History Introduced in the 1960s, the Seikomatic line was designed to showcase Seiko's advancements in automatic winding technology and reliable daily performance. Positioned just below the elite Grand and King Seiko lines, the Seikomatic models often featured high jewel counts, refined case designs, and premium details like the dolphin caseback motif, which denoted enhanced water resistance. The "R" designation in the Seikomatic-R series typically indicated a refined or revised iteration of the movement, offering a superb balance of luxury and practicality that remains highly appreciated by vintage enthusiasts today. / Second Vintage SKU: SEI-MDX-0002
