The Omega Speedmaster Professional Moonwatch. A name synonymous with space exploration, legendary status, and horological excellence. But within the hallowed halls of this iconic timepiece lies a crucial choice for the discerning collector: the crystal. Specifically, the choice between the sapphire crystal and the historically significant Hesalite crystal. Both versions offer the coveted "sandwich" dial construction, a hallmark of the Speedmaster's design, but subtle yet significant differences exist between the Omega Speedmaster Professional Sapphire Sandwich and its Hesalite counterpart. This article delves deep into these differences, exploring the nuances of each version and helping you decide which Speedmaster best suits your needs and preferences.
Height: A Matter of Millimeters
One of the most immediately noticeable differences between the sapphire and Hesalite versions lies in their height. The sapphire crystal Speedmaster sits noticeably taller on the wrist. This is a direct consequence of the material properties. Sapphire, while incredibly scratch-resistant, is a much denser material than Hesalite (acrylic). To achieve the required dome shape and strength, a thicker sapphire crystal is necessary, leading to the increased case height. This difference, while seemingly minor, can impact the feel and wearability of the watch, particularly for those with smaller wrists. The increased height of the sapphire model might feel more substantial and present, while the Hesalite version offers a more streamlined and comfortable profile. This is a purely subjective preference, and the best way to determine which height is preferable is to try both watches on your wrist.
The Applied Logo: A Nod to History
A key distinction, and a point of significant debate among collectors, is the presence of the applied Omega logo on the sapphire sandwich dial. This detail is a direct homage to the pre-moon Speedmasters, a period when applied logos were a common feature. The meticulous recreation of this detail adds a layer of historical authenticity and a touch of old-world charm to the sapphire version. The Hesalite version, however, forgoes the applied logo, opting instead for a printed logo.
The reasons for this omission on the Hesalite model are multifaceted. Firstly, the manufacturing process for applied logos is more complex and potentially more expensive. Secondly, the thinner profile of the Hesalite crystal may not provide sufficient depth for a cleanly applied logo without compromising the overall aesthetic. Finally, Omega may have opted to maintain a clear distinction between the historical aesthetic of the pre-moon Speedmasters and the modern interpretations embodied by the current Hesalite and sapphire models. Whether the absence of the applied logo is a drawback is entirely a matter of personal preference. Some collectors find the applied logo a crucial element of historical accuracy, while others see the printed logo as a modern and equally acceptable alternative.
Beyond the Crystal: Exploring the Movement and Variations
While the crystal and logo are significant visual differentiators, it's important to consider the broader context of the Speedmaster Professional. Both the sapphire and Hesalite versions are available with various movement options, adding another layer of complexity to the decision-making process.
Omega Speedmaster Moonwatch Sapphire: This category encompasses several variations, all sharing the sapphire crystal and the aforementioned applied logo. These models often feature the caliber 3861, a highly accurate and reliable movement directly descended from the legendary caliber 861. The Omega Speedmaster 3861 Sapphire, in particular, is a popular choice among enthusiasts, boasting improved performance and features compared to its predecessors. The price point for these sapphire models generally sits at the higher end of the Speedmaster spectrum.
