What Battery Does the Timex Weekender Use?

This is the most important question! The Timex Weekender typically uses a small, coin-shaped battery. The most common type you’ll find is the Energizer 377 or the S.R.626SW. These are also sometimes referred to as a 1.55-volt silver-oxide battery.

Why these specific batteries? They are chosen for their long life, consistent voltage, and compact size, which fits perfectly inside the slim profile of the Weekender watch. You can usually find these batteries at most electronics stores, supermarkets, drugstores, or online retailers.

It’s always a good idea to double-check your watch’s manual if you still have it, or look for the battery number printed on the back of the old battery once you open the watch. This ensures you get the exact match.

Why Battery Choice Matters

Voltage: Using the correct voltage (usually 1.55V for this watch) ensures your watch runs at the right speed. Too low, and it might stop; too high, and you could damage delicate components.
Type: Silver-oxide batteries are standard for watches because they provide a steady power output over a long period.
Size: The “377” or “SR626SW” size is designed to fit snugly in the battery compartment without being too tight or too loose.

Tools You’ll Need for a Timex Weekender Battery Change

Changing the battery in your Timex Weekender is a simple DIY task, and you don’t need a lot of fancy tools. Here’s what will make the job easy and safe:

A Small Flathead Screwdriver: This is essential for gently prying open the watch case back. Make sure it’s small enough to fit into the notch or indentation on the case.
A New Battery: As we discussed, a 377 or SR626SW (1.55V silver-oxide) battery is your best bet.
Tweezers (Optional but Recommended): These are helpful for picking up the old battery and placing the new one precisely without touching it too much.
A Soft Cloth or Microfiber Towel: To protect your watch and your work surface.
A Magnifying Glass (Optional): If your eyesight isn’t what it used to be, or if the tiny print on the old battery is hard to read.

Having these items ready will ensure a smooth and successful battery replacement. It’s like having the right wrench for a car repair – it just makes things easier!

Step-by-Step Guide: Replacing Your Timex Weekender Battery

Let’s get your Timex Weekender ticking again! Follow these simple steps carefully.

Step 1: Prepare Your Workspace

Find a clean, well-lit area. Lay down your soft cloth or towel to avoid scratching your watch or the surface it’s on. This also helps keep tiny parts from rolling away.

Step 2: Locate the Case Back Notch

Turn your Timex Weekender over so the back is facing you. Look closely at the edge of the watch case back. You should see a small notch, indentation, or a small lip. This is where you’ll insert your screwdriver.

Step 3: Gently Pry Open the Case Back

Insert the tip of your small flathead screwdriver into the notch. Wiggle it gently to pry the case back up. You might hear a slight pop as it comes loose. Don’t force it; if it feels stuck, try moving the screwdriver slightly around the notch. The case back is usually held by friction or a thin seal.

Safety Tip: Be gentle! You don’t want to bend the case back or damage the watch casing.

Step 4: Remove the Old Battery

Once the case back is off, you’ll see the watch mechanism and the coin battery. The battery is usually held in place by a small metal clip or lever. You might need to use your screwdriver or tweezers to gently lift this clip or lever to release the battery. Sometimes, you can just tip the watch slightly, and the old battery will slide out. If it’s stuck, use your tweezers to carefully grip it and lift it out.

Important: Note the position of the old battery before you remove it, especially which side is facing up (usually the positive side with the “+” symbol).

Step 5: Insert the New Battery

Using your tweezers (or your fingers if careful), pick up your new 377/SR626SW battery. Make sure the positive side (the one with the “+” symbol) is facing upwards, just like the old battery was. Carefully place the new battery into its slot. You might need to gently press it down to ensure it’s seated correctly. Ensure the metal clip or lever secures it in place.

Step 6: Reattach the Case Back

Carefully align the case back with the watch casing. There might be a small groove or indentation on the case back and the watch that needs to line up. Gently press the case back down. You might be able to close it just by applying firm, even pressure with your thumbs. If it doesn’t close easily, try aligning it again and pressing around the edges.

If your watch has a rubber O-ring seal for water resistance, make sure it’s in place and not pinched between the case back and the watch body.

Step 7: Test Your Watch

Once the case back is securely on, set the correct time and date on your watch. Check if the second hand is moving. If it is, congratulations! You’ve successfully replaced your Timex Weekender battery.

If the watch doesn’t start, double-check that the battery is inserted correctly (positive side up) and that the case back is fully sealed. Sometimes, the battery might be dead on arrival (though rare), so if it still doesn’t work, you might need to try another battery.

Understanding Battery Types and Lifespan

The batteries used in watches like the Timex Weekender are usually made of silver-oxide. These are chosen over other types like alkaline or lithium for a few key reasons that are important for watch performance:

Silver-Oxide vs. Other Battery Types

Battery Type	Voltage Stability	Lifespan	Common Uses	Suitability for Watches
Silver-Oxide (e.g., 377, SR626SW)	Very High – consistent power output	1-3 years (or more, depending on usage)	Watches, small electronics	Excellent – provides stable power needed for accurate timekeeping.
Alkaline (e.g., LR44)	Medium – voltage drops as it depletes	6 months – 1.5 years	Remotes, toys, some small electronics	Fair – can cause watches to run slow as battery weakens.
Lithium (e.g., CR2032)	High – but typically higher voltage (3V)	5-10 years	Computer motherboards, key fobs, torches	Generally Not Suitable – Voltage is too high for most standard watches like the Weekender.

As you can see, silver-oxide batteries are the standard for a reason. Their stable voltage ensures that your watch’s internal quartz mechanism receives a consistent, accurate power supply, which is critical for precise timekeeping. Alkaline batteries can cause your watch to run slower as they start to lose power, while lithium batteries often have a voltage that’s too high for typical watch movements, potentially causing damage.

How to Maximize Battery Life

While the battery life of your Timex Weekender battery is generally good, typically lasting between one to three years, there are a few things that can affect it:

Temperature Extremes: Very hot or very cold conditions can shorten battery life. Try to keep your watch at room temperature when possible.
Frequent Adjustments: Constantly setting the time or date, especially if the watch crown is pulled out for long periods, can draw more power.
Features: While the Weekender is a fairly simple watch, any additional features (like a backlight, if present) will naturally consume more power.

For most users, the battery life is excellent, and you’ll likely forget about it until it’s time for a replacement.

Troubleshooting Common Issues

Even with a new battery, sometimes watches can act up. Here are a few common issues and how to tackle them:

Watch Stops Working After Battery Change

Check Battery Orientation: Did you install the new battery with the positive (+) side facing up? This is the most common mistake.
Battery Contact: Ensure the battery is making good contact with both the positive and negative terminals. Sometimes, a slight bend of the metal clip can help.
Dead New Battery: Although rare, a new battery can sometimes be faulty. Try a different brand or battery from a different pack.
Internal Damage: If none of the above works, there might be an issue with the watch’s internal movement. Consult a watch repair professional.

Watch Runs Too Fast or Too Slow

Battery Power: Even a new battery needs to be the correct type and voltage. An old or incorrect battery can affect accuracy. Double-check you’re using a 377/SR626SW.
Demagnetization: While less common for quartz watches, exposure to strong magnetic fields can sometimes affect watch movements. A watchmaker can demagnetize it.
Quartz Movement Issue: The quartz crystal inside the watch regulates time. If this is malfunctioning, the watch can be inaccurate. This usually requires professional servicing.

Case Back Won’t Close Properly

Obstruction: Make sure there are no stray hairs, dust, or part of the battery itself sticking out.
O-ring Seal: If your watch has a water-resistant gasket (usually a thin rubber ring), ensure it’s seated correctly in its groove and isn’t being pinched or twisted. This seal is crucial. You can get more information on watch water resistance from resources like the University of North Carolina.
Bent Case Back: If the case back itself is slightly bent, it won’t seal properly. Try to gently flatten it on a hard surface if you suspect this.

Most of these issues are quite rare for the Timex Weekender, which is built for reliability. Following the steps precisely usually solves any problems.

How to Care for Your Timex Weekender Overall

Beyond just changing the battery, a little overall care will keep your Timex Weekender looking and working great for years to come. Remember, it’s designed to be a durable, everyday watch.

Keeping It Clean

Over time, dirt and grime can build up, especially around the bezel and strap. A simple cleaning routine can make a big difference:

Case and Crystal: Use a soft, damp cloth to wipe down the watch case and the crystal (the glass). For stubborn marks, a tiny bit of mild soap can be used, but rinse and dry thoroughly. Avoid harsh chemicals.
Straps: If you have a fabric or nylon strap, these can often be removed and hand-washed with soap and water, then air-dried. Leather straps should be wiped with a damp cloth and conditioned occasionally.

Water Resistance Considerations

The Timex Weekender is often advertised with water resistance, usually around 30 meters (about 100 feet). What does this really mean? This rating means the watch can withstand splashes, rain, and brief immersion in water. However, it’s generally NOT suitable for:

Swimming
Showering (hot water and steam can degrade seals)
Diving or high-pressure water activities

The water resistance seals can degrade over time, especially with exposure to heat and chemicals. If you frequently expose your watch to water or are concerned about its water resistance, it’s a good idea to have the seals checked and replaced periodically by a professional watchmaker. You can find more details about water resistance standards from organizations like the International Organization for Standardization (ISO), which outlines standards like ISO 22810 for water resistance.

Avoiding Shocks and Magnets

While durable, delicate watch movements can be affected by strong impacts. Try to avoid dropping your watch or exposing it to significant physical shock. Similarly, strong magnetic fields (from speakers, magnets, or certain electronic devices) can temporarily affect a watch’s accuracy. If your watch starts behaving erratically, keeping it away from potential magnetic sources might help.
