Omega Speedmaster Moonphase Yellow Gold & Silver-White Dial

The Speedmaster Moonphase ref. 304.63.44.52.02.001 combines the iconic Speedmaster chronograph design with an elaborate moonphase complication and an 18K yellow gold case. Its opaline silvery dial provides a refined contrast against the warm gold case and black ceramic bezel.

The 44.25 mm timepiece is powered by the OMEGA Co-Axial Master Chronometer Calibre 9905, a self-winding movement certified by METAS. It provides approximately 60 hours of power reserve and incorporates chronograph, date, small-seconds, and moonphase functions.

18K Yellow Gold Case

The Omega Speedmaster Yellow Gold features an 18K yellow-gold case measuring 44.25 mm in diameter. The case combines polished and satin-finished surfaces to create visual contrast while maintaining the luxurious character expected from a precious-metal Speedmaster.

Its substantial proportions give the watch a strong wrist presence while preserving the technical character of the Speedmaster collection.

Silver-White Opaline Dial

The standout feature of this Omega Silver Dial Watch is its opaline silvery dial. The light silver-white appearance creates an elegant contrast against the yellow-gold case.

The dial features diamond-polished 18K yellow-gold indexes and hands, along with luminous details for improved legibility.

Moonphase Display

The Speedmaster Moonphase incorporates a detailed moonphase display at 6 o’clock. The moon disc is crafted in 18K yellow gold and hand-engraved, with enamel and silver powder used to create the appearance of the lunar surface and surrounding stars.

This intricate display adds an astronomical dimension to the traditional Speedmaster chronograph layout.

Black Ceramic Bezel with Ceragold™ Tachymeter

The watch is fitted with a black ceramic bezel ring featuring a Ceragold™ tachymeter scale. The dark bezel creates a strong visual contrast against the yellow-gold case and silver-white dial.

The tachymeter scale retains one of the defining technical elements of Speedmaster chronograph design while contributing to the watch’s sporty character.

Co-Axial Master Chronometer Calibre 9905

At the heart of the watch is the OMEGA Calibre 9905, a self-winding Co-Axial Master Chronometer movement. It is METAS certified and designed to provide high levels of precision, magnetic resistance, and performance.

The movement operates with an approximately 60-hour power reserve and can be viewed through the transparent sapphire caseback.

Chronograph and Date Functions

Beyond its moonphase display, the watch provides a complete set of practical functions including hours, minutes, small seconds, chronograph timing, date, and tachymeter functionality.

The two sub-dials combine multiple functions, with the 9 o’clock sub-dial incorporating date and small seconds while the opposite register handles chronograph timing.

Black Leather Strap

The warm yellow-gold case is paired with a black leather strap, creating a sophisticated contrast with the silver-white dial and black ceramic bezel.

The documented reference uses an alligator leather surface with a non-grained calf-leather underside and an 18K yellow-gold foldover clasp.

Sapphire Crystal and Transparent Caseback

The Omega Speedmaster Moonphase uses scratch-resistant sapphire crystal with anti-reflective treatment on both sides. A transparent sapphire caseback allows the mechanical Calibre 9905 to remain visible.

The combination provides both practical protection and an opportunity to appreciate the movement’s finishing and mechanical architecture.

100 Metres Water Resistance

The reference 304.63.44.52.02.001 is rated to 10 bar / 100 metres / 330 feet of water resistance. This provides useful everyday protection while the watch remains primarily designed as a luxury chronograph and mechanical timepiece.
