OLTO-8 uses several very different ways to express mechanical watchmaking. This guide helps you start with the type of experience you want rather than browsing dozens of models without context.

Family What defines it Typical starting point
ROTO Wandering-hour display built on a modified Miyota 9039; slim 38 mm case and 42-hour power reserve on the current ROTO specification. For buyers who want an unconventional display in a relatively compact case.
KING 3D satellite-hour architecture with a modified Miyota 9039 and OLTO-8 module; 38-hour power reserve and 5 ATM water resistance on the current KING specification. For buyers who want more mechanical theatre and a stronger visual statement.
Chrono Gate Jumping-hour display with guilloché dial; current versions use the OT.G102 with OLTO-8 module and offer multiple configuration levels. For buyers who prefer a dressier jumping-hour concept and customization options.
REEF Skeleton-inspired marine design with strong lume and an open visual character. For buyers who want an expressive mechanical look at a more accessible entry point.
TIDE-X Skeleton mechanical diver with the SL2204B automatic movement, 42-hour power reserve and 200 m water resistance on the current specification. For buyers who want a sportier watch with serious water resistance.
