Although the Tissot Seastar collection is based on water resistance, every Tissot watch is water resistant to a certain level. Check the specifications of the desired model to be sure of the level of water resistance and how much water pressure the watch can withstand. Since water resistance can also be affected by factors such as temperature changes, external influences, and natural wear of seals, we recommend consulting our sales advisors about the specific water resistance and maintenance instructions for your watch.
