How a replica pilot watch shows a second time zone
A pilot watch with a GMT hand shows two time zones at once. The 24-hour hand points to a 24-hour scale on the bezel or the dial ring. The main hands show local time. Read the second zone by matching the 24-hour hand to the printed scale. The bezel turns in 24 clicks on most models. One click is one hour.
Two movement layouts exist. A true GMT movement lets you jump the hour hand in one-hour steps without stopping the watch. Rolex uses this layout in calibre 3186 and calibre 3285. A caller GMT, also called an office GMT, quick-sets the 24-hour hand instead. The ETA 2893-2 and the Sellita SW330-1 follow that pattern. Most replica GMT watches sold under $300 use the caller layout.
Movements found in replica GMT watches
- Shanghai 3186 clone: hour hand jumps in one-hour steps. Common in copies of the GMT-Master II.
- Modified ETA 2836-2 with a GMT plate: caller GMT. Typical of 2015-era batches.
- Sellita SW330-1 and ETA 2893-2: Swiss-made, caller GMT, 42-hour power reserve, 25 jewels.
- Seagull ST2130 base: no 24-hour hand, no GMT function.
Setting the two zones
- Set the 24-hour hand to UTC first.
- Turn the bezel so the target city sits at 12 o'clock.
- Set the main hour hand to local time.
- Check the date flip. Most of these movements change the date between 22:00 and 02:00.
Points to check on the watch
Bezel action: 24 clicks with no play. Hand alignment: the 24-hour hand should sit on an index at each hour. Date window alignment at 3 o'clock. Replica cases measure 40 mm or 42 mm depending on the reference. Water resistance is not tested on replicas. Do not swim with one.
Prices run from about $120 to $500 for a GMT replica. Swiss-movement versions start near $400. Service intervals are shorter than on a genuine watch. Many watchmakers will not service a counterfeit movement.
Import of counterfeit goods into the US is barred by 19 U.S.C. § 1305. Customs can seize a shipment. That risk does not depend on the price paid.
