Available Finishes

Brushed and Polished: This finish combines a sleek, matte brushed surface with shiny polished edges and a recessed logo plate. It provides a balanced look that complements both modern and classic watch designs. This finish is ideal for those who appreciate subtle sophistication and it pairs well with brushed or mixed-finish watch cases, adding a touch of elegance without overpowering the overall aesthetic.

Full Mirror Polish: The full mirror polish finish is the epitome of luxury and refinement. With its high-gloss, reflective surface, this finish gives a sense of high-end craftsmanship. Perfect for formal or dress watches, it matches seamlessly with high-polish watch cases, creating a striking appearance.

Sandblasted: The sandblasted finish offers a unique, matte texture that stands out for its understated, rugged charm. It’s particularly suitable for tool watches or those with a sporty, utilitarian design. This finish complements matte or bead-blasted watch cases, providing a robust and cohesive look.

Black: Our PVD Black finish features a sleek, modern black coating applied through Physical Vapor Deposition (PVD) technology. This finish is ideal for contemporary watch designs and adds a bold, stylish edge to any watch. It pairs exceptionally well with black or dark-toned watch cases, enhancing the overall stealthy, sophisticated aesthetic.

Antique Bronze Effect: Our PVD Antique Bronze effect finish provides a distinctive, aged look that adds character and heritage. It’s perfect for vintage-inspired or heritage watches, giving them an authentic, timeless appeal. This finish pairs beautifully with bronze or similarly aged watch cases, enhancing the overall vintage vibe and adding a unique touch to your watch.
