This is a Swiss travel Alarm pocket watch with hinged back cover for standing on bedside table while traveling. This watch has a good plastic crystal, good luminous hour hand, minute hand and blued alarm hand. The watch has a good blued sub second hand. The watch has a metal case with friction and hinged covers. It does wind set and tick with brisk motion. The alarm is set from the back of the case. The alarm and movement are wound with the crown. This is a very nice clean, running vintage Swiss made travel pocket watch. The alarm works perfectly and has a nice loud sound.
