As for the GMT, the Rolex ( 6542 / 1675 / 16 750 / 16 750 / 16 700 / 16 710 / and the latest with the ceramic bezel ).
As for the WT, the Patek ( 5110 / 5130 ).
Nown there are some cool outsiders:
As for the GMT, Ulysse Nardin offers some very interesting models, such as the simple San Marco; or tje exquisite Sonata, without forgetting the Perpetual Calendar.
As for the WT, I would give a special mention to two watches here: The Girard Perregaux WW TC, and the JLC Master Geographique ( the latest one is exquisite ).

...which is that you would like to see both time zones immediately. That's the way that I like it as well, which is why I am strongly drawn to the JLC Geo and Lange 1 Time Zone rather than to the PP (or now VC) style world timers, which are not at all intuitive to me. The VC Overseas Dual time is built on the same concept, although to me a bit less useful due to the absence of a minutes hand on the second time zone.
I also own a UN dual time, but for whatever reason find the display of the hour in the little window less useful.
If you don't need to see both time zones exactly at once, the Reverso Duo/GMT watches are really cool -- two time zones on different sides of the watch, with two entirely different faces. An under-appreciated complication, IMHO.
Have fun choosing, and tell us where you land!

The geographique will show both time zones - a function you mentioned as a preference. It may be my favourite offering from this year's SIHH from all brands. Best,




is a fantastic thing. The prototype in your original post was just my kind of watch. One of those simple yet so useful modifications...
it is my no-nonsense do-everything international travel watch.
For perfection, I would probably go to the Lange 1 Timezone PT, with the Patek 5110P a close second.

Easy to read and quite useful to have an alarm when we travel.

its similar to the Lange 1 timezone as it has a sub dial with hours and minutes for home time and +/- pushers to adjust the hour hand of the main dial. the minute hands adjust together. its suitable for most places except the awkward places that have 1/2 hour differences.

Can I suggest the Vacheron Constantin Patrimony Traditionnelle World Time, a SIHH 2011 novelty?
You can find details in this article posted by WHL, the VC forum moderator:

Ciao!




The dual time zones are independent and the minute hands in each of the timezone dials can be set independently without any constraints. Thus you can set the times even one minute apart if you wish to...
Two other good choices are Dubey & Schaldenbrand Aerodyn Duo which comes with independently operating twin time zone dials, date subdial and a 24 hour indicator (most valuable when travelling). A real value-for-money watch.
Parmigiani Hemisphere offers the same convenience, but with two 24 hour indicator dia ls for added convenience and a Manufacture movement to boot and ofcourse the premium pricing!!!
IMHO it would be preferable to stay away from pure GMT watches as any time difference under 60 minutes between your foreign and local time zones becomes impossible to manage.
The world time watches with the 24 zones are also not the best of options given the limitations of one hour increment as well as the summer time setting issues.
I am not sure about the new Vacheron world time which addresses the half hour issues, but looks quite cluttered in the bargain. Same for Andersen's world time watch ( tribute Fleming)
Cartier's world timer has just entered the fray. But not my cup of tea.
