The Omega Speedmaster Professional Moonwatch, a legendary timepiece celebrated for its robust design and pivotal role in space exploration, isn't immune to the occasional mechanical hiccup. One recurring issue reported by owners, and the focus of this article, is the failure of the lower pusher – the button responsible for starting and stopping the chronograph function. This article delves into the reasons behind this common problem, explores potential causes, examines repair options, and offers advice on preventative maintenance to ensure your Speedmaster's chronograph functionality remains impeccable.
Understanding the Omega Speedmaster Pusher Mechanism:
Before we delve into the specific problem of a failing lower pusher, let's briefly examine the mechanism itself. The Omega Speedmaster's chronograph pushers are not simple on/off switches. They are intricate components integrated into the watch's complex movement. Each pusher is connected to a column wheel, a sophisticated system of gears that orchestrates the precise sequencing of the chronograph's start, stop, and reset functions. The pushers themselves are typically made of stainless steel, carefully designed to withstand pressure and impact. However, their exposed position makes them vulnerable to wear and tear, and the intricate mechanism they operate is susceptible to dust, debris, and even the effects of aging.
The lower pusher, specifically, experiences considerable stress. It's responsible for stopping the chronograph, a function that often involves a degree of force, especially if the chronograph has been running for an extended period. This repeated pressure, over time, can lead to various issues, ranging from minor stiffness to complete failure. The upper pusher, while also important, tends to experience less wear due to its simpler function of initiating the chronograph.
Why the Lower Pusher Fails: A Statistical Look and Potential Causes
My colleague's experience, mirroring many others, highlights a statistical reality: the lower pusher on the Omega Speedmaster is not inherently more prone to failure than the upper pusher. While anecdotal evidence might suggest otherwise, statistically, either pusher can malfunction. The perception that the lower pusher fails more often likely stems from the greater force often applied to it during operation and the more complex function it performs within the chronograph mechanism.
Several factors contribute to the failure of a Speedmaster's lower pusher:
* Wear and Tear: Years of use inevitably lead to wear and tear on the pusher itself, the column wheel, and associated components. The repeated pushing and releasing of the button can cause friction, leading to the gradual degradation of the parts. This is particularly true for watches that are frequently used, especially for timing events that require frequent starts and stops of the chronograph.
* Dust and Debris: The exposed nature of the pushers makes them susceptible to accumulating dust, dirt, and other debris. This debris can interfere with the smooth operation of the mechanism, causing stiffness, sticking, and ultimately, failure. This is especially relevant in environments with significant dust or exposure to elements.
* Impact Damage: Even a seemingly minor impact can damage the delicate mechanism within the pusher system. A knock or accidental drop can misalign components or cause damage that manifests as pusher malfunction. This is a particularly important consideration for those who wear their Speedmaster during activities that carry a risk of impact.
* Lubrication Issues: The proper lubrication of the chronograph mechanism is crucial for smooth operation. Over time, the lubrication can degrade, leading to increased friction and wear. Insufficient lubrication or the use of inappropriate lubricants can exacerbate this issue.
