The Omega Speedmaster, particularly the iconic Professional Moonwatch, holds a special place in horological history. Its robust design and legendary status as the first watch worn on the moon have cemented its position as a coveted timepiece for collectors and enthusiasts alike. However, like any watch, the Speedmaster is susceptible to wear and tear, and one of the most common components requiring replacement is the crystal. This article delves into the complexities of Omega Speedmaster crystal replacement, covering various models, crystal types (primarily Hesalite and sapphire), the process itself, and considerations for choosing a replacement.
Understanding Omega Speedmaster Crystal Types:
The Omega Speedmaster has been produced with two primary types of crystals: Hesalite and sapphire. Each possesses distinct characteristics that influence its suitability for different users and situations.
Omega Speedmaster Hesalite Crystal:
The original and arguably most iconic Speedmaster crystal is made of Hesalite, a type of acrylic plastic. This material has several advantages:
* Scratch Resistance (Relative): While not as scratch-resistant as sapphire, Hesalite is surprisingly durable and can withstand everyday wear and tear. Minor scratches can often be buffed out with a specialized polishing compound.
* Impact Resistance: Hesalite's significant advantage lies in its superior impact resistance compared to sapphire. This is crucial for a watch designed for demanding conditions. A dropped Hesalite crystal is far less likely to shatter than a sapphire crystal.
* Authenticity: For many collectors, the Hesalite crystal is an essential part of the Speedmaster's historical authenticity. The slightly yellowish tint that develops over time is considered by some to be a desirable characteristic, adding to the watch's unique character.
* Repair & Replacement: Hesalite crystals are generally less expensive to replace than sapphire crystals. The repair process is also often simpler and less demanding, although expertise is still required.
Omega Speedmaster Sapphire Crystal:
Some Speedmaster models, especially modern iterations, feature sapphire crystals. Sapphire is a synthetic crystalline material known for its exceptional properties:
* Scratch Resistance: Sapphire crystals offer significantly superior scratch resistance compared to Hesalite. This makes them ideal for individuals who value a pristine appearance and are concerned about daily wear.
* Clarity: Sapphire crystals generally offer better clarity and transparency than Hesalite.
* Durability: While less impact-resistant than Hesalite, sapphire is still highly durable and can withstand considerable force. However, a significant impact can still result in breakage.
* Cost: Sapphire crystals are generally more expensive to purchase and replace than Hesalite crystals. The replacement process can also be slightly more involved.
Speedmaster Professional Crystal Replacement (Hesalite & Sapphire):
The Speedmaster Professional, the iconic Moonwatch, presents a unique challenge for crystal replacement due to its design. The crystal is secured within the case by a bezel and requires specialized tools and expertise to remove and replace. Attempting a DIY replacement is strongly discouraged, as improper techniques can damage the watch case, bezel, or movement.
Omega Speedmaster Hesalite Crystal Replacement:
Replacing a Hesalite crystal on a Speedmaster, whether Professional or otherwise, requires a precise procedure. A skilled watchmaker will utilize specialized tools to carefully remove the old crystal, ensuring no damage to the surrounding components. The new crystal is then carefully fitted and secured, ensuring a proper seal to maintain water resistance.
Speedmaster Hesalite Replacement:
The term "Speedmaster Hesalite replacement" often encompasses the entire process of replacing the Hesalite crystal, including the removal of the old crystal and the installation of the new one. It's crucial to note that only genuine Omega parts or high-quality replacements from reputable suppliers should be used to guarantee proper fit and functionality.
