How does Worldtimer work for Summer/Winter time?

 By: CastorKrieg : January 14th, 2020-01:10
So this has been bugging me for a few years now and since 5230G is a VERY nice watch I need to be educated. Are all the cities present on the dial switching between summer/winter time? Or only some of them, meaning that effectively some of the timezones are wrong 50% of the time?

Add to that the fact EU is now deciding on which timezone to stay in (each country is given a choice of deciding - once you pick you stay in that timezone for the whole year) - will Patek make dial changes in 2-3 years to account for that?

No matter how beautiful I cannot bring myself to wear a watch with a complication that will turn out to be 'wrong' 50% of the time.

Indeed, Patek does not provide Daylight saving time adjustment on their WT.

I believe JLC does, with little "sun" icons next to each city that adjusts.

Saw the JLC, interesting solution

I guess while practical it will not sit well with the way Patek designs the dials - I agree the 5230G looks much 'cleaner'. But also this will be outdated as well - Paris, London, and Athens are all on the dial with Summer/Winter settings, which will become moot next year.

I believe

Brietling does the same. And as others have pointed out, countries aren’t even aligned on the day they do the switch.

I like the VC overseas world timer. IMHO it’s pretty and functional

So far no ...

That's what i have been told when i picked up mine in Paris (and yes France is switching between Summer and Winter times).
If i recall well the dial / hour disk is made for winter time and indeed might have 1 hour issue during summer.

I believe Patek will have the capability to change the dial once every one has decided which time zone they will be, after i m wondering if those "wrong" dials will not become collectors ...

I guess I will wait a few years

To have the situation cleared at least in respect to Europe.

Never worried me at all.

But if you want to be accurate you would need to take account of the fact that the DST changes are not all made on the same day - so even if you had a dogs dinner of a dial that allowed for all the time zones (of which there are more than 24) and also DST savings you still couldn't rely on the watch for 100% accuracy.
I enjoy it for what it is  - and artistic and mechanical marvel.

That's a way to do it! [nt]

It’s a beautiful art piece more than a tool [nt]

This is a point I am surprised so many people look over.

We are very critical when it comes to the accuracy of watches. We look at small fine details of watches in depth. Movement edges sharpness, font ink etc etc!

And yet nearly everybody is fine with a watch that is wrong 50% of the time!! It would kill me! The WT function is not complete, and hence is not an accurate complication for me.

JLC had the best solution that I had seen. Also Glashutte Original with the Cosmopolite.

However to be as accurate as possible, it is difficult to have a clean dial. 

That is why I think a dual time is a good compromise and the JLC Master Geographic gives the opportunity to change the second timezone by city.

Lol....Good one πŸ‘πŸ» [nt]

It does not.

The watch will be off for certain time zones that participate in DSL. This complication came out in 1937 and I believe they want to stay with the historically accurate version of their world timer.
