The Breitling Aerospace, with its sleek design and sophisticated functionality, is a coveted timepiece for many. A key feature contributing to its appeal is the integrated UTC (Coordinated Universal Time) module, allowing for effortless tracking of a second time zone. However, like all quartz watches, the Aerospace's UTC module relies on a battery, and eventually, that battery needs replacing. This article delves into the intricacies of Breitling UTC module batteries, addressing common questions, providing guidance on replacement, and exploring related Breitling models and their power sources.
My own experience with replacing the battery in my Breitling Aerospace highlights a common challenge: finding the correct battery type. While I successfully used an Energizer 371 for the main watch movement, pinpointing the specific battery for the UTC module proved more elusive. This underscores the importance of understanding the nuances of Breitling's battery specifications and the potential variations between models.
Understanding the Breitling UTC Module
Before diving into battery specifics, let's briefly examine the function and complexity of the Breitling UTC module. The module itself is a miniature marvel of engineering, responsible for independently tracking a second time zone. This is displayed usually via a separate 24-hour hand, allowing for quick and intuitive reference to a different time zone. The module's internal circuitry manages the synchronization and display of this additional time, often requiring a separate power source from the main watch movement.
This separate power source is crucial to understanding the battery replacement process. Many assume the main battery handles everything. However, in Breitling models with a dedicated UTC module, the main battery powers the primary watch functions (hours, minutes, seconds, chronograph functions if present), while a smaller, secondary battery powers the UTC module specifically. This is why replacing the main battery might not resolve issues with the UTC function. The failure of the UTC module is often indicated by a stopped or malfunctioning 24-hour hand.
Identifying the Correct Breitling UTC Module Battery
The exact battery type for your Breitling UTC module depends heavily on the specific watch model and the year of manufacture. Breitling did not always use a standardized battery type across all models and years. Therefore, simply assuming a particular battery type will work is risky. Improper battery installation can damage the delicate circuitry of the module.
Where to Find the Battery Information:
* Breitling's Official Website: The most reliable source is Breitling's official website or contacting their customer service. They can provide the correct battery type based on your watch's serial number. This is the recommended approach, ensuring you use the correct battery and avoid any warranty complications.
* Your Breitling Authorized Dealer: Authorized dealers have access to the same information and can perform the battery replacement professionally. This is often the most convenient option, ensuring the job is done correctly and without risk to your watch.
* Watch Repair Specialists: Experienced watch repair specialists familiar with Breitling watches will have a good understanding of the various battery types used in their models.
* Watch Manuals: While less common, some older Breitling manuals might specify the battery type for the UTC module. Check your watch's documentation.
Common Battery Types Used in Breitling UTC Modules:
While a definitive list is impossible without knowing the specific model and year, some commonly encountered battery types in Breitling watches (including those with UTC modules) include:
* SR626SW: This is a common button cell battery frequently used in watches.
* SR927SW: Another common button cell battery with slightly larger dimensions.
