Always been attracted by the sea and passionate about marine life, Anthony is a naturalist underwater photographer based in Marseille in the south of France. Graduated with a degree in marine biology, he created his blog (www.zesea.com) in 2008, where he relates his diving and travel adventures, teaches about the marine species he meets, and gives precious advice on underwater photography techniques. For the last ten years, he has been organizing live diving events abroad (Red Sea, Maldives, Philippines, ect,) on the theme of marine biology. He gives seminars in order to help divers better understand the environment in which...

Born in Paris (France), Steven was raised in Egypt in a diving center owned by his family. A dive instructor at 18 years old, he travelled across the world for over a decade. His trips and thousands of dives with sharks, led him to study not only shark behavior but also the threats affecting these species and their conservation. Founder of Shark Education in 2011, he specializes in shark-diver interactions and organizes thematic dive trips to discover sharks around the world as well as lectures and seminars during private and public events. He works in partnership with worldwide shark scientists...

Mechanical timepieces and self-winding or automatic watches have movements engineered to stay functional at all times. As part of their maintenance, the practice of watch winding is necessary to keep the timepieces running. Most watch enthusiasts believe that the watch's regular winding can maintain the rotor’s dynamic state, preventing it from an unexpected halt. The traditional mechanical watches need a manual winding while self-winding or automatic watches may need occasional winding.   What is watch winding? Winding is the process to power a mechanical watch's movement manually. The same concept applies to an automatic watch that stops working because the...

Aside from the rotating bezel, another distinct part of a dive watch is its dial with luminous hands and indexes. This characteristic helps divers navigate underwater easily. Due to its luminescent property, divers maintain better visibility even in the dark environments, preventing them from any imminent dangers that may arise while submerged in the water. While luminous dials are standard in dive watches, there are also casual timepieces with the same property. It is one reason why glowing dials have been an ongoing subject between watch collectors. It has interesting facts that are uncommon to most watch wearers. It is...

Wristwatches’ primary usage is for time-telling, especially the casual watches. However, the emergence of functional timepieces coined the term ‘tool watches’ over time, which referred to watches used as tools in accomplishing tasks. Today, among the known tool watches are the dive and pilot watches. The History of Tool Watches The term ‘tool watches’ became a buzzword around the early twentieth century, although its concept could be traced centuries ago. It was inspired by Queen Elizabeth I of England when she was given a watch on armlet by Robert Dudley in 1571. Another royalty, Queen of Naples, Caroline Murat, received a...

As a functional timepiece, a dive watch is prominent because of its rotating bezel. Perhaps, it is one of the main distinctive parts that set a diving timepiece apart from other watches. Although not all divers use a dive watch, it is essential to learn how the bezel works. In a dive watch, the bezel can either be an external or internal one. However, the most common is the external bezel, while a few brands have internal bezels. Most external bezels are unidirectional, although some are designed to move in both directions. For Aquinus, the rotating bezel is unidirectional and...
