説明
Anyone who works across two time zones develops a private arithmetic: add six, subtract three, remember whether the other office is already asleep. The Dual Meridian removes that calculation. A GMT complication tracks a second time zone on the same dial, and because the movement is mechanical rather than quartz, the watch keeps running from the motion of a wrist instead of asking to be charged.
The specification is honest about what it is: a 40 millimetre stainless steel case, 14 millimetres thick, crowned with sapphire crystal rather than mineral glass, on a 20 millimetre stainless bracelet. The movement winds automatically and can be hand-wound when it has been off the wrist, the calendar is complete with an automatic date, and the hands are luminous for the hours when the arithmetic matters most. Ten bar of water resistance covers swimming and rain without inviting a dive profile.
What separates a GMT watch from a travel gadget is the second hand's purpose. It is not decoration; it is a fixed reference to the place you are not, and a mechanical one keeps that reference without a battery, an app, or a notification. That is the whole argument, and it is a good one.
Two time zones. One dial. No battery.

Who Wears a GMT
Worn by people whose day is split between a home office and an overseas client: exporters in meetings before the European morning, engineers coordinating with a factory floor eleven hours ahead, families with a child studying abroad. It suits a shirt cuff and a site visit equally, and the 10 bar rating means it does not need to come off for a swim. Where a smartwatch reports everything and demands charging, this one reports the two things that matter and runs on movement.
Ownership Questions
Q: Does the GMT hand move independently?
The GMT complication provides a second time-zone reference on the dial. Set it to the zone you need to track and it tracks that offset while the main hands show local time.
Q: Is the crystal really sapphire?
Yes, the dial window is sapphire crystal, which resists the everyday scratching that mineral glass accumulates. It is harder than mineral glass and reads more clearly at an angle.
Q: How accurate is a mechanical movement?
Mechanical movements run within a tolerance rather than to the second, and that tolerance depends on position and temperature as much as on the movement itself. Expect it to need periodic setting rather than daily correction.
Q: Do I need a watch winder?
Not if you wear it regularly, because the automatic winding keeps the mainspring charged through normal motion. If it sits for weeks, hand-wind it before wearing rather than relying on a winder.
Q: What does 10 bar water resistance allow?
Swimming, showering and rain are within the rating. High-velocity water, diving and pressing the crown underwater are not, regardless of how the number is printed on the dial.
Q: Can the bracelet be sized?
The stainless bracelet uses links with a folding clasp and safety catch. A jeweller or a basic link tool can remove links to fit; keep the removed links with the watch.
Q: Is the GMT hand adjustable without a tool?
It is set through the crown, following the winding and setting sequence in the supplied instructions. Set the local time first, then offset the GMT hand to the second zone you need to track.
Q: How often does a mechanical watch need servicing?
A mechanical movement benefits from periodic servicing rather than running indefinitely without attention. Follow the interval recommended for the movement and have the case seals checked whenever water resistance matters.
