Finished for the loupe.

Every surface is finished by hand before assembly. Brushed where it should stay quiet, polished where it should take the light. Under magnification it is still calm.

The Traverse GMT · in four details

01 — Home time

Two times, one glance.

The red arrow makes one turn every 24 hours and points to home time on the bezel. The hour hand jumps in single hours to wherever you land; the minutes never stop.

02 — The bezel

Night above, day below.

The ceramic insert is split exactly in half: glacier blue from 18 to 6, ember red from 6 to 18. Read the colour under the arrow and you know whether it is night at home.

03 — The emblem

The peak at twelve.

The 12 o’clock index is cut like a sérac: one facet polished, one facet lumed. The same peak is engraved on the crown and on the clasp.

04 — Power reserve

Seventy-two hours.

Traverse GMT

A dual-time instrument for people who live in two places at once. One hand keeps the hour where you stand; the red arrow and the 24-hour bezel keep the hour you left behind.

All references

Lumière Glacier

Lights out.

Every index, both hands, the peak at twelve and the triangle on the bezel are filled with a blue-green luminescent compound, applied by hand in three layers. Charge it under a lamp for ten minutes and the dial stays readable through a polar night.

On the name

A sérac stands perfectly still while the glacier moves beneath it.

Night flight

Home time, carried across the night.

Before you leave, set the red arrow to the hour at home and leave it there. Over the ocean, at the gate, awake at four in a hotel room — one look gives you the time where someone is waiting.
