The Omega Speedmaster Professional. A name synonymous with legendary space exploration, iconic design, and enduring horological excellence. This chronograph, famously worn on the moon, holds a special place in the hearts of watch enthusiasts worldwide. But amidst its storied history and robust construction, a crucial point often gets overlooked, and sometimes even misrepresented: its water resistance. While the watch is indeed advertised as "water resistant," understanding the nuances of this claim is crucial for preserving this valuable timepiece. This article delves deep into the topic, addressing common questions and misconceptions surrounding the Omega Speedmaster Professional's water resistance, exploring its capabilities and limitations, and providing guidance on responsible ownership.
Is the Omega Speedmaster Waterproof?
The short answer is no. The Omega Speedmaster Professional, despite its water-resistant designation, is emphatically *not* waterproof. This distinction is critical. "Waterproof" implies complete immunity to water ingress under any circumstance. "Water resistant," however, signifies a degree of protection against water damage under specific conditions. The Speedmaster Professional's water resistance is rated, depending on the specific model and year of production, typically at 50 meters (165 feet) or 30 meters (100 feet). This rating does *not* mean the watch can withstand submersion at that depth. Instead, it indicates a resistance to splashes and brief immersion under controlled conditions. Any prolonged exposure to water, especially under pressure, risks damaging the watch's internal components.
The marketing of the watch as "water resistant" often leads to misunderstandings. The relatively low water resistance rating, when compared to modern dive watches, is a deliberate design choice. The Speedmaster's intricate movement, with its exposed pushers, requires a different approach to sealing than a fully waterproof, pressure-resistant dive watch. The focus is on reliability and functionality in its primary design purpose, not deep-sea exploration.
Omega Speedmaster Moonwatch Water Resistance:
The Omega Speedmaster Moonwatch, a specific variant of the Professional model, shares the same fundamental limitations regarding water resistance. Its design prioritizes robustness and functionality in extreme conditions, but not necessarily prolonged underwater exposure. The original Speedmaster worn on the moon boasted a water resistance rating even lower than its modern counterparts. While modern models might have slightly improved seals and gaskets, the fundamental design remains relatively unchanged, and the water resistance rating remains modest. The moonwatch's legacy is not built on underwater performance, but on its performance in the vacuum of space and the harsh conditions of the lunar surface. Therefore, treating it as a dive watch would be a gross misunderstanding of its capabilities and a significant risk to its longevity.
Omega Speedmaster Lug to Lug:
The lug-to-lug measurement (the distance between the watch lugs where the straps attach) is an important consideration for fit and comfort. The Omega Speedmaster Professional's lug-to-lug measurement varies slightly depending on the case size and model, typically falling within the range of 47-50mm. This relatively large size contributes to its bold and iconic appearance, but it's crucial to consider this dimension when assessing its suitability for your wrist.
Omega Speedmaster Automatic Tachymeter:
Many Omega Speedmaster Professional models feature an automatic movement and a tachymeter bezel. The tachymeter scale allows for the measurement of speed based on the time it takes to cover a known distance. This functionality, however, is entirely unrelated to the watch's water resistance. The automatic movement, while contributing to the watch's overall functionality, doesn't influence its ability to withstand water exposure. The tachymeter's accuracy is also not impacted by water exposure, provided the watch itself remains undamaged.
