A “terra cielo mare” watch is a type of timepiece designed for use in three different environments: land, sky, and sea. These watches are typically robust and durable, with features that make them suitable for use in all conditions.
“Terra cielo mare” is Italian for “earth, sky, sea”. The term was first used to describe a type of watch developed by the Italian watchmaker Panerai in the 1930s. These watches were designed for use by the Royal Italian Navy and were known for their reliability and precision.
