Tissot PRX Automatic Watch - Gold - 40mm

An automatic (or self-winding) watch is a mechanical timepiece powered by the motion of the wearer's wrist. It does not require a battery; instead, an internal rotor winds the mainspring with kinetic energy. If not worn, it will eventually stop running after its power reserve is depleted.

The 80-hour power reserve means that once fully wound, your watch can continue to run accurately for approximately 80 hours (over three days) when not being worn.

The product description does not specify a water resistance rating. It is generally safe to assume that a watch without a stated water resistance is splash-resistant only. Avoid showering, swimming, or submerging your watch in water to prevent damage.

The Powermatic 80 movement is known for its reliability and precision. While not a certified chronometer, it typically performs within +/- 5 to 10 seconds per day under normal wearing conditions, often better than many standard mechanical movements, partly due to the Nivachron hairspring.

The Tissot PRX features an integrated bracelet design, meaning the bracelet is specifically designed to fit seamlessly with the unique case shape. While some aftermarket options exist, changing the bracelet typically requires specific tools and knowledge, and may alter the original aesthetic. Consult with an authorized dealer for options.

Nivachron is an innovative, non-magnetic alloy used for the balance spring (hairspring) in mechanical movements. It provides enhanced resistance to magnetic fields, temperature variations, and shocks, which contributes to greater accuracy and stability of the watch's timekeeping.

Your Tissot PRX is an automatic watch. If it has stopped, it likely needs to be wound. Either wear it consistently for several hours, or manually wind it by turning the crown in the first position clockwise about 20-30 times to build up the power reserve.

Minor inaccuracies can occur. Ensure the watch has sufficient power reserve (wear it daily). If the watch is consistently gaining or losing significant time, it may have been exposed to a magnetic field or require professional adjustment/servicing. Consult a certified watchmaker.

This indicates moisture has entered the watch case. Immediately take the watch to a professional watchmaker. Do not try to dry it yourself, as internal components can be damaged.

The integrated stainless steel bracelet requires special tools for adjustment. Take your watch to a Tissot authorized dealer or a professional watchmaker to have links added or removed for optimal fit.
