IMPORTANT NOTICE: This watch is water-resistant and was pressure-tested prior to shipment at the rated specification at the time of assembly. Water resistance is not a permanent condition and may be affected by gasket wear, accidental impacts, improper handling, temperature changes, chemical exposure, chlorine, salt water, or failure to properly secure the crown. The customer is solely responsible for ensuring that the crown is fully secured before any contact with water. Because it is impossible to verify handling conditions after delivery, any damage caused by water intrusion, moisture, humidity, or condensation is strictly excluded from warranty coverage under all circumstances. No refunds, replacements, repairs, reimbursements, or chargebacks will be accepted for water-related damage. We specialize in crafting personalized timepieces tailored to individual client preferences. It's important to note that this particular watch is not manufactured by Seiko and we have no affiliation with, nor do we represent Seiko or any other watch brand.
