Omega Speedmaster Automatic Mens Watch 304.30.44.52.01.001 review

Intro: A Moonphase Speedmaster for Daily Wear and Special Moments

Model 304.30.44.52.01.001 refers to the Omega Speedmaster Moonwatch Moonphase Chronograph—a Master Chronometer–certified, automatic chronograph with a photorealistic moonphase display. It blends the Speedmaster’s motorsport DNA with a poetic complication, making it a compelling option if you want one watch that’s technically advanced, visually striking, and robust enough for regular wear.

This configuration is the stainless-steel, black-dial variant on a matching steel bracelet, built around Omega’s Co‑Axial Master Chronometer calibre 9904. If you’ve been weighing a classic Moonwatch against something with more functionality and modern robustness, this reference aims to give you both: the iconic Speedmaster look and a set of complications you’ll use and enjoy.

Quick verdict: The Omega Speedmaster Moonwatch Moonphase Chronograph 304.30.44.52.01.001 is a versatile, enthusiast-grade chronograph that adds a charismatic moonphase and modern Master Chronometer performance without losing the everyday practicality collectors expect from a Speedmaster.

Design & Build

The first impression is unmistakably Speedmaster: a sporty, purposeful case with flowing lyre lugs, a tachymeter bezel, and high-contrast dial. The moonphase chronograph execution adds depth and drama without compromising legibility. The black dial is balanced by two primary sub-dials and a moonphase aperture that acts as a focal point, keeping the layout clean while packing in functionality.

In stainless steel, this watch feels solid and reassuring on the wrist. The case diameter (in Omega literature for this reference) is 44.25 mm—chosen to house the advanced 9904 movement and moonphase module—yet the curved lugs and bracelet integration help it wear more comfortably than the number might suggest for many wrists. The bracelet, with its alternating brushed and polished surfaces, mirrors the case finishing and drapes nicely, aiding comfort for all-day wear.

Material choices are decidedly modern. The tachymeter bezel is typically a scratch-resistant ceramic with an inlaid scale, and the crystals (front and caseback) are sapphire in this family, allowing you to admire the movement while maintaining everyday resilience. Lume-filled hands and hour markers support quick reads in low light, while the contrasting sub-dials and applied details make the dial feel both technical and luxurious.

Ergonomically, chronograph pushers are placed for intuitive operation, and the signed crown provides good purchase for setting time, date/pointer, and moonphase. The bracelet’s clasp offers reliable closure; micro-adjustment options vary by generation and should be checked if on-the-fly sizing is important to you.

Key Features

Master Chronometer Certification (Accuracy and Anti‑Magnetism)

Benefit: Real-world reliability. The calibre 9904 inside the Omega Speedmaster Moonwatch Moonphase Chronograph is Master Chronometer certified by METAS. That means the fully cased watch is tested for precision, power reserve, water resistance, and strong anti-magnetic performance.

Where it helps: Everyday life is full of magnetic fields—from laptop covers and phone speakers to handbag clasps. Master Chronometer certification is designed to maintain accuracy even in these conditions, reducing time drift and the need for frequent adjustment. It’s peace of mind if you rely on your watch to be on time for work, travel, or training.

Co‑Axial Automatic Movement (Calibre 9904)

Benefit: Durable timekeeping tech and convenience. The Co‑Axial escapement is designed to reduce friction compared with traditional lever escapements, which can mean steadier performance over time. The automatic winding means you can wear it and keep it powered without daily winding.

Where it helps: If you rotate a small collection, an automatic movement with a generous power reserve (manufacturer literature for this calibre indicates around 60 hours) makes the watch easier to grab and go after a day or two off. The movement is visible through the sapphire caseback, adding horological interest whenever you take it off.

Moonphase Complication

Benefit: Practical poetry on the wrist. The moonphase display is executed with a photorealistic moon disc, a signature flourish in this model family that draws on NASA imagery. It’s surprisingly useful if you enjoy moonlit hikes, fishing, or photography, where the lunar cycle affects conditions.

Where it helps: Setting the moonphase correctly once and making small periodic adjustments keeps the display accurate. It turns an everyday chronograph into a conversation piece and a small ritual of keeping time.

Dual‑Register Chronograph Layout

Benefit: Intuitive timing. The Omega Speedmaster Moonwatch Moonphase Chronograph uses a bi-compax approach, where the 3 o’clock sub-dial typically combines both elapsed minutes and hours (stacked hands), while the 9 o’clock side supports running seconds and a pointer date hand on many references with calibre 9904.

Where it helps: Stacking the chronograph counters keeps the dial symmetrical and easy to scan at a glance. Timing a workout, rest interval, or coffee brew is straightforward, and longer events—like flights, commutes, or meetings—are covered by the hour totalizer.

Ceramic Tachymeter Bezel

Benefit: Scratch resistance meets heritage design. The tachymeter scale is a core Speedmaster cue. Executed in ceramic, it aims to resist everyday scrapes that would mark an aluminum insert.

Where it helps: If you routinely pass through tight doorways, brush against desks, or travel frequently, ceramic helps the watch retain its “new” look longer. The tachymeter scale is still a fun tool for quick mental math—distance/speed for runners, cyclists, or car enthusiasts.

Sapphire Crystal and Exhibition Caseback

Benefit: Clarity and durability up top; mechanical beauty below. The front sapphire crystal helps resist scratches and keeps the dial crisp. The sapphire caseback lets you view the calibre 9904’s rotor, bridges, and finishing.

Where it helps: Daily wearers appreciate how sapphire stands up to keys and countertops. The exhibition back makes the watch more engaging—especially for owners new to mechanical horology.

Stainless-Steel Bracelet and Clasp

Benefit: Balanced weight and versatility. The steel bracelet provides a coherent, sporty look and is easy to wipe clean. The clasp offers secure closure and, depending on variant, may include adjustment positions for small fit tweaks.

Where it helps: If you live in a climate with temperature swings, you’ll appreciate a bracelet that stays comfortable as your wrist expands and contracts. For even more versatility, the watch pairs well with leather or rubber straps (check lug width and end-link fit).

Performance & Use

Getting the most from the Omega Speedmaster Moonwatch Moonphase Chronograph starts with proper sizing and familiarization.

• Sizing the bracelet: Have the bracelet sized so the watch can’t rotate freely yet isn’t pinching. A good check: you should slide a pinky under the clasp without force. If you plan to switch between straps, note the lug width and spring-bar type for easier changes.

• Winding and setting: If the watch has stopped, give it a dozen or so turns of the crown to kick-start the movement before setting the time. Set the time first, then the pointer date and moonphase. Avoid setting date-related functions during the typical “danger window” (often around 8 p.m.–4 a.m.) to protect the mechanism.

• Using the chronograph: Start/stop with the upper pusher and reset with the lower. For timing workouts or cooking, you’ll likely use the central seconds and the minutes counter most; for longer events, the hour counter comes into play. Practice a few starts and resets to understand the pusher feel.

• Reading the moonphase: The moonphase disc advances incrementally. Once set to the correct moon age, it will stay accurate for a long stretch, requiring occasional fine-tuning. Many owners check an online moonphase calculator the first time they set it; thereafter, small adjustments are quick.

• Everyday wear: The Master Chronometer standard is designed to maintain precision in magnetized, temperature-variable environments—exactly the conditions of daily life. Keep it away from extreme shocks and very strong magnetic sources when possible, and rinse the watch in fresh water after salt exposure if you swap to a strap and head to the coast.

• Maintenance: Like any mechanical chronograph, periodic servicing is advisable to refresh lubricants and ensure water resistance is maintained. Service intervals vary with use; if you notice a big change in accuracy or crown feel, that’s a cue to consult an authorized service center. Store the watch in a dry place and keep warranty and service records together.

Comfort and presence on wrist are part of the story. While this Speedmaster Moonwatch Moonphase Chronograph is a modern, substantial piece, the curved lugs and tapering bracelet help it sit well. Dress it up with a leather strap for formal settings, or keep it on steel for all-weather versatility. The black dial and polished accents let it transition from office to weekend seamlessly.
