Important Notes
While the watch is water-resistant to 5ATM, it should not be used for swimming, snorkeling, hot baths, or saunas, as heat and prolonged water exposure can compromise its seals. To maintain the luminous function, expose the watch to natural or bright artificial light for 3–5 hours daily. The silicone strap is durable but may attract dust; regular cleaning with a damp cloth is recommended. Always refer to the included user manual for proper operation of the chronograph and other functions. The product includes a warranty—details can be accessed via the manufacturer’s support page. With over 570 customer reviews averaging 4.4 out of 5 stars, the TB8204 is recognized for its value and performance in the men’s watch category.
