This is a HAMILTON Pulsomatic, which is automatic. The watch functions properly and has no issues, but setting the time is difficult, which is a characteristic of the Pulsomatic. While the minute hand can be set normally, the hour hand is difficult to adjust. It takes a little effort, but you can change the hour by advancing the minutes. The battery lasts for more than 10 days when charged with normal use. I have confirmed that it was running after being left unused for about a month. Also, both of the strap keepers are missing. There are fine scratches from use. It seems that not everything from the original purchase is included. It was purchased at a SWATCH store. Please check the photos. 【Design】 HAMILTON digital watches feature a simple yet sophisticated design.
