However, these are very different devices and not primarily meant as a watch. The Garmin Fenix, for instance, and some Suunto models as well. We found wrist devices, which could probably double as watches, able to do so. So even if there would not be GPS reception (inside a building or a plane), DST will be initiated automatically by the watch.ĭo watches exist which do change time zones automatically? DST information is not sent to the watch by satellite but is included in a database inside the watch. How about Daylight Saving Time? Does the wearer have to initiate this change in time manually as well? Another ‘no,’ however, this time more positive.
#Casio time zones manual
Upon further investigation, it pointed out that these watches as well require manual intervention by the wearer to change the time to the actual one at the present location.
We did a review of one of them, the GPW-1000RAF, here. We knew that, besides Seiko and Citizen, Casio has GPS controlled watches as well. Mentioned GPS-controlled watches then ‘know’ their position on earth and are able to determine the right time zone at that location.ĭetail of the Casio GPW-1000RAF, showing that it has GPS reception on board However, a slight manual intervention is the only thing that must be done to receive the absolute precise time. So with these watches, there’s no such thing as sailing at the ocean or hiking through a desert and seeing the time of the watch change because you just entered another time zone. A wearer intervention is needed to have the watch contact the GPS signal to change the time when needed. When flying from Amsterdam to London, just leaving the airplane won’t initiate these watches to change the time automatically. Neither the Seiko Astron – like the one we reviewed here – nor a Citizen Satellite Wave watch will automatically change the time when the wearer enters a different time zone. Only models after 2015 can also receive GPS position information and thus can automatically set the time to the correct time zone. So we made some phone calls and got the answer.Ĭitizen Eco-Drive Satellite Wave F100 (2014). However, do these models automatically change the time when I step off the plane in a different time zone? Or do they require manual operation to do so?Īn interesting question, for which we couldn’t find an answer at the mentioned companies’ websites as well. Therefore I’m looking at Seiko Astron and Citizen Satelite Wave models, which get the time from GPS satellites. It would be nice if I could have a watch which does the same. Most of the time, my phone changes to the local time automatically as soon as I receive a carrier’s signal in my destination country. I am a frequent traveler and am looking at GPS time-controlled watches. You Asked Us: Do GPS-controlled watches automatically change time zones? Jerôme is a frequent intercontinental traveler and is looking for a watch that he doesn’t have to set when stepping out of a plane in another part of the world. This week we’re answering a question from globetrotter Jerôme about GPS-controlled watches.
