This recommendation of ours proudly wears the name of ‘Big Tuna’ on the basis we are about to cover. The Marinemaster is truly a one in a million type of watch that many tend to put on their Christmas wishing list. The massive 48mm case features a shroud that adds the mandatory protection needed when diving – be sure it will last you at least a few decades. It is anti-magnetic, has a 300-meter water-resistance rate (not common for Seiko watches), and has a battery life that reaches 5 years. How mindboggling is that? You definitely get your money worth when investing in a piece like this.
With a rubber strap that fits snug on your wrist, you can conquer the underwater world in no time.
