Omega Moonwatch Reference Numbers

The Omega Moonwatch, also known as the Omega Speedmaster Professional, holds a special place in horology due to its rich history and association with space exploration. Introduced in 1957, the Speedmaster became the first watch worn on the moon during the Apollo 11 mission in 1969. Over the decades, Omega has released numerous variations and limited editions of the Moonwatch, each with its own reference number. This article explores the key reference numbers associated with the Omega Moonwatch, delving into their significance, features, and collectability.

Historical Background of the Omega Moonwatch

The Omega Speedmaster Professional's journey to the moon is a tale of precision, reliability, and endurance. Originally designed for motorsports, the Speedmaster was adopted by NASA after rigorous testing, becoming the official watch for its astronauts. The reference number 105.012 is particularly significant, as it was the model worn by Buzz Aldrin during his historic moonwalk. This reference number is one of the most sought-after by collectors due to its direct connection to the Apollo 11 mission.

Key Reference Numbers and Their Significance

1. 105.003 ("Ed White")
   The 105.003 is known as the "Ed White" model, named after the astronaut who wore it during the first American spacewalk in 1965. This reference features straight lugs without crown guards and a symmetrical case, distinguishing it from later models. The 105.003 is highly prized among collectors for its vintage appeal and historical significance.

2. 105.012 ("Moonwatch")
   The 105.012 is perhaps the most iconic of all Speedmaster references, earning the nickname "Moonwatch." It was the first model to feature twisted lugs and an asymmetric case, designed to protect the crown and pushers. This reference was worn by astronauts during several Apollo missions, including the legendary Apollo 11.

3. 145.012
   The 145.012 was produced concurrently with the 105.012 and shares many of its features, including the twisted lugs and asymmetric case. However, it introduced the new Caliber 321 movement, which has become legendary in its own right. The 145.012 is notable for being the last reference to use the Caliber 321 before Omega transitioned to the Caliber 861 in subsequent models.

4. 145.022
   Introduced in 1968, the 145.022 marked a significant shift for the Speedmaster, as it was the first model to use the Caliber 861 movement. The 861 offered improved reliability and easier servicing, making it a practical choice for astronauts and collectors alike. The 145.022 is often seen as a bridge between the vintage era of the Speedmaster and its modern iterations.

5. 311.30.42.30.01.005 ("Sapphire Sandwich")
   A more contemporary reference, the 311.30.42.30.01.005, often referred to as the "Sapphire Sandwich," features a sapphire crystal on both the front and back of the watch, allowing a clear view of the movement. This model is popular among those who appreciate both the aesthetic and technical aspects of horology.

6. 311.30.42.30.01.006 ("Hesalite")
   For purists, the 311.30.42.30.01.006 retains the traditional hesalite crystal, similar to the material used in the original Moonwatch models. This reference is often favored by those who seek a closer connection to the Speedmaster's historical roots.

Limited Editions and Special Releases

Omega has also produced numerous limited editions and special releases of the Moonwatch, each with its unique reference number. These models often commemorate significant anniversaries, space missions, or partnerships. Some notable examples include:

• 311.30.42.30.99.001 ("Apollo 11 50th Anniversary")
  Released to commemorate the 50th anniversary of the Apollo 11 mission, this limited edition features a distinctive gold and black color scheme, along with a unique engraving on the case back. The reference number for this model highlights its exclusivity and collectible nature.

• 311.30.42.30.99.002 ("Silver Snoopy Award")
  The "Silver Snoopy Award" edition celebrates the Speedmaster's role in the safe return of the Apollo 13 crew. This model features a depiction of Snoopy on the dial, along with a case back that glows in the dark. The reference number signifies its place as one of the more whimsical and sought-after Speedmasters.

• 311.63.42.30.02.001 ("Apollo 17 40th Anniversary")
  Honoring the final moon landing mission, the Apollo 17 40th Anniversary model is another collector's favorite. Its reference number is often associated with its limited production run and the unique design elements that pay tribute to the mission.

Understanding Omega Reference Numbers

Omega reference numbers are typically composed of a series of digits that convey specific information about the watch, such as the model, material, and movement. For example, the reference number 311.30.42.30.01.005 can be broken down as follows:

• 311: Indicates the model family (in this case, the Speedmaster).
• 30: Refers to the material (stainless steel).
• 42: Denotes the case size (42mm).
• 30: Represents the type of movement (manual-winding chronograph).
• 01: Specifies the dial type.
• 005: Identifies the specific version within the model line.

This system allows collectors and enthusiasts to quickly identify and compare different models within the Speedmaster range.

The Collectability of Moonwatch References

The collectability of Omega Moonwatch references is influenced by several factors, including rarity, historical significance, condition, and provenance. For example, early references like the 105.003 and 105.012 are highly sought after due to their direct association with NASA's space missions. Limited editions and special releases, such as the Apollo 11 50th Anniversary model, also command high prices due to their exclusivity and unique design features.

Collectors often seek out models with original parts, including the dial, hands, and bezel, as these elements contribute to the watch's authenticity and value. Additionally, watches with documented history, such as being owned by an astronaut or having been worn during a specific mission, are considered especially desirable.

Conclusion

The Omega Moonwatch is more than just a timepiece; it is a symbol of human achievement and exploration. Its various reference numbers represent different chapters in the Speedmaster's storied history, each with its own unique appeal to collectors and enthusiasts. Whether you are drawn to the historical significance of the 105.012, the technical innovation of the 145.022, or the modern sophistication of the "Sapphire Sandwich," the Moonwatch offers something for everyone. As you explore the world of Omega Speedmasters, understanding the reference numbers will enhance your appreciation for these iconic watches and guide you in building a meaningful collection.
