The Omega Speedmaster Professional, affectionately nicknamed the "Moonwatch," is more than just a timepiece; it's a legend. Its iconic status, cemented by its role in NASA's Apollo missions, makes it a highly sought-after chronograph. But beyond its historical significance lies a sophisticated mechanism requiring understanding to fully utilize its capabilities. This article delves into the intricacies of operating the Omega Speedmaster chronograph, focusing particularly on the tachymeter scale, a key feature often misunderstood. We'll also touch upon various Speedmaster models, pricing, and historical context.
Understanding the Omega Speedmaster: More Than Just a Pretty Face
Before we dive into the practicalities of using the chronograph, let's briefly explore what makes the Omega Speedmaster so special. Often referred to as the Omega Speedmaster Professional, or simply the Omega Speedmaster Moonwatch, it's a manual-wind chronograph known for its rugged durability and precise timekeeping. It's not just a watch; it's a piece of history, a testament to human ingenuity and exploration. The Speedmaster family boasts a wide array of models, each with its own unique features and price point, which we’ll explore later.
Omega Speedmaster Chronograph Review: A Legacy of Excellence
The Omega Speedmaster chronograph has earned its stellar reputation through decades of unwavering performance. Its robust construction, featuring a sapphire crystal, stainless steel case, and a highly reliable movement (typically a manually wound calibre 1861 or 321, or a more modern co-axial movement), ensures longevity and accuracy. Reviews consistently highlight its legibility, comfortable fit, and the satisfying tactile experience of using its pushers and crown. The iconic design, with its black dial, prominent sub-dials, and distinctive tachymeter bezel, remains timeless and instantly recognizable. While the price point is a significant investment, the quality and heritage justify the cost for many enthusiasts.
Mastering the Chronograph Function: A Step-by-Step Guide
The chronograph function allows you to measure elapsed time with precision. Here's how to use it on your Omega Speedmaster:
1. Starting the Chronograph: Press the top pusher (located at 2 o'clock) to start the chronograph. The central chronograph seconds hand will begin moving, recording elapsed time.
2. Stopping the Chronograph: Press the top pusher again to stop the chronograph. The central chronograph seconds hand will stop at the exact elapsed time.
3. Resetting the Chronograph: Press the bottom pusher (located at 4 o'clock) to return all chronograph hands to their zero positions. This resets the elapsed time measurement.
Deciphering the Tachymeter: Measuring Speed and Distance
The tachymeter bezel, a prominent feature on the Omega Speedmaster, is a crucial tool for measuring speed over a known distance or distance over a known time. It's often misunderstood, so let's break it down:
* Measuring Speed: To measure speed, start the chronograph when passing a fixed point (e.g., a kilometer marker). Stop the chronograph when passing the next fixed point, the same distance away. The position of the central chronograph seconds hand on the tachymeter scale indicates your average speed. For example, if the hand points to "60," your average speed is 60 units per hour (e.g., 60 km/h or 60 mph, depending on the unit of distance between your markers).
