The Omega Speedmaster Professional, a watch synonymous with lunar exploration and enduring horological excellence, boasts a rich history of variations and complications. While the tachymeter bezel is perhaps its most iconic feature, the less common pulsometer bezel, and specifically its manifestation on the Speedmaster ref. 105.003-65, represents a fascinating chapter in the watch's story, one often overlooked by collectors. This article will delve into the intricacies of the Omega Speedmaster pulsometer bezel, exploring its function, its appearance on various Speedmaster models, and its place within the broader context of Omega's Speedmaster legacy.
Omega Speedmaster Pulsometer Bezel: Measuring Heartbeats
Unlike the tachymeter, which measures speed over a known distance, the pulsometer bezel is designed for measuring heart rate. Its graduated scale allows the user to determine the number of heartbeats per minute by timing a set number of beats (usually 30) and reading the corresponding value on the bezel against the second hand. This functionality, while perhaps less frequently used in modern life than speed measurement, made the pulsometer a valuable tool in medical applications during the watch's era of production. The pulsometer bezel, therefore, represents a unique blend of functionality and historical significance, adding another layer of intrigue to the already captivating Speedmaster lineage. The presence of a pulsometer bezel on a Speedmaster, especially the earlier models, is a testament to the versatility and adaptability of this legendary timepiece. It showcases Omega's willingness to experiment and cater to diverse needs, going beyond the purely sporting applications that the tachymeter initially suggested.

The combination of historical significance and rarity makes the 105.003-65 with a pulsometer bezel a true grail watch for many enthusiasts.
Omega Speedmaster Bezel: A Spectrum of Functionality
The Omega Speedmaster bezel is not limited to tachymeter and pulsometer scales. Throughout its production history, the Speedmaster has featured a variety of bezels, each with its own unique functionality and aesthetic appeal. As mentioned, some Speedmaster bezels incorporate telemeter scales, allowing the user to measure the distance to an event by observing the time elapsed between seeing the event and hearing its sound. These telemeter scales often incorporate both miles and kilometers for broader usability. The diversity of bezel scales employed on the Speedmaster underscores the versatility of the watch and its adaptability to different applications. This adaptability speaks to the enduring design of the Speedmaster, which has been successfully modified and adapted to incorporate various features without sacrificing its core identity. The variations in bezel functionality demonstrate Omega's commitment to innovation and the continuous improvement of its flagship timepiece.
