Omega Speedmaster Moonphase Blue Dial

The Speedmaster Moonphase brings together the recognizable Speedmaster chronograph design with an intricate astronomical complication. This stainless-steel configuration combines a striking blue dial, blue ceramic bezel, and matching blue leather strap for a cohesive and sophisticated appearance.

Reference 304.33.44.52.03.001 measures 44.25 mm and is powered by OMEGA’s self-winding Co-Axial Master Chronometer Calibre 9904.

Stainless Steel Case

The stainless-steel case provides the classic foundation for this Omega Speedmaster Moonphase. At 44.25 mm, the case offers a substantial wrist presence while retaining the familiar Speedmaster silhouette.

The case is paired with an exhibition-style transparent caseback, allowing the wearer to view the automatic movement.

Blue Sun-Brushed Dial

The blue dial is the defining visual feature of this Speedmaster Moonphase. Its rich blue color gives the watch a sporty yet sophisticated appearance, while the contrasting indexes and hands maintain clear legibility.

The dial incorporates the chronograph displays together with the moonphase indication at 6 o’clock, creating a technically detailed appearance.

Moonphase Display

The moonphase complication gives this Speedmaster an additional dimension beyond traditional chronograph functionality. The lunar display provides a detailed representation of the Moon and serves as the centerpiece of the lower portion of the dial.

OMEGA’s implementation uses a microstructured metallic crystal disc to create a highly detailed lunar appearance.

Co-Axial Master Chronometer Calibre 9904

At the heart of the Speedmaster Moonphase is OMEGA’s Calibre 9904, a self-winding Co-Axial Master Chronometer movement.

The movement provides approximately 60 hours of power reserve and combines chronograph, date, tachymeter, small seconds, and moonphase functions. It is also designed to resist magnetic fields up to 15,000 gauss.

Blue Ceramic Bezel

The blue ceramic bezel complements the dial and incorporates a Liquidmetal™ tachymeter scale. The tachymeter is an iconic Speedmaster feature and reinforces the watch’s connection with performance-oriented chronograph design.

The blue-on-blue configuration creates a particularly cohesive appearance across the front of the watch.

Chronograph Functionality

The chronograph layout gives the Omega Speedmaster Moonphase its recognizable instrument-inspired character. The watch combines timing functions with the moonphase display, creating a more technically sophisticated alternative to a conventional three-hand timepiece.

The dial incorporates a 12-hour/60-minute chronograph recorder and small-seconds/date indications.

Blue Leather Strap

The matching blue leather strap completes the monochromatic blue aesthetic. It gives the watch a more refined appearance than a traditional metal bracelet while complementing the blue dial and ceramic bezel.

The documented reference uses a blue leather strap with a deployment clasp and a 21 mm lug width.

Sapphire Crystal

The watch is fitted with scratch-resistant sapphire crystal featuring anti-reflective treatment. This helps provide clear visibility of the blue dial while offering strong resistance to everyday scratching.

The transparent caseback also allows the mechanical Calibre 9904 to be viewed from the rear.
