What is the compatible battery for the Bulova Precisionist 98B317 watch and how do I replace it?

Question

Accepted Answer

The Bulova Precisionist 98B317 watch is equipped with a silver oxide battery type SR920 (equivalent to 371), which powers its high-frequency quartz movement operating at 262 kHz. This battery offers a lifespan of about one year with normal use.

According to the recommendations of the manufacturer Bulova, it is strongly advised to have the battery replaced by an authorized Bulova dealer or a professional watchmaker. This precaution is important to ensure the water resistance of your watch, which has a water resistance of 300 meters. Improper handling during replacement could damage the seals and compromise this protection.

If you wish to replace the battery yourself, here is the procedure to follow with caution. First, gather the necessary equipment: a small screwdriver (usually a fine blade or Phillips), a specialized watch case opener, anti-static tweezers or latex gloves, and an SR920 battery (Renata, Energizer, or equivalent quality). Use the case opener to gently remove the back of the case by sliding it into the groove provided for this purpose. Once the back is open, note the position of the old battery before removing it with the tweezers.

To insert the new battery, never touch it with bare fingers to avoid corrosion and other damage. Place the battery correctly by checking the polarity (the positive side + should generally be facing up, but consult the diagram inside the case). Once the new battery is in place, carefully close the back of the case, ensuring it is properly screwed or snapped shut according to the type of closure of your watch. Test the watch to ensure it is functioning correctly.

Important: never leave your watch unused with a depleted battery, as the risk of leakage can damage the movement. Additionally, if you store the watch for an extended period, leave the crown screwed in the "OUT" position to minimize battery consumption. If you have any doubts about the procedure or are not comfortable with this handling, a professional can perform the replacement quickly and at a generally moderate cost.
