The Details

A masterful convergence of 1940s chronograph heritage and cutting-edge metallurgy, the Omega Speedmaster Chronoscope in Bronze Gold stands as a uniquely sophisticated addition to any discerning portfolio. Crafted from Omega’s exclusive 9K Bronze Gold alloy—enriched with 37.5% gold, palladium, and silver—this 43mm timepiece offers a warm, pink-hued aesthetic that develops a subtle, natural patina over time without the aggressive oxidation of standard bronze.

At the heart of the watch lies a captivating oxidized bronze dial featuring a bespoke dark patina, contrasting beautifully with silvery opaline sub-dials. The dial’s intricate "snail" design echoes vintage horology, packing three distinct timing scales—a tachymeter for speed, a pulsometer for heart rate, and a telemeter for distance—into an elegant, highly legible format. Solid Bronze Gold leaf-shaped hands and Arabic numerals coated in vintage-toned Super-LumiNova complete the striking, dark-and-gold visual aesthetic. Visible through the sapphire crystal caseback is the manual-winding Omega Co-Axial Master Chronometer Calibre 9908. A true modern marvel, this movement features a unique finish with Geneva waves in arabesque radiating outward from the balance wheel rather than the center, offering exceptional magnetic resistance and certified precision.

Core Highlights

• Proprietary Bronze Gold Alloy: Formulated with 37.5% gold (9K), palladium, and silver, this exclusive alloy delivers a warm pink-bronze hue with high corrosion resistance, developing a slow, soft patina over time without oxidation or verdigris.
• 1940s-Inspired Snail Dial: Features three historical measuring scales—a Tachymeter (speed), Pulsometer (heart rate), and Telemeter (distance based on sound)—printed in a concentric "snail" pattern across an oxidized dark brown dial.
• Calibre 9908 Movement: Powered by a manual-wind, METAS-certified Master Chronometer movement equipped with twin barrels mounted in series and resistance to magnetic fields exceeding 15,000 gauss.
• Refined Aesthetics: Styled with a polished brown ceramic bezel ring featuring vintage enamel markings, leaf-shaped hands, applied Arabic numerals, and silver sub-dials.

Dial Architecture

The dark brown dial showcases an oxidized finish with opaline luster. Beneath the applied 18K Bronze Gold PVD-coated Arabic numerals lies a delicate spiral track pattern. At its center, three concentric timing tracks pay homage to 1940s chronograph wristwatches:

1. Tachymeter: Measures speed over a known distance.
2. Pulsometer: Measures human heart rate over 30 pulsations.
3. Telemeter: Calculates distance based on the speed of sound (e.g., measuring distance to lightning).

Dual silvery sub-dials at 3 and 9 o'clock provide symmetry, with the 3 o'clock register housing both the 60-minute and 12-hour chronograph totalizers for intuitive elapsed-time reading.
