Bulang and Sons is a destination for watch enthusiasts who value vintage craftsmanship, timeless design, and carefully selected collector pieces. The brand centres its work on a passion for vintage watches, offering authentic examples from makers such as Rolex, Tudor, Omega, Patek Philippe, Cartier, and Audemars Piguet. Each watch is assessed for originality, condition, and history, with authenticity and certification information, service and warranty guidance, and options to sell a watch to the company. Customers can browse online or arrange a private viewing at The Lounge in Maastricht, with remote appointments also available.

Alongside watches, Bulang and Sons offers its own range of leather straps and a broad selection of watch bands in materials including alligator and other exotic leathers, steel, nylon, rubber, and textile. Straps are organized by size, type, and compatible watch brand. The catalogue also includes watch boxes, tools, pouches, tubes, strap rolls, and buckles, as well as bags, clothing, cuffs, bracelets, jewelry, and collector items.
