Vivian Ko is a co-founder and the logistics lead of RZE Watches, an independent watch brand based in Singapore that specializes in titanium tool watches. Alongside her husband, Travis Tan, a commercial airline pilot and experienced watch designer, Ko was instrumental in the 2020 launch of the brand, which was originally introduced as Reise Watches.

With a professional background focused on operational execution, Ko brings extensive experience in fulfillment and global distribution to the brand. Prior to the establishment of RZE, she spent five years managing the logistics for multiple successful crowdfunding campaigns in the horological space, overseeing the shipping of thousands of timepieces to international customers. This technical expertise proved foundational to RZE’s business model, which relies heavily on direct-to-consumer distribution and community engagement through platforms like Kickstarter.

At RZE, Ko is often referred to within the company as the “Logistical Ninja,” reflecting her responsibility for ensuring that products move efficiently from the manufacturing stage to the hands of customers. Her role is central to maintaining the brand’s reputation for reliability, complementing the design and engineering efforts led by Tan and the commercial strategies developed by co-founder Clarence Chew.

As a key member of a small, family-run enterprise, Ko’s contributions help define the brand’s commitment to accessibility and sustainability. She is part of the core leadership team that emphasizes the use of durable, aerospace-grade titanium and scratch-resistant UltraHex coating, aiming to create timepieces that serve as long-lasting “adventure companions.” Through her work, Ko remains a vital figure in the operational success and global growth of RZE Watches within the independent microbrand market.
