The Omega Speedmaster Professional, a watch synonymous with lunar exploration and enduring style, is instantly recognizable. But beyond its iconic design and rich history lies a crucial detail often overlooked: its crystal. While many modern watches utilize sapphire crystals for their superior scratch resistance, the Speedmaster Professional, in its truest form, boasts a Hesalite crystal. This seemingly minor detail speaks volumes about the watch's heritage, performance, and the enduring dedication of Omega to its legacy. This article delves into the world of the Omega Speedmaster and its Hesalite crystal, exploring its properties, its replacement, and its enduring appeal to Speedmaster enthusiasts.
Omega Speedmaster Crystal Replacement: The Importance of Authenticity
The crystal, that seemingly delicate dome of glass protecting the watch face, is a critical component. Its replacement, therefore, requires careful consideration. While many aftermarket options exist, using genuine Omega Hesalite is crucial for maintaining the watch's authenticity and performance characteristics. A poorly fitted or inferior replacement crystal can compromise water resistance, impact resistance, and even the overall aesthetics of the watch. Furthermore, using a non-genuine part may void any warranty you may have on your watch.
Finding a genuine Omega Speedmaster crystal replacement involves locating an authorized Omega service center or a reputable watch repair specialist with experience in working with vintage and modern Speedmasters. These professionals possess the necessary tools, expertise, and access to genuine Omega parts to ensure a flawless and safe replacement. Attempting a DIY replacement is strongly discouraged, as improper installation can lead to irreversible damage to the watch.
Omega Speedmaster Replacement: Beyond the Crystal
While this article focuses primarily on the crystal, it's important to understand that crystal replacement is just one aspect of potential Speedmaster maintenance and repair. Omega Speedmasters, particularly older models, may require other components replaced over time. This could include movement servicing, dial restoration, bezel replacement, or even case refurbishment. Finding a qualified watchmaker experienced with Omega Speedmasters is crucial for these more extensive repairs. These specialists possess the knowledge and tools necessary to work on the intricate mechanisms of the watch, ensuring its continued accuracy and longevity.
Omega Speedmaster Hesalite Crystal: The Unique Properties of a Classic
Omega uses the term "Hesalite" to describe the material used for the Speedmaster's crystal. But what exactly is Hesalite? It's a transparent thermoplastic, a type of acrylic, specifically a polymethyl methacrylate (PMMA) resin. Unlike sapphire, which is a crystalline mineral, Hesalite possesses unique properties that have contributed to its enduring presence on the Speedmaster.
One key advantage of Hesalite is its relative resistance to shattering. While it's not as scratch-resistant as sapphire, Hesalite is less prone to shattering upon impact. This was a crucial factor in the Speedmaster's selection for the Apollo missions. The harsh conditions of space travel, including the potential for micrometeorite impacts, demanded a crystal that would withstand significant stress without fragmenting into dangerous shards. Hesalite's ability to withstand impacts, even if resulting in scratches, made it a safer and more reliable choice than sapphire in the context of space exploration.
Furthermore, Hesalite possesses a slightly warmer, more vintage aesthetic compared to the often cooler, clearer look of sapphire. This subtle difference in appearance contributes to the classic and timeless appeal of the Speedmaster Professional. The slightly yellowish tint of Hesalite, especially in older watches, adds to the character and patina that many collectors find so desirable.
