Seiko Prospex Baby Tuna - high-quality and durable timepieces designed for various outdoor activities, including diving.
The name "Baby Tuna" comes from its resemblance to its larger counterpart, the "Tuna Marinemaster" series, which is known for its robust and durable design, originally developed for professional divers. The Baby Tuna watches are more compact and lightweight compared to the Marinemaster Professional Tuna models, making them suitable for daily wear while retaining the functionality and design elements of a serious diver's timepiece. These Baby Tuna are designed to withstand water pressure at significant depths, typically ranging from 200 meters (660 feet) to 300 meters (1,000 feet) depending on the specific model. Seiko uses durable materials such as stainless steel, Hardlex or sapphire crystals, and robust rubber or silicone straps to ensure the watches can endure challenging conditions.
