About Mk II


In 2002 Mk II was launched as the first company to offer watch parts and customization services for other maker’s watches, such as Luminox and the venerable Seiko Diver series, pioneering a new facet to watch collecting. Building on the success of the quality of our design and workmanship Mk II evolved into an American watch company specializing in custom, Japanese and Swiss Made tool watches sold exclusively under the Mk II brand.

“Mk II/Mk 2/Mark 2” is widely used by military organizations to designate the second generation or iteration of a tool or piece of equipment. We selected the designation “Mk II” as our trademark to represent our dedication to utilitarianism, reliability, and timeless styling. Mk II encapsulates our endeavor to build an inclusive brand; rooted in value and substance. We’re driven by our mission  to build watches that will serve our customers with distinction and earn a place in their family’s history.

our principle

Good design is the physical embodiment of a philosophical perspective. Each Mk II timepiece is engineered around a function and purpose. When we work from a vintage reference design we delve into the philosophy and intent behind its different elements in order to renew its purpose rather than merely re-creating it. This understanding guides our contributions when styling needs to be updated to accommodate modern techniques, materials, aesthetics, or other improvements all the while preserving the essence of the design.


We reference vintage designs because those are the designs that we are passionate about and want to see renewed so that they can tell their story through a new generation. We re-work and reimagine the designs in an effort to renew or create a timeless quality in the hope of extending the design’s influence into the future. The ultimate goal is for our timepieces to earn a place in your history. Toward this goal it must transcend fad or fashion.


For a piece to become timeless it has to survive the test of time from a design as well as a functional aspect. This is why we focus on quality and execution. A reputation built on an unrelenting commitment to quality is why our watches have found their way to Afghanistan, Iraq, and other equally pleasant locales. Attention to the details invites customers to build a lasting relationship with a timepiece. A well designed tool will be used. A trusted tool is something that becomes a part of you.



The Mk II utilitarian design aesthetic permeates everything that we do and in a nutshell defines our personal philosophy. The workshop is outfitted with state-of-the-art testing equipment and tools. Aside from those essential pieces of equipment the workshop itself exemplifies a workspace with every priority being given to sourcing quality components and the tools that enable us to realize our dedication to superior workmanship.
