A Blast from the Past: The Allure of Acrylic Crystals
Early Omega Speedmasters, particularly those from the pre-professional era and some early Professional models, utilized acrylic crystals. These crystals were significantly less scratch-resistant than modern sapphire crystals, but they possessed a unique charm and character. Their softer nature meant they could develop a pleasing patina over time, reflecting the watch's history and the wearer's journey. Scratches, while aesthetically less desirable to some, told a story, acting as a testament to the watch's adventures. The gentle dome of the acrylic crystal also contributed to the overall vintage aesthetic, a look highly sought after by collectors today. Furthermore, acrylic crystals were relatively inexpensive to produce and replace, making them a practical choice for a tool watch intended for robust use.
The appeal of an acrylic crystal on a vintage or restored Speedmaster lies in its authenticity. For those seeking a historically accurate restoration, replacing a damaged crystal with another acrylic piece is crucial. It maintains the integrity of the watch and preserves its historical context. The slightly warmer, more yellowish hue that acrylic develops over time also contributes to the vintage character, often preferred by enthusiasts who value the watch's history.
The Rise of Hesalite: Omega's Iconic Choice
While acrylic crystals were used early on, Omega's choice of Hesalite (a type of polymethyl methacrylate or PMMA) crystal for the Speedmaster Professional solidified its place in horological history. Hesalite, while still technically an acrylic, offers superior scratch resistance compared to standard acrylic. This enhancement is crucial for a watch destined for harsh environments, as was the case during the Apollo missions. Hesalite’s ability to withstand the rigors of space travel cemented its reputation and enduring legacy within the Speedmaster community.
The choice of Hesalite wasn't purely about durability. It also possessed a crucial characteristic: resilience against shattering. In the event of an impact, Hesalite tends to crack or chip rather than shattering into numerous fragments, mitigating the risk of damage to the watch movement. This safety feature, particularly important in a tool watch, further solidified Hesalite's position as the preferred crystal for the Speedmaster Professional.
