Mike S. February 7, 2023 My Spouse and I are earning our very first overseas trip right after around 28 years of relationship and they are headed to Switzerland in March. I have many Seiko automatics, a Magrette diver, a Seiko Turtle Exclusive version, a Seiko SPB169, and some others. https://www.watchesworld.com/understanding-the-complex-world-of-chronometers/
