold spectrum hidden within the alloy itself. The result is a surface that behaves like liquid light: shifting between gold, violet, and deep blue with every movement of the hand.

It is a finish defined not by uniformity, but by character. Each putter developing its own signature tones, textures, and halos of color. No two heads oxidize in the same way, making every Chromatic Bronze build inherently singular.

The Metallurgy Behind the Glow

303 stainless machines like butter and gives you that softer, carbon-steel-inspired feedback players love. But those elevated sulfur and phosphorus levels the same thing that makes it cut so clean also make it extremely unpredictable once you heat it up. That’s why true oxide finishes on 303 are almost unheard of.

As the alloy warms, the metal transitions through a spectrum:

• Straw gold

• Deep honey bronze

• Violet edge tones

• Blue-green prismatic highlights

This layered chromatic effect cannot be replicated with PVD, Cerakote, or electroplating. It is a true metal conversion. Stainless steel expressing its own internal color structure.

The surface refracts light with a pearlescent, opalescent quality, giving the finish a sense of depth and movement that appears almost alive.

A Finish Reserved for Stainless, Not Coatings

Because chromatic bronze is a natural oxide, it is best left unsealed.

A synthetic topcoat would mute the tonal shifts that define the finish.

Care is simple: a microfiber cloth, a dry head, and clean metal. When the surface remains untouched by oils or moisture, the color becomes clearer, brighter, and more dimensional over time.

This is a finish that matures. Never fading, only deepening.

The 7.2: A Canvas Built for Light

The Phantom 7.2 provides a rare geometric architecture for this finish. This specific model arrived factory-built with a single topline–an increasingly uncommon detail–allowing a full, uninterrupted chromatic treatment across the head.

Every detail was considered and refined:

• Even, hand-torched chromatic bronze across the stainless head

• Matching torched stainless weights for tonal cohesion

• Gloss black alignment line + flange lines to heighten contrast

• Transparent candy black cavity dots, face stamping and sole weights revealing golden undertones

• Tour-Level neck welding, adding a touch of prestige

The combination of gloss black against shifting bronze creates a visual tension found only in bespoke luxury objects. Modern, timeless, and mechanically pure.

A True Metal Finish, Not Reproduction

Chromatic Bronze cannot be reproduced after welding deletes or stamping removal. Weld alloys oxidize differently from 303 stainless, breaking the continuity of the color shift. Only a head that retains its original metal composition can achieve a seamless chromatic finish.

This makes the 7.2 shown here unusually rare: a factory topline stainless head, untouched and perfect for a full chromatic transformation.

The Final Expression

The completed putter is:

• A true oxide finish, created from the metal itself

• A one-of-one chromatic reaction, unique to its alloy

• A luxury build with prismatic depth

• Architecturally suited to the Phantom 7.2 silhouette

• Enhanced with black candy details that invite light inward

• Welded neck, only seen on Tour-Engineer putters

• Alive with color, dimension, and shifting light

This is more than a finish.

It is metal in its highest form. Refined by heat, revealed through oxygen, and captured at the exact moment where art and engineering meet.

A putter like this is not simply played.

It is experienced.
