The Omega Speedmaster Professional, famously known as the Moonwatch, is a legendary timepiece with a rich history and enduring appeal. Its robust construction and iconic design have cemented its place in horological history, but even the most resilient watch can require maintenance and repairs over time. One common issue that Speedmaster owners encounter is the need for glass replacement, whether it's a cracked crystal, a scratched sapphire, or a damaged Hesalite. This article delves into the intricacies of Omega Speedmaster glass replacement, covering various aspects from choosing the right replacement to finding reliable repair services and understanding warranty implications.
Understanding Omega Speedmaster Glass Options:
The Omega Speedmaster Professional has historically been available with two types of crystals: Hesalite and Sapphire. Understanding the differences between these two materials is crucial when considering a replacement.
Omega Speedmaster Hesalite Crystal:
The original and iconic choice for the Speedmaster Professional, Hesalite is a type of acrylic plastic. Its advantages include:
* Superior scratch resistance compared to other plastics: While not as scratch-resistant as sapphire, Hesalite is surprisingly durable and can withstand everyday wear and tear.
* Easier to replace: Hesalite crystals are generally less expensive and easier to replace than sapphire crystals, making repairs more affordable and quicker.
* Unique appearance: The slight curvature and subtle texture of the Hesalite crystal contribute to the Speedmaster's distinctive aesthetic, adding to its vintage charm.
* Cracking behaviour: While resistant to scratching, Hesalite can crack under significant impact. This cracking often presents itself as a starburst pattern originating from the point of impact. This characteristic is often seen as part of the watch's history, reflecting its rugged use. However, a badly cracked Hesalite crystal will compromise the watch's water resistance and should be replaced.
* Yellowing with age: Over time, Hesalite can yellow due to exposure to UV light. This is a common characteristic of vintage Speedmasters and is considered by many collectors to add to the watch's patina. However, if significant yellowing is undesirable, replacement is an option.
Omega Speedmaster Sapphire Crystal:
A more modern alternative, sapphire crystals offer superior scratch resistance compared to Hesalite. Their advantages include:
* Exceptional scratch resistance: Sapphire is significantly harder than Hesalite and is highly resistant to scratches, preserving the clarity of the crystal for a longer period.
* Increased clarity: Sapphire crystals generally offer better clarity and transparency than Hesalite.
* Higher cost: Sapphire crystals are more expensive than Hesalite, both in terms of the material cost and the specialized tools and expertise required for installation.
* More difficult replacement: Due to their hardness and precision fitting, replacing a sapphire crystal requires more specialized tools and expertise. Improper installation can damage the watch case.
* More prone to shattering: While scratch-resistant, sapphire is more prone to shattering upon impact than Hesalite. The impact energy is not absorbed as readily as with Hesalite, resulting in a complete fracture rather than a crack.
Omega Speedmaster Replacement: Choosing the Right Crystal:
The choice between Hesalite and sapphire depends largely on individual preferences and priorities. Hesalite maintains the traditional feel of the Speedmaster and offers a more affordable and readily replaceable option. Sapphire, on the other hand, provides superior scratch resistance and clarity but comes at a higher cost and requires more specialized repair services. Consider the following:
