Catalogue Essay
Omega’s Speedmaster line is legendary amongst collectors, and today it is one of the most sought-after vintage chronograph wristwatches on the market. Introduced in 1957, the model has gone under various design and technical changes through the years, but it has always retained its reputation for precision timekeeping.

This particular Speedmaster, reference 145.012-67 SP, features “lyre”-style twisted lugs with an asymmetrical case incorporating crown guards and a tachymeter scale on the bezel. The “SP” designation in French indicates the watch was equipped with “special poussoirs”, which in English means “special pushers”, providing greater water resistance than those without the ‘SP’ designation.

What makes the present lot exceptional is the utterly rare “exotic”, matte black dial known as the “racing dial”, with a red handset and bicolor red and white hour indexes. This configuration does not appear often, and there are extremely few examples that have ever appeared publicly. It carries a “two liner” designation with Omega and Speedmaster only, and omits the designation Professional as found on later examples. Also, the “T” does not flank the “Swiss Made” script at the bottom of the dial for tritium, another indication of its early origins. A nearly identical example is shown in the Moonwatch Only book. The colors of the dial and hands are vibrant, and together with the well-preserved condition of the case, make it an exciting addition to any collection of rare sports watches.
Artist Biography
Omega
Swiss • 1848
Omega's rich history begins with its founder, Louis Brandt, who established the firm in 1848 in La Chaux de Fonds. In 1903, the company changed its name to Omega, becoming the only watch brand in history to have been named after one its own movements. A full-fledged manufacturer of highly accurate, affordable and reliable watches, its sterling reputation enabled them to be chosen as the first watch company to time the Olympic Games beginning in 1932. Its continued focus on precision and reliability ultimately led their Speedmaster chronograph wristwatch to be chosen by NASA in 1965 — the first watch worn on the moon.
Key models sought-after by collectors include their first, oversized water-resistant chronograph — the reference 2077, early Speedmaster models such as the CK 2915 and 2998, military-issued versions of the Seamaster and oversized chronometer models such as those fitted with their prestigious caliber 30T2Rg.
