The Omega Speedmaster Professional. The name conjures images of lunar dust, the vast expanse of space, and a legacy of unwavering reliability. More specifically, the mention of "Hesalite" evokes a deeper connection to this iconic timepiece, a connection forged not just in steel and precision engineering, but in the very fabric of human history. Three astronauts, Neil Armstrong, Buzz Aldrin, and Michael Collins, each officially equipped with an OMEGA Speedmaster Professional with its distinctive Hesalite crystal, embarked on a journey that would forever etch the watch into the annals of human achievement. This article delves into the enduring appeal of the Omega Speedmaster Professional Hesalite, exploring its history, its technical specifications (including the specific reference number 311.30.42.30.01.005), its various price points, and the ongoing debate surrounding Hesalite versus sapphire crystals.
The Moonwatch and its Hesalite Crystal: A Match Made in Space
The choice of Hesalite, a type of acrylic crystal, over sapphire for the original Speedmaster Professional was not a matter of chance. While sapphire offers superior scratch resistance, Hesalite possessed certain advantages crucial for the harsh conditions of spaceflight. Its lower density made it lighter, a significant consideration for the weight constraints of a space mission. More importantly, in the event of impact, Hesalite would shatter into relatively blunt pieces, minimizing the risk of sharp fragments causing injury to the wearer. This safety feature proved invaluable, and the decision to utilize Hesalite became synonymous with the watch's legendary robustness and reliability. The impact resistance of Hesalite, coupled with its ability to withstand extreme temperature fluctuations, solidified its place as the quintessential material for the Speedmaster Professional destined for the moon.
The Omega Speedmaster Professional Hesalite, particularly the reference number 311.30.42.30.01.005, represents a direct lineage to the timepieces worn on the Apollo 11 mission. This specific reference boasts the classic Speedmaster design elements: the iconic tachymeter bezel, the distinctive sub-dials, and the prominent Hesalite crystal. Its manual-winding Calibre 1861 movement, a direct descendant of the movement that powered the watches on the moon, ensures a faithful continuation of the original's mechanical precision and heritage. The 311.30.42.30.01.005 is often sought after by collectors precisely because of its adherence to this historical legacy.
Omega Speedmaster Hesalite Replacement Cost: A Matter of Maintenance
While Hesalite's durability is remarkable, it is not impervious to damage. Scratches are inevitable with regular wear, and occasionally, more significant damage may necessitate a replacement. The Omega Speedmaster Hesalite replacement cost varies depending on the authorized service center and the specific model. It's crucial to seek repairs only through authorized channels to ensure the use of genuine Omega parts and maintain the watch's warranty. The cost is generally less than replacing a sapphire crystal, reflecting the inherent cost difference between the two materials. However, the relatively lower replacement cost of Hesalite is often cited as one of its advantages, particularly for those who appreciate the watch's vintage aesthetic and are willing to accept the trade-off in scratch resistance.
