The Omega Seamaster is not just a timepiece, it’s a legacy of precision, durability, and performance.
Whether you dive, swim, or simply wear it every day, keeping its battery fresh and ensuring its water resistance are essential to maintaining its functionality and value.
In Atlanta, several reliable options will service your Seamaster with the care it deserves.
Unlike standard watches, the Seamaster is built with advanced engineering that supports extreme conditions, often featuring helium escape valves, high-depth ratings, and chronometer-certified movements.
These features are designed for serious water exposure, but even the best craftsmanship needs proper upkeep.
A worn gasket or depleted battery can quickly compromise your watch’s performance or even lead to water damage.
Many Atlanta watch owners wonder if it’s really necessary to go to a specialist for something as small as a battery change.
The truth is, for high-end dive watches like the Seamaster, every maintenance decision matters.
This article explains what to expect when replacing the battery and performing a pressure test, how to choose the right service center, plus tips to extend its lifespan.
Why Battery Replacement Isn’t Just a Quick Fix
Seamaster models with quartz movements generally have a battery life of 2 to 4 years, depending on usage and environmental factors.
When the battery weakens, you might see the second hand jump in larger increments or stop altogether.
Replacing the battery involves more than popping the back open. A professional will:
- Use the right battery type, ensuring compatibility and quality
- Inspect and likely replace gaskets or seals to maintain water tightness
- Re-seal the case properly so that the case back and crown are secure
Improper battery replacement can lead to moisture ingress, damage to the movement, or loss of water resistance. Learn more about common watch problems and how professionals fix them.
What Makes the Seamaster Unique: Why Pressure Testing Matters
The Seamaster is designed for aquatic environments. Many versions are rated for 300 meters or more, making them true dive watches.
To maintain that kind of performance, a pressure test is crucial after any opening of the case.
A pressure test assesses whether the seals (gaskets), crown, case back, and crystal are tightly sealed against water and air under pressure.
There are two main kinds of pressure / water resistance testing: dry/air test and wet test. The first uses changes in air pressure to detect case expansion.
The second submerges the watch in water under pressure, looking for air bubbles or condensation.
Pressure testing confirms that after battery replacement, nothing is compromised.
Without it, even a good replacement job could fail under water. Take a closer look at what can go wrong with water damage and watches.
Omega Seamaster Battery Replacement and Pressure Test Process
Here’s what you should expect when you take your Seamaster to a professional service center in Atlanta:
The technician will open the case, remove the old battery, examine internal components, and replace any worn-out seals or gaskets.
They’ll fit a fresh, correct battery and ensure the compartment and contacts are clean.
After reassembling the case, they perform a dry test or air test to check for leaks, then a wet pressure test to match the Seamaster’s water resistance rating.
Some may even run a condensation test to verify internal dryness. Finally, accuracy, alignment, and function are inspected before the watch is returned to you.
Turnaround times can vary. Some local Atlanta shops may complete the service in a day or two, while authorized centers might take up to a week depending on their workload and parts availability.
For those located northeast of the city, watch battery replacement services in Johns Creek offer another convenient and reliable option.
Finding the Right Service Center in Atlanta
Atlanta is home to a range of skilled watchmakers, but not all service centers are equipped or qualified to handle the specific needs of an Omega Seamaster. When evaluating your options, consider the following:
First, look for a watch repair shop that has specialized experience with luxury watches, particularly Swiss brands like Omega.
Not all technicians understand the construction intricacies of dive watches, which makes a significant difference when it comes to tasks like pressure testing or resealing.
Second, verify whether the shop offers wet and dry pressure testing in-house.
Shops without proper testing equipment may still replace the battery, but they’ll often skip the pressure test entirely or send the watch off-site, increasing risk and turnaround time.
Some may even say it’s not necessary, this is a red flag for any watch with serious water resistance capabilities.
Next, check whether the service center uses genuine Omega parts. This includes batteries, seals, and gaskets.
Using aftermarket parts can void warranties, compromise water resistance, or lead to future complications.
Warranties and service guarantees are also important. A reputable shop will stand behind its work.
Whether it’s a 6-month or 12-month warranty on pressure testing and battery installation, having that backup ensures peace of mind.
Finally, take a look at online reviews and testimonials. What do other Seamaster owners say? Are turnaround times reasonable?
Are staff knowledgeable and responsive to questions? Locations like It’s About Time Inc. in Johns Creek are highly regarded for their expertise with Omega and other luxury brands.
They also offer luxury watch repair in Atlanta and have specialized pressure testing equipment.

Frequently Asked Questions
What is the typical lifespan of a battery in an Omega Seamaster?
For Seamaster models with quartz movements, expect the battery to last about 2 to 4 years, depending on how often the watch is used, exposure to harsh conditions, temperature variations, and whether there is regular maintenance. For more on timelines, check out how often an Omega should be serviced.
Will pressure testing always be included when replacing the battery?
Not always. Battery replacement and pressure testing are separate services. Some shops bundle them, but others charge extra for the test. Always ask in advance whether pressure testing is included. If it isn’t, insist on it, particularly if you wear your watch in water.
How often should I have my Seamaster pressure tested?
If you frequently swim, dive, or expose it to water, pressure testing once a year is a good idea. For more casual use, every 2–3 years or whenever you notice a drop in performance or suspect the seals may be compromised.
What happens if my Seamaster fails the pressure test?
If it fails, the water seals or gaskets are likely compromised; sometimes the case back or crown isn’t sealing properly. The service center should identify the failure point, replace or repair the offending component, then retest until no leaks are found. You should avoid using the watch in water until the problem is fixed.
Can I replace the battery myself to save money?
It’s possible, but risky. Unless you have the right tools, parts, and clean environment, you may damage the movement, misalign parts, or fail to reseal the watch properly. Incorrect resealing can lead to water damage which is far more expensive to fix. For peace of mind, rely on professional watch repair services in Atlanta.

Your Omega Seamaster is designed to be tough, reliable under pressure, literally, but it still requires careful upkeep.
The battery and pressure testing process, when done professionally, supports the features that make this watch iconic: accuracy, longevity, and water resistance.
