Hey Guys! In this video – which, unfortunately, I can't actually *show* you in this text-based article – we're diving deep into the heart of a Rolex Submariner to replace a worn-out mainspring. The watch in question is approximately 12 years old and has seen its fair share of adventures, having undergone previous servicing. This article will detail the process, focusing on the specifics of a mainspring replacement in a Rolex Submariner, touching upon relevant aspects like Rolex mainspring screw size, sourcing Rolex replacement parts, and the nuances of working with vintage Rolex watch replacement parts, specifically those pertinent to the Rolex 2135 movement.
Understanding the Mainspring's Role:
Before we delve into the intricacies of the replacement, let's understand the critical role the mainspring plays. The mainspring is the powerhouse of a mechanical watch. This tightly coiled spring, housed within the watch's barrel, stores the energy that drives the entire mechanism. When fully wound, the mainspring exerts a constant force, which is regulated and released through the gear train, ultimately powering the hands and the complications of the watch. Over time, and through consistent use, the mainspring weakens and loses its ability to store and release energy efficiently. This manifests in several ways: reduced power reserve (the watch stops before its usual time), inconsistent timekeeping, and ultimately, a complete failure to function. Replacing a worn mainspring is therefore crucial for maintaining the accuracy and longevity of your Rolex Submariner.
Identifying a Worn Mainspring:
Several signs indicate a worn mainspring. As mentioned, a significantly reduced power reserve is a primary indicator. Instead of its usual power reserve of approximately 48 hours (this can vary depending on the specific movement), the watch might stop after only a few hours. You might also notice inconsistencies in timekeeping – the watch might gain or lose significant amounts of time, or even stop intermittently. A visual inspection during servicing might reveal a weakened or broken mainspring. Often, a mainspring will show signs of fatigue, such as kinks, bends, or a noticeably thinner section.
The Rolex Submariner and its Movements:
The Rolex Submariner has been produced across several generations, each featuring different movements. This article focuses primarily on the Rolex 2135 movement, a highly reliable and robust automatic movement commonly found in Submariners. However, the basic principles of mainspring replacement remain largely consistent across different Rolex movements. It is crucial to identify the specific movement within your Submariner before attempting any repair, as the parts are not interchangeable between different calibers. The case back typically has engravings indicating the model and movement number.
