The Summit Collection: A Strong First Step for New Brand Earthen

Earthen Company is one of the freshest names to enter the watch market, founded in Hong Kong in 2025 by a group of passionate collectors and enthusiasts. Co-founder Jonathan Chan, also a key figure behind The Horology Club, explains that the team approached this project as collectors first, not as traditional watchmakers.

The result is a debut that doesn’t chase trends but instead offers something unique, a series of ceramic, field- and pilot-inspired watches at an accessible price point. With the launch of the Summit Collection, it’s clear Earthen intends to make an impression from day one.

Altimeter

An altimeter is a device that measures altitude or elevation above sea level. It is commonly used in aviation, mountaineering, and other outdoor activities to help determine one's location and to aid in navigation.

An altimeter can work based on various principles, such as barometric pressure or GPS technology. A barometric altimeter measures altitude by measuring the atmospheric pressure, which decreases as the altitude increases. The device contains a small aneroid barometer that expands or contracts with changes in air pressure, which moves a needle on the display to indicate the current altitude.

Altimeters are commonly found in watches designed for outdoor activities, as well as in dedicated handheld devices used by hikers, climbers, and pilots. They often include additional features, such as temperature readings and weather forecasting.

Mechanical wristwatches with altimeter features are relatively rare, as most altimeter watches use electronic sensors to measure altitude.
