The Omega Speedmaster Professional Moonwatch, a legend in horological circles, is renowned for its robust design, impeccable reliability, and storied history. Its iconic caseback, typically engraved with the Speedmaster emblem and various inscriptions commemorating its lunar missions, is a significant part of its identity. However, the desire to see the intricate movement within this iconic watch has led many owners to explore aftermarket display backs. This article delves into the world of Omega Speedmaster display backs, specifically focusing on the feasibility and implications of replacing the solid caseback of older Speedmasters with aftermarket alternatives, particularly those offered by German manufacturers. We'll examine the various models, the potential benefits and drawbacks, and the crucial considerations before undertaking such a modification.
The allure of a display back is undeniable. For watch enthusiasts, the ability to visually appreciate the meticulously crafted movement, the rhythmic dance of the balance wheel, and the intricate interplay of gears is a compelling proposition. This is especially true for the Omega Speedmaster, whose caliber 1861 (in older models) and caliber 3861 (in newer models) are significant mechanical achievements in their own right. The question, therefore, isn't simply *why* someone might want a display back on their Omega Speedmaster, but rather *how* to achieve it safely and effectively without compromising the watch's integrity or value.
The Omega Speedmaster Professional Moonwatch, with its various iterations and movements, presents a unique challenge. While Omega itself offers models with sapphire crystal display backs, particularly with the caliber 3861, many owners possess older Speedmasters with solid casebacks. These older models, often cherished for their historical significance and potentially higher value due to their age and condition, are not easily converted to display backs using official Omega parts. This is where the aftermarket steps in.
Several companies, notably those based in Germany, have emerged as reputable manufacturers of aftermarket display backs specifically designed for the Omega Speedmaster. These aftermarket solutions often come with the necessary spacers and gaskets to ensure a proper fit and maintain the watch's water resistance. The quality of these aftermarket parts varies, so thorough research and due diligence are paramount. It's crucial to select a reputable supplier with a proven track record of producing high-quality, precision-engineered components. A poorly fitted or manufactured display back can lead to damage to the movement, water ingress, and a significant reduction in the watch's value.
Let's delve deeper into the specific models and considerations:
Omega Speedmaster Pro Moonwatch & Caseback Modifications:
The Omega Speedmaster Professional Moonwatch, often referred to simply as the "Pro Moonwatch," is the most iconic model in the Speedmaster family. Its solid caseback, typically featuring the iconic Seahorse medallion and various inscriptions, is a defining characteristic. Replacing this with a display back requires careful consideration. The process involves removing the original caseback, installing the aftermarket display back with appropriate spacers to maintain the correct movement height, and ensuring a water-resistant seal with a new gasket. Improper installation can damage the movement, compromise water resistance, and even scratch the crystal.
