A great find in stainless steel and automatic movement, itâs the last one to disappoint its wearer. With a minimum life of 15 years, itâs Seikoâs in-house movement making this quality time piece, second only to much higher priced Swiss mechanical luxuries. It has the same beats per minute as many of its other expensive competitors but they donât have Seikoâs durability. In one word â itâs unbeatable.
