This is a Swiss-made automatic watch, Libenham. I like automatic watches and have been collecting them. The automatic winding function works, and it can be used for a short time, but it seems the winding is weak, and it stops after a while. The same is true when manually winding it. You may want to consider purchasing it with the possibility of repair. Please purchase with the understanding that this is the current condition. No claims and no returns, please. A simple and sophisticated design automatic wristwatch. - Brand: Libenham - Model: PF-90032 - Material: Stainless steel - Band type: Mesh band - Dial color: Black - Water resistance: Waterproof - Automatic winding function: Yes Thank you for viewing.
