I. The Flat-Lay That Divides The Room

The collage is simple but potent. On the left, the Omega Speedmaster First Omega in Space (FOiS): a 39.7mm steel case, a deep blue dial with a pulse bezel, and the manual-wind caliber 1861 (in older versions) or 3861 (in newer). On the right, the Zenith Chronomaster Original: a 38mm steel case, a tri-color gray, blue, and silver dial, and the automatic El Primero 3600 beating at 36,000 vibrations per hour. Two chronographs, both legendary, both available for under $8,000. And yet, they could not be more different.

The FOiS is a tribute to the Speedmaster that astronaut Wally Schirra wore on the Mercury-Atlas 8 mission in 1962—the first Omega in space. It is not the Moonwatch. It is the pre-Moon watch. The dial is symmetrical, without the typical Speedmaster crown guards. The bezel is a tachymètre scale, but the outer ring is polished steel instead of black aluminum. It is elegant, vintage, and slightly dressy.

The Zenith Chronomaster Original is a revival of the 1969 A386, the first watch to house the El Primero movement. The tri-color dial is instantly recognizable: gray, blue, and silver subdials, with a date window at 4:30. The movement is the modern El Primero 3600, which measures 1/10th of a second. The chronograph hand makes one full rotation every 10 seconds, a mesmerizing sight.

This essay is a head-to-head comparison of these two icons. We will look at the history, the design, and the wearing experience. We will also consider opposing views, because neither watch is perfect, and we will leave you with a few questions about which one belongs on your wrist.

 

II. The Contenders: History And Heritage

Before the comparison, the stories.

**Omega Speedmaster FOiS:** The “First Omega in Space” is not the Moonwatch. The Moonwatch (the Speedmaster Professional) was certified by NASA in 1965. The FOiS is based on the 2998 reference, which Schirra wore on his Mercury flight in 1962. The watch has a straight lug case (no crown guards), a steel bezel with a black anodized aluminum insert (later versions have a ceramic bezel), and a hesalite crystal (or sapphire on some versions). The movement is the manual-wind 3861, with a coaxial escapement and a 50-hour power reserve. The dial is a deep blue (“Cobalt Chrome”), with white hands and indices. The FOiS is a tribute to a specific moment in space history, not to the moon landing.

**Zenith Chronomaster Original:** The El Primero movement was a revolution. In 1969, Zenith released the first automatic chronograph movement, beating at 36,000 vibrations per hour. The A386 had a tri-color dial, a date window at 4:30, and a tachymètre bezel. The Chronomaster Original is a faithful reissue, with a 38mm case, a sapphire crystal, and the El Primero 3600. The movement has a 60-hour power reserve and a column wheel. The tri-color dial is the star: light gray subdial at 3, dark blue at 6, and silver at 9. The watch is a celebration of high-frequency precision.

 

III. Side-By-Side: Design, Wearability, And Value

The flat-lay reveals the differences immediately.

**Case:** The FOiS is 39.7mm wide, 48mm lug-to-lug, and 14mm thick. The Zenith is 38mm wide, 47mm lug-to-lug, and 13mm thick. Both are comfortable on a 6.5-inch wrist, but the Zenith wears smaller and thinner. The FOiS has a slightly more substantial presence.

**Dial:** The FOiS’s blue dial is elegant and changes with the light. The Zenith’s tri-color dial is busy but distinctive. Legibility goes to the FOiS: the white hands and indices stand out clearly. The Zenith’s silver hands against the gray subdial can be harder to read at a glance.

**Bezel:** The FOiS has a steel bezel with a black ceramic insert. The Zenith has a steel bezel with a black aluminum insert. Both are tachymètres. The FOiS’s ceramic bezel is more scratch-resistant.

**Movement:** The FOiS’s manual-wind 3861 is a modern classic, with a coaxial escapement and a 50-hour power reserve. The Zenith’s automatic El Primero 3600 is a high-frequency marvel, with a 60-hour power reserve and a 1/10th-second chronograph. The manual-wind is a ritual; the automatic is a convenience.

**Price:** The FOiS is around $7,000 on the bracelet. The Zenith is around $8,000 on the bracelet. Both are in the same range, but the Zenith is slightly more expensive.

 

IV. Three Honest Oppositions: Why Neither Watch Is Perfect

For every collector who loves the FOiS or the Zenith, there is another who finds a fatal flaw. Here are three reasonable objections, mixed between both watches.

 

Opposition One: “The FOiS Is Not The ‘Real’ Moonwatch”

The first objection is about the FOiS. It is called the “First Omega in Space,” but it did not go to the moon. It went to low Earth orbit. For collectors who want the Moonwatch, the FOiS is a compromise. It is a dressier Speedmaster, but it lacks the history of the Professional. And the blue dial, while beautiful, is not the classic black.

The counter-argument is that the FOiS has its own history. It is the watch that started Omega’s relationship with NASA. It is more elegant than the Professional, and the blue dial is a welcome change. The suspense is whether the FOiS will ever be accepted as a true classic or remain a niche variant.

 

Opposition Two: “The Zenith’s Date Window Ruins The Dial”

The second objection is about the Zenith. The date window at 4:30 is a constant source of debate. Some collectors find it charming, a signature of the original A386. Others find it disruptive, a blemish on an otherwise beautiful dial. A no-date version, they argue, would be perfect.

The counter-argument is that the date window is historically accurate, and it is placed to preserve symmetry. And the date disc is color-matched to the dial (white on the silver subdial), making it less intrusive. The suspense is whether Zenith will ever release a no-date version of the Chronomaster Original.

 

Opposition Three: “Both Watches Are Too Expensive For What They Are”

The third objection is financial. At $7,000–$8,000, both watches are competing with the Tudor Black Bay Chrono ($5,000), the Longines Spirit Zulu Time ($4,000), and even a pre-owned Rolex Daytona (if you are lucky). Critics argue that the FOiS and the Zenith are overpriced for their movements and materials. You are paying for heritage, not for value.

The counter-argument is that both watches are in-house, with unique movements and deep histories. The FOiS’s 3861 is a modern masterpiece, and the Zenith’s El Primero is legendary. The price reflects the engineering and the exclusivity. The suspense is whether the secondary market will agree.

 

V. The Unseen Supply Chain: From Manufactories To Silicone Bands And Pink Dials

Both Omega and Zenith are Swiss brands with their own Watches Manufactory facilities. Omega’s factory in Bienne produces the 3861 movement; Zenith’s manufacture in Le Locle produces the El Primero. But both brands rely on external suppliers for cases, dials, and hands. The global supply chain is complex, but the final assembly and quality control happen in Switzerland.

The straps on both watches are steel bracelets. But many owners will want to experiment. A Wholesale Silicone Watch Bands would be a practical choice for a sports chronograph: silicone is waterproof, comfortable, and available in any color. A blue silicone strap on the FOiS would match the dial. A black silicone strap on the Zenith would be stealthy.

And what of dial colors? The FOiS has a blue dial; the Zenith has a tri-color dial. But imagine a limited edition with a Custom Pink Watch Dials—a soft, blush pink. A pink-dialed Speedmaster or El Primero would be a shock, but it would also be a collector’s item. The supply chain for custom dials exists; the only question is whether either brand will take the risk.

 

VI. The Unanswered Questions: Which Chronograph Wins Sunday Morning?

After studying the collage, wearing both (in imagination), and reading the debates, I am left with three questions that every collector must answer for themselves.

**First:** Do you prefer manual-wind or automatic? The FOiS requires winding. The Zenith is automatic. If you rotate watches daily, the automatic is more convenient. If you enjoy the ritual, the manual-wind is more satisfying.

**Second:** Is the tri-color dial too busy for you? Some collectors love it. Others find it overwhelming. The FOiS’s blue dial is cleaner and more legible. Your choice will reflect your tolerance for visual complexity.

**Third:** And most personally—which history resonates more? The space history of the FOiS? Or the high-frequency precision of the Zenith? There is no wrong answer. But your answer will guide your purchase.

 

VII. The Collage Verdict

We began with a collage: the Omega Speedmaster FOiS and the Zenith Chronomaster Original, side by side. We have examined their histories, designs, and value. We have listened to three objections, traced the supply chain of watch manufactories, silicone bands, and pink dials, and left three questions unanswered.

The Omega Speedmaster FOiS and the Zenith Chronomaster Original are not watches for everyone. They are not for the collector who needs a dive bezel or a date window at 3 o’clock. They are not for the person who finds manual-winding a chore or tri-color dials distracting. But they are for anyone who appreciates the art of the chronograph, the beauty of a well-proportioned dial, and the joy of wearing a piece of history.

The Sunday morning showdown has no winner. Only a choice. The question is which one you will make.
