Hesalite: Lightweight, vintage aesthetic, scratch-prone (but easily polishable). Sapphire: Superior scratch resistance, slightly heavier, lacks the “moonwatch” charm.
Introduction
The Omega Speedmaster is a legendary timepiece, forever linked to history as the watch worn by Buzz Aldrin on the moon landing. But within the Speedmaster family, a crucial decision awaits: Hesalite or Sapphire? Both versions boast iconic design and robust functionality, but the crystal choice significantly impacts aesthetics, durability, and even historical significance.
Let’s embark on a detailed exploration to help you choose the Speedmaster that perfectly aligns with your style and preferences.
Congratulations! You’ve set your sights on the Omega Speedmaster, a watch synonymous with adventure, precision, and timeless design. However, your journey doesn’t end there. The Speedmaster comes in two crystal options: Hesalite and Sapphire. Both offer exceptional clarity for viewing the watch face, but each caters to a distinct personality.
This guide will dissect the intricacies of these crystal materials, empowering you to make an informed decision and select the Speedmaster that reflects your unique style.
History
Understanding the history behind these crystals adds context to your choice.
- Hesalite (Acrylic): The original Speedmaster, worn by astronauts during the Apollo missions, featured a Hesalite crystal. This lightweight and affordable material offered a clear view of the dial and was considered adequate for space missions due to its shatter resistance. Additionally, the slight dome shape of the Hesalite crystal became a beloved design element, contributing to the watch’s iconic appearance.
- Sapphire: In recent years, Omega introduced Speedmaster models with a Sapphire crystal. This synthetic material boasts superior scratch resistance, a quality highly sought after in everyday wear. While not featured on the original moon landing Speedmasters, the Sapphire crystal offers a modern touch and enhanced durability for active lifestyles.
Technical Breakdown
Let’s delve deeper into the technical specifications of these crystals:
Material and Properties:
| Feature | Hesalite (Acrylic) | Sapphire |
|---|---|---|
| Material | Polymethyl methacrylate (PMMA) | Synthetic crystal (grown from aluminum oxide) |
| Durability | Scratch-prone, but easily polishable | Highly scratch-resistant |
| Weight | Lighter | Slightly heavier |
| Clarity | Excellent | Excellent |
| Shatter Resistance | More resistant to shattering than glass | Highly shatter-resistant |
| Cost | More affordable | More expensive |
Visual Characteristics:
| Feature | Hesalite (Acrylic) | Sapphire |
|---|---|---|
| Shape | Domed | Flat with a beveled edge (may have a slight dome on some models) |
| Optical Distortion | Slight distortion at extreme angles | Minimal to no distortion |
| “Milky Ring” | May develop a faint milky ring around the edges over time | No milky ring |
Practical Considerations:
The choice between Hesalite and Sapphire boils down to your priorities:
- Durability: If leading an active lifestyle or prone to bumps and scrapes, the superior scratch resistance of Sapphire offers peace of mind.
- Weight: The lighter weight of Hesalite might be preferable for all-day comfort, especially on larger wrists.
- Aesthetics: The domed Hesalite crystal is a cherished design element for those seeking the classic “moonwatch” look.
- Cost: Hesalite offers a slight cost advantage over Sapphire models.
Design and Aesthetics
Dial Design:
Both Hesalite and Sapphire Speedmasters feature the same iconic black dial with luminous hands and markers. The date window at the 3 o’clock position and tachymeter scale on the bezel are present on all models.
Case and Bracelet:
The Speedmaster comes in a variety of case materials, including stainless steel, titanium, and even precious metals like gold and platinum. The bracelet options typically include a stainless steel link bracelet or a sporty nylon strap (affectionately nicknamed the “Speedy strap”).
The crystal choice (Hesalite or Sapphire) doesn’t affect the case or bracelet options available.
Brand Image:
The Hesalite crystal is undeniably linked to the Speedmaster’s historical significance. For those seeking a timepiece that embodies the legacy of the moon landing, the Hesalite crystal is a clear choice. However, the Sapphire crystal doesn’t diminish the watch’s prestige and functionality. It caters to those who prioritize a modern aesthetic and enhanced durability.
User Feedback
Here’s a glimpse into what Speedmaster owners have to say about their crystal choices:
Hesalite Fans:
- Love the vintage aesthetic: Many users appreciate the domed Hesalite crystal for its classic charm and association with the original moon landing Speedmasters.
- Easy to polish scratches: Hesalite’s scratchability is often downplayed by enthusiasts who find minor scratches easily buffed out with Polywatch or similar acrylic polishes.
- Lightweight comfort: The lighter weight of Hesalite is a plus for some wearers, especially those with smaller wrists.
Sapphire Enthusiasts:
- Enhanced durability: For those leading active lifestyles, the scratch resistance of Sapphire provides peace of mind.
- Crisp, clear view: Sapphire offers a slightly sharper view of the dial due to its minimal distortion.
- Modern aesthetic: The flat or slightly domed Sapphire crystal caters to those who prefer a more contemporary look.
Ultimately, user feedback highlights that both Hesalite and Sapphire have passionate followings. The ideal choice depends on your individual priorities and how you plan to wear your Speedmaster.
VII. Common Problems
Hesalite:
- Scratches: As mentioned earlier, Hesalite is prone to scratches. While polishable, deep scratches can be permanent.
- “Milky Ring”: Over time, the Hesalite crystal may develop a faint milky ring around the edges, affecting aesthetics. This can be mitigated by professional polishing.
Sapphire:
- Internal Reflections: In rare cases, Sapphire crystals can exhibit internal reflections under certain lighting conditions. However, this is uncommon and shouldn’t significantly impact daily wear.
- Chipping: While highly scratch-resistant, Sapphire can chip if struck with significant force. Replacing a chipped Sapphire crystal is generally more expensive than polishing a scratched Hesalite one.
Both Hesalite and Sapphire offer exceptional durability for a timepiece. However, the specific challenges of each material are worth considering based on your lifestyle and risk tolerance.
The Final Lap: Choosing Your Champion
The Hesalite Champion:
- You prioritize the classic “moonwatch” aesthetic.
- Minor scratches don’t bother you, and you’re comfortable with occasional polishing.
- You appreciate the lighter weight for all-day comfort.
- Sticking to a tighter budget is a concern.
The Sapphire Champion:
- Leading an active lifestyle demands superior scratch resistance.
- You prefer a crisp, clear view of the dial with minimal distortion.
- A modern aesthetic is more appealing.
- Replacing a chipped Sapphire crystal isn’t a major concern.

FAQs
1. Can I upgrade the crystal on my Speedmaster?
Yes, replacing the crystal on your Speedmaster is possible. However, it’s crucial to have a certified Omega watchmaker perform the service to ensure proper installation and maintain the watch’s water resistance. Upgrading from Hesalite to Sapphire might be more expensive due to the higher cost of the Sapphire crystal itself.
2. Does the crystal affect the watch’s value?
Traditionally, Hesalite crystals have been associated with the vintage Speedmasters and might hold a slight premium for collectors seeking a historically accurate timepiece. However, Sapphire crystal Speedmasters are still highly sought after, and the overall value of your watch depends on various factors beyond the crystal material, such as the model, condition, and year of manufacture.
3. How can I tell if my Speedmaster crystal is Hesalite or Sapphire?
The easiest way is to consult your watch’s documentation. If you don’t have the manual, you can examine the crystal itself. Hesalite crystals typically have a slightly domed shape and might show a faint milky ring around the edges with age. Sapphire crystals are usually flat or slightly domed and will have a sharper, more transparent appearance.
4. Can I replace a scratched Hesalite crystal with a Sapphire crystal?
Technically, yes. However, it’s important to consider if this modification aligns with your goals. If you prioritize maintaining the historical character of your Hesalite Speedmaster, replacing it with a Sapphire crystal might detract from its original charm. On the other hand, if functionality and scratch resistance are your top priorities, upgrading to Sapphire might be a worthwhile
