What does al mean on a watch?

The "AL" on a watch typically stands for "aluminum," indicating that the watch case or components are made from aluminum, a lightweight and corrosion-resistant material. This designation is often found in sports or casual watches, emphasizing durability and ease of wear. In some contexts, "AL" may also refer to "automatic" or "automatic winding," indicating that the watch is self-winding and doesn't require a battery.
