説明

訳文を見る

In an era when precision lathes had yet to be fully established, master craftsmen carved solid blocks of stainless steel entirely by hand—hollowing, shaping, and giving birth to form itself.
From this process emerged the unmistakable mass and presence of the TV-shaped case, its raw weight unapologetically exposed.

From that sculptural body flows the original integrated bracelet in a seamless continuation—each surface radiating the sharp brilliance unique to stainless steel.
At its heart, the applied “125” on the black dial stands not merely as an emblem, but as a vessel—breathing life into one of the most intense chapters in the history of the Speedmaster.

To ensure that all 2,000 pieces would pass chronometer certification, the Caliber 1040 was meticulously hand-tuned—reborn as the legendary Caliber 1041.
Here stands a masterpiece of the highest order.

Ref. 378.0801 — Speedmaster 125 Chronograph

The defining cosmetic hallmark of this limited model lies in its TV case:
a flat, finely brushed frontal surface contrasted by a slender, high-polished bezel.

Beneath the thick mineral crystal, the inner black tachymeter bezel reveals itself—imbued with the very soul of Omega’s first automatic chronograph movement, Caliber 1040.
Its deep-set structure creates remarkable dimensionality, allowing the dial to breathe with depth and presence.

The tritium-filled bar indexes are designed to maximize legibility, while at 3 o’clock, a two-tone grey and black sector clearly distinguishes day and night within the 24-hour display.
At the center, the chronograph seconds hand is joined by the distinctive “airplane” hand—later repurposed as a date pointer in modern Speedmasters—here serving as a minute counter.

Every detail invites the wearer to fully indulge in the authentic status of the vintage Speedmaster.
Without question, this is a truly exceptional piece.
