Just picked up a Speedmaster Professional 3572.50.00 (Hesalite Sandwich) from the 90s that needs its plexiglass replaced. Can someone point me in the direction of where to…? This seemingly simple question opens a door to a world of considerations for owners of vintage and modern Omega Speedmaster Professional watches featuring the iconic Hesalite crystal. Replacing a Hesalite crystal isn't as straightforward as it might initially appear, involving a blend of technical skill, sourcing genuine parts, and understanding the nuances of this particular material. This article will delve deep into the process, cost, and considerations surrounding Omega Speedmaster Hesalite crystal replacement.
Understanding the Omega Speedmaster Professional Hesalite Crystal
Before diving into the replacement process, it's crucial to understand why Hesalite is so significant to the Speedmaster's legacy and what makes its replacement different from a simple sapphire crystal swap. The Speedmaster Professional, famously worn on the moon, utilizes a Hesalite crystal, a type of acrylic plastic, for several key reasons:
* Superior Shock Resistance: Hesalite is significantly more resistant to shattering than sapphire. While it can scratch, it's less prone to catastrophic failure from impacts, a critical feature for a watch designed for rugged use. This resilience is a key factor in the watch's enduring reputation for durability.
* Authenticity: The use of Hesalite is inextricably linked to the historical significance of the Speedmaster. Replacing it with sapphire undermines the watch's connection to its heritage and potentially diminishes its value for collectors.
* Unique Appearance: Hesalite possesses a distinct optical clarity and slightly warmer tone compared to sapphire. This contributes to the Speedmaster's unique aesthetic appeal. Many enthusiasts prefer the vintage look and feel that Hesalite offers.
* Easier and Cheaper Repair: While scratching can be a concern, minor scratches on Hesalite can often be buffed out, making repairs less expensive and less invasive than replacing a sapphire crystal.
Omega Speedmaster Professional Hesalite: Sourcing a Replacement Crystal
Finding a genuine Omega Hesalite crystal is paramount. Using a non-genuine replacement can compromise the watch's water resistance and potentially damage the movement. Here's where you can look:
* Omega Authorized Service Centers: This is the most reliable option. Omega service centers have access to genuine parts and trained technicians who can ensure a proper installation. However, this option is typically the most expensive. Expect to pay a premium for both the part and the labor.
* Authorized Omega Dealers: Some authorized dealers may stock Hesalite crystals or be able to order them for you. Check with your local dealer to see if they can assist with the replacement. The cost might be slightly less than a full service center repair, but still higher than independent watchmakers.
* Reputable Independent Watchmakers: Experienced watchmakers specializing in vintage Omega watches are another viable option. They often have access to genuine or high-quality replacement crystals and can perform the replacement at a potentially lower cost than Omega's service centers. However, it's crucial to find a highly reputable and skilled watchmaker with a proven track record of working on Omega Speedmasters. Always ask for references and check online reviews.
* Online Retailers (Caution Advised): Several online retailers sell watch parts, including Hesalite crystals. However, exercise extreme caution when purchasing from online sources. Ensure the seller is reputable and can guarantee the authenticity of the crystal. Counterfeit parts are prevalent, and using a fake crystal can void any warranty and potentially harm your watch.
