We specialize in watch battery replacement for Seiko Perpetual Calendar watches. Service prices start at $59 and include shipping.

If your Perpetual Calendar battery is replaced without the calendar being re-programmed, the date will not change. We can replace the battery correctly and re-program the calendar.

A Seiko Perpetual Calendar with an improperly installed battery will click in 5 second increments. We can install the battery properly and re-program the watch so it will tick in one second increments.

We will use the existing battery if we can, and you will receive a credit for the part. However, the battery cannot be reused if the setting sticker has been removed, altered or damaged.

Perpetual Calendar watches use an expensive, but long lasting lithium battery, and they require re-programming after the battery is installed to ensure the perpetual calandar functions continue to work properly.
