When I was on the hunt for a reliable, stylish automatic watch, the Seiko 5 21 Jewels Automatic with the green face quickly caught my attention. Here’s what I learned and considered during my buying journey, which might help you decide if this watch is right for you.
Understanding the Seiko 5 Series
I first wanted to know what makes the Seiko 5 series special. The “5” represents five key attributes: automatic movement, day-date display, water resistance, a recessed crown at 4 o’clock, and a durable case and bracelet. This combination has made the Seiko 5 a legendary and affordable choice for watch enthusiasts like me.
