SWISS SUPER-LUMINOVA® LUME

Legibility when light disappears.

Applied to the hands, indices, and key dial markers, Swiss Super-LumiNova® ensures the Ocean Series remains readable long after daylight fades. The glow is clean, even, and purposefully balanced — bright enough to perform, refined enough not to overwhelm.

Use the left and right arrow keys to navigate between before and after photos.

UPGRADED MOVEMENTS

Every movement used in these collections has been selected through real-world testing, not trend-watching or spec-sheet comparisons.
For the Master Series V3 and Pro Dive Series, we've chosen the Miyota 8215. It’s reliable, robust, and features hacking functionality, making it even better suited to everyday wear.
For the Ocean Series, a Seiko NH34 automatic GMT movement was chosen where its design and architecture made the most sense for a travel-focused watch.
