Based on the serial number, this watch was produced around 1991. The bracelet currently fits a wrist of approximately 18.5 cm, and two additional original bracelet links are included, allowing for further adjustment. The set includes the original international warranty card bearing a Japanese authorized retailer stamp and the sale date of December 7, 1994. Please note that the reference number and serial number fields on the warranty card are left blank, which was not uncommon for Japanese-issued cards of this period. The watch has undergone a complete overhaul by a Japanese professional watchmaker on February 1, 2026. The movement is running well with stable accuracy, and all chronograph functions operate correctly. The stainless steel case and bracelet show light signs of careful use consistent with age. The crystal is clear, and the dial and hands are well preserved. Included in the set are the outer box, inner box, international warranty card, swing tag, original booklets, and two additional bracelet links. Overall, this is a well-maintained and highly complete example with an attractive ownership history. Please review my seller rating and purchase with confidence
