Adrian Barker is the founder of Bark & Jack, a popular platform in the watch enthusiast community. Initially launched as an Instagram account, Bark & Jack evolved into a YouTube channel, website, and e-commerce store, primarily focusing on watch reviews, lifestyle content, and high-quality NATO watch straps.

Barker's YouTube channel, known for its in-depth, personal reviews of both luxury and affordable watches, quickly gained a large following. Over time, his channel became the most-watched UK-based YouTube channel about watches. In 2022, Adrian rebranded the YouTube channel to his own name, reflecting a more personal take on the watch world without distancing himself from his successful Bark & Jack brand

On his website, Bark & Jack offers a range of premium watch accessories, particularly NATO watch straps, which have become highly popular among watch collectors. Known for their quality, these straps, including innovative blends like the Seventy30 range and ribbed nylon designs, are sold both online and through select retailers​.

Beyond YouTube and e-commerce, Barker co-hosts a podcast called About Effing Time, further expanding his presence in the horology world. While his content is predominantly focused on watches, Adrian also shares his love for coffee, photography and other lifestyle interests​
