Common Battery Types Used in Fossil Watches

Fossil watches typically utilize button cell batteries, also known as coin batteries, which are compact and designed for long-lasting power in small devices. The exact battery type depends on the specific model and movement of the watch, but most Fossil watches use silver oxide batteries due to their stable voltage and reliable performance.

Some of the frequently used battery models in Fossil watches include:

  • SR626SW (377): One of the most common silver oxide batteries for analog Fossil watches.
  • SR920SW (370/371): Used in larger or multifunction Fossil watches requiring higher capacity.
  • CR2032: A lithium coin battery occasionally used in Fossil smartwatches or models with digital functions.
  • SR621SW (364): For smaller, thinner models requiring a smaller battery diameter.

Silver oxide batteries are preferred in traditional quartz watches because they maintain a consistent voltage output over their lifespan, which is critical for accurate timekeeping.

Battery Specifications and Characteristics

Understanding the specifications of the batteries used in Fossil watches can help in selecting the correct replacement and ensuring optimal watch performance. Key characteristics include:

  • Voltage: Most silver oxide watch batteries operate at 1.55 volts, which helps maintain precise movement.
  • Capacity: Measured in milliampere-hours (mAh), this indicates how long the battery will last before needing replacement.
  • Size: Diameter and height must match the watch’s battery compartment to ensure proper fit.
  • Chemical Composition: Silver oxide batteries provide stable voltage, while lithium batteries offer longer life but different voltage profiles.

Below is a comparison table of common Fossil watch batteries with their specifications:

I’m Arron and I’ve always liked pulling things apart just to understand how they work. Watches were a natural obsession. Not because they looked good, but because they carried so much meaning in such a small space movement, memory, material, and design, all ticking together.

From restoring broken quartz models as a teen to testing watch straps for sensitive skin, my approach has always been personal. Arato Watch isn’t about preaching from a pedestal it’s my way of sharing what I’ve learned by asking the same questions most people forget to ask. I believe watches should be understood, not just worn. That’s exactly what this site is here to help you do.
