Setup, Compatibility & Care
Setting up the Tissot PR100 is straightforward. To adjust the time, gently pull the crown out to the furthest position and rotate it until the hands indicate the correct time, then push the crown back in. For care, keep the watch away from strong magnetic fields and extreme temperatures. While the watch is durable, it is recommended to have the water resistance checked by an authorized Tissot service center every time the battery is replaced to ensure the seals remain intact.
