The White Lume Dial

The White Lume dial reverses the usual arrangement. Instead of luminous markers on a dark ground, the entire foil surface is luminous BGW9 Grade A. By day it reads as a clean white dial with black PVD indexes and hands drawn sharply against it. By night the whole face glows and the markers turn to silhouette — the display simply swaps its polarity and stays readable. It is the Expedition's legibility argument carried to its end.

Expedition

Grade 5 Titanium Case

The Straum Expedition case is Grade 5 Titanium, redesigned around a 38.2mm bezel. A broader flank profile deflects impacts away from the crystal, a stepped bezel reduces the surface area of the highest plane of the case, and an enlarged screw-down crown is sized for cold or gloved hands. Beneath it sits a Fluor Orange indicator, visible whenever the crown is left unscrewed.

The Straum Coupling

Machined from Grade 5 Titanium, the Straum Coupling is a push-button quick release for fast, tool-free strap changes, housed in the midlink.

Caseback and movement

The Expedition runs the G100 by La Joux-Perret—an automatic movement with date, 24 jewels and a 68-hour power reserve, regulated in-house. It sits behind a closed screw-down caseback etched with a lone hiker beneath a star-filled sky.

The Capsule

Every Straum Expedition comes bundled with a Straum Capsule, designed to keep your watch protected against the elements and is machined from a single block of aluminum and surface treated with a HA1 Hard Anodization process to increase durability.

Press corner

Straum flips its nature-inspired concept on its head and, in the process, makes one of the best adventure-ready watches in recent memory.
