Minute Repeater GMT vs GMT Minute Repeater

 

Some Minute Repeaters display a second time zone, but can only chime the local time: let's call them Minute Repeater GMTs.


But other Minute Repeaters do not only display a second time zone: they can also chime the second time zone or the local time on demand: let's call the GMT Minute Repeaters.

Here's an example of each.

A/ Minute Repeater GMT

Parmigiani Fleurier Toric Minute Repeater GMT, ref. PF000463 (2003)

42 mm platinum case & manual cal. 250 (33 jewels) with radial date (set via the pusher at 2 o'clock), second time zone at 3 o'clock (set via the pusher at 5 o'clock) and small seconds at 9 o'clock

B/ GMT Minute Repeater

Panerai Radiomir 1940 Decimal Repeater Carillon Tourbillon GMT, ref. PAM00600 (2016)

49 mm polished Goldtechβ„’ case powered by caliber P.2005/MR (28,800 vph, 59 jewels, twin barrels with 4 days of power reserve) featuring:
  • decimal carillon repeater complication (three gongs with three hammers)
  • second time zone (home time) at 9 o'clock
  • a day/night indicator of the second time zone at 3 o'clock 
  • power reserve on the back
This watch can chime both home & local time on demand: one can switch between the two with the pusher set into the crown (making the watch look a bit like a monopusher chronograph). The red dot indicator under the second time zone sub-dial at 9 o'clock shows whether home time (HT) or local time (LT) is selected for chiming. The activation button of the repeater is placed at 8 o'clock.

As this watch shows only whole hour offsets from the second time zone, the two chiming sequences are identical except for the hours: so, there was no need to duplicate sets of hour, 10-minute, and minute cams: "only" two sets of hour striking mechanisms were needed.
