Omega Speedmaster Broad Arrow White Dial 'Moonphase' 3575.20

The Omega Speedmaster Broad Arrow “Moonphase” Ref. 3575.20.00 is one of the most distinctive and underappreciated variations of the Speedmaster lineup, blending the classic Moonwatch DNA with additional complications and a more refined aesthetic. Produced in the early 2000s (approx. 2000–2005), this model features a 42 mm stainless steel case paired with an elegant ivory/white dial accented by blued steel hour markers and Broad Arrow hands—a direct nod to the original 1957 Speedmaster design.

What sets this reference apart is its complex dial layout, which adds both a moonphase and date complication to the traditional chronograph. The moonphase display is integrated into the 12-hour counter at 6 o’clock, giving the watch a total of four sub-dials, while maintaining a surprisingly balanced look. The watch also features a tachymeter bezel made of 18k white gold, elevating it beyond the standard steel Moonwatch variants and giving it a subtle luxury edge.

Inside, the watch is powered by the Omega Calibre 1866, a manual-winding chronograph movement derived from the Moonwatch’s Calibre 1861 but modified to support the moonphase and date functions. It offers around 48 hours of power reserve and retains the traditional hand-wound experience that Speedmaster enthusiasts appreciate. The watch is fitted with a sapphire crystal, distinguishing it from hesalite Moonwatch models, and typically comes on a steel bracelet or leather strap.

Founded in 1848 by Louis Brandt in Switzerland, Omega has grown into one of the most respected and innovative names in watchmaking. The brand’s early focus on precision earned it accolades at international observatories and competitions, setting the stage for decades of horological achievement. Omega became the official timekeeper for the Olympic Games in 1932, and in 1969, the Speedmaster Professional—nicknamed the "Moonwatch"—made history as the first watch worn on the lunar surface during NASA’s Apollo 11 mission. Omega’s innovations continued with the introduction of the Co-Axial escapement in the late 1990s, a groundbreaking movement that dramatically reduced friction and improved long-term accuracy.

Omega’s lineup showcases a wide range of iconic models that reflect the brand’s legacy and versatility. The Seamaster, introduced in 1948, is a favorite among divers and famously worn by James Bond since 1995’s GoldenEye, blending technical capability with cinematic cool. The Speedmaster remains one of the most storied chronographs in existence, while the Constellation is known for its refined design and chronometric precision. The De Ville collection offers a more elegant, dress-focused aesthetic, often featuring high-end complications and meticulous finishing. Omega continues to lead with innovations like Master Chronometer certification, METAS testing, and antimagnetic technology—ensuring that its watches are not just beautiful, but built for the demands of modern life.
