This is a 1960s automatic Seamaster watch, purchased 13 years ago from an antique watch shop in Tokyo. While the exact year isn't known, the salesperson at the time identified it as a 1960s model. I've used it extensively for work over the years, and have had it overhauled four times, every two years, taking great care of it. Although it's an automatic watch, being an older model, I wound it manually about 30 times every day. I haven't used it for the past three years, but it appears to be running when I look at it. However, the second hand sometimes becomes irregular, causing the time to be inaccurate. Therefore, an overhaul is necessary. Case width: approximately 3.4cm (excluding the crown) Lug width: 1.8cm The case has scratches. It comes with an imported leather band, but it shows signs of wear and has damage on the inside. Please consider the band as a bonus. This is an old item. It is not as accurate as a radio-controlled watch. Please understand that this is a used item and purchase it with the assumption that an overhaul is required. Please refrain from purchasing if you are overly concerned about details or seek perfection. In such cases, I recommend purchasing a new watch.
