Heimdallr | Men’s Mechanical Watch Shanghai 7120 Manual Mechanical Movement 36Mm Retro Chinese Watch Suitable for Men’s Gifts

1Movement Model: Shanghai 8120 manual mechanical movement, with a battery life of about 40 hours.2There is a protective film on the mirror, so it is not a scratch on the mirror. Please tear it off if you mind.3: The movement is manual, requiring manual winding. Before purchasing, Google “the difference between manual and automatic movements” to confirm whether you truly need it.Please note the following: 1. If you purchase this watch, the strap size you will receive is 18mm. If this is a concern for you, please do not purchase it to avoid any disappointment. 2. If you plan to purchase a different strap for replacement, I recommend choosing a 19mm size. While the case is indeed better suited for 19mm, rubber straps in this size are rarely available on the market, which is why we have adapted to 18mm.
