There’s a quiet satisfaction in the ritual of watch maintenance—especially when it comes to a Nixon, a brand that blends rugged American craftsmanship with timeless design. Unlike digital watches that die with a single battery, Nixon’s mechanical movements demand a more deliberate approach. The process isn’t just about swapping a battery; it’s about respecting the engineering behind your timepiece, ensuring its longevity, and preserving its resale value. Skimp on the details, and you risk misalignment, water damage, or even voiding a warranty. Do it right, and you’ll extend the life of your watch by years, if not decades.
Most Nixon watch owners wait until the second hand stutters or the date skips a day before acting. By then, the battery—often a tiny silver oxide or lithium cell—may have corroded, leaving behind a residue that can seep into the movement. The key is intervention before the symptoms worsen. But where do you start? The tools required are minimal, yet the technique demands precision. A wrong move with a screwdriver can strip the caseback, and forcing a stubborn battery can crack the glass. This guide cuts through the guesswork, offering a step-by-step breakdown of how to change a battery in a Nixon watch without compromising its integrity.
Nixon watches, particularly the iconic Portofino and President models, are designed for durability, but their battery compartments vary. Some feature screw-down casebacks, others snap-on backs, and a few (like the Nixon Day-Date) require disassembly of the entire case. The first step is identifying your model’s specific architecture—because what works for a Military series might not apply to a Mariner. Ignore this distinction, and you risk damaging seals or misplacing delicate components. Below, we dissect the anatomy of a Nixon watch, the tools you’ll need, and the exact sequence to replace the battery while maintaining water resistance and accuracy.
The Complete Overview of Changing a Battery in a Nixon Watch
Replacing a battery in a Nixon watch is a task that separates the casual wearer from the connoisseur. It’s not merely about extending the life of your timepiece—it’s about understanding the interplay between its mechanical heart and the delicate electronics that keep it ticking. Nixon watches, particularly those from the 1970s through the 1990s, often use silver oxide batteries (like the SR626SW), which last roughly 18–24 months before degradation sets in. Modern Nixon models may employ lithium cells (e.g., CR1025), which can last up to five years but require stricter handling due to their volatile nature. The process begins with disassembly, but the real skill lies in reassembly: ensuring the caseback seals properly, the gasket remains intact, and the movement aligns perfectly with the crystal.
Before you begin, gather your tools: a watch caseback opener (or a precision screwdriver set for screw-down backs), tweezers with a fine tip, isopropyl alcohol (90% or higher), cotton swabs, and a magnifying glass. If your Nixon watch has a snap-on back, you’ll also need a plastic pry tool to avoid scratching the case. Proceed in a well-lit area with a soft, non-slip surface—preferably one that won’t scratch the watch if it slips. Time yourself: an experienced watchmaker can complete this in under 30 minutes, but your first attempt might take longer. Patience is critical; rushing leads to stripped screws, bent battery contacts, or even a damaged movement.
Historical Background and Evolution
The Nixon Watch Company, founded in 1917, has a legacy tied to innovation in watchmaking. By the 1970s, as quartz watches began dominating the market, Nixon adapted by introducing hybrid movements that combined mechanical precision with battery-powered accuracy. These early electronic-mechanical watches required battery replacements far more frequently than traditional mechanical timepieces, creating a niche for watchmakers who specialized in how to change a battery in a Nixon watch without damaging the delicate quartz circuits. The Nixon Day-Date, for instance, used a beta 21 movement that relied on a silver oxide battery—replacing it improperly could disrupt the date function entirely.
Today, Nixon watches span a spectrum from vintage collectibles to modern divers. The Portofino series, for example, often features a screw-down caseback with a gasket that must be seated perfectly to maintain water resistance. Older models, like the Nixon Military, may have snap-on backs that require careful leverage to avoid cracking the plastic or metal housing. The evolution of Nixon’s battery technology mirrors the broader watchmaking industry’s shift from mercury batteries (now banned) to lithium and silver oxide cells. Understanding your watch’s era is crucial: a 1980s Nixon might use a SR626SW, while a 2010s model could require a CR1025. Mixing these up can lead to corrosion or premature failure.
Core Mechanisms: How It Works
The battery in a Nixon watch serves as the power source for either a quartz movement (which uses vibrations to keep time) or a hybrid mechanical-quartz system (where the battery powers the date function or second hand). When the battery depletes, the watch’s accuracy suffers first—often manifesting as a slowing second hand or a date that skips days. Inside the caseback, the battery sits in a metal or plastic holder, connected to the movement via two contact points. These points can corrode over time, especially if the watch has been exposed to moisture. During replacement, these contacts must be cleaned with isopropyl alcohol and a cotton swab to ensure a strong connection.
The physical process of removal varies by model. For screw-down casebacks, you’ll use a precision screwdriver (often a #0 or #1) to loosen the screws in a star or cross pattern, preventing case warping. Once loose, the back lifts off, revealing the battery nestled against the movement. For snap-on backs, a plastic pry tool is inserted into the seam and gently pried open—never force it, as this can damage the gasket. Once the back is off, the battery is typically held in place by a small metal clip or spring. Use tweezers to lift it out, then inspect the contacts for corrosion. If the old battery has leaked, the entire movement may need cleaning with alcohol before inserting the new one.
Key Benefits and Crucial Impact
Knowing how to change a battery in a Nixon watch isn’t just about saving money on a jeweler’s visit—it’s about preserving the watch’s heritage and functionality. A properly replaced battery ensures the movement remains aligned, the water resistance isn’t compromised, and the watch retains its original accuracy. Many Nixon watches, especially vintage models, appreciate in value when well-maintained. A watch with a fresh battery, clean movement, and intact gasket is far more desirable to collectors than one with a sluggish second hand and corrosion stains. Additionally, regular battery replacements prevent the buildup of hydrogen gas (a byproduct of battery degradation), which can damage the movement’s internal components over time.
Beyond maintenance, this skill grants you autonomy over your timepiece’s lifespan. Watchmakers charge $50–$150 for a battery replacement, but the cost of tools (a caseback opener, tweezers, and alcohol) is a one-time investment. For enthusiasts who own multiple Nixon watches, the savings add up quickly. Moreover, attempting this process yourself—even if you later take it to a professional—helps you identify potential issues, like a faulty movement or water damage, before they worsen. The psychological satisfaction of opening, servicing, and closing your watch is unmatched, turning a routine task into a rite of passage for watch aficionados.

Comprehensive FAQs
Q: How often should I replace the battery in my Nixon watch?
A: Nixon watches with silver oxide batteries (common in vintage models) typically need replacement every 18–24 months. Lithium batteries (found in newer Nixon watches) last 3–5 years. If your watch’s second hand slows or the date function fails, it’s time for a replacement—don’t wait until the battery leaks, as corrosion can damage the movement.
Q: Can I use any battery type in my Nixon watch?
A: No. Always check your watch’s manual or the movement’s markings for the correct battery type. For example, a SR626SW (silver oxide) won’t work in a watch designed for a CR1025 (lithium). Using the wrong battery can cause corrosion, inaccurate timekeeping, or even movement failure. If you’re unsure, consult a watchmaker or Nixon’s customer service.
Q: What happens if I don’t replace the battery in time?
A: A dying battery can lead to hydrogen gas buildup, which corrodes the movement’s contacts and internal components. Over time, this causes inaccuracy, date skipping, or complete failure. In extreme cases, corrosion can spread to the crystal or caseback, requiring costly repairs. Regular replacements (every 2–3 years) prevent these issues.
Q: Do I need to take my Nixon watch to a professional for battery replacement?
A: Not necessarily. If you’re comfortable with precision work and have the right tools, you can do it yourself. However, if your watch has a complex movement (e.g., automatic-quartz hybrid) or signs of water damage, a professional is safer. For most basic Nixon models, DIY replacement is straightforward—but if you’re unsure, err on the side of caution.
Q: How do I know if my Nixon watch’s battery is leaking?
A: Look for white or greenish corrosion around the battery contacts or inside the caseback. A foul odor (similar to rotten eggs) is another sign. If you see crusty residue on the movement or battery holder, the battery has likely leaked. In this case, clean the movement with isopropyl alcohol before inserting a new battery, and consider professional servicing if corrosion is severe.
Q: Can I use a longer-lasting battery to extend the time between replacements?
A: Yes, but only if the battery is chemically compatible with your watch’s movement. For example, a CR1025 lithium battery (3V) can replace a SR626SW silver oxide (1.55V) in some Nixon models, but this may affect accuracy. Always verify compatibility first. Some watchmakers recommend alkaline batteries for temporary use, but these can leak and cause damage.
Q: What should I do if the caseback won’t unscrew?
A: If the screws are stripped or seized, never force it—this can crack the case. Instead, apply watch screw oil or WD-40 Specialist to the threads and let it sit for 10–15 minutes. Try loosening again gently. If that fails, take it to a professional, as brute force can ruin the case.
Q: Will replacing the battery affect my Nixon watch’s water resistance?
A: Only if the gasket is damaged or not reseated properly. Always ensure the gasket is clean, free of debris, and compressed evenly when reattaching the caseback. Test water resistance by submerging the watch in water (up to its rated depth) after reassembly—if bubbles form, the seal is compromised.
Q: Are there any risks of damaging the movement during battery replacement?
A: Yes, if you’re not careful. The movement is delicate, and static electricity, corrosion, or physical pressure can damage it. Always handle the movement by its edges, avoid touching the contacts, and use anti-static precautions (like grounding yourself) if working in a dry environment. If you’re unsure, disassemble only what’s necessary to access the battery.
Q: Can I reuse the old battery holder in my Nixon watch?
A: Generally, yes—but inspect it first. If the holder shows signs of corrosion, cracks, or bent contacts, replace it. A damaged holder can cause poor battery contact, leading to inaccurate timekeeping or premature battery drain. Some watchmakers recommend replacing the holder every few years as a preventive measure.
