1675 GMT Hand Stack

[Konrad Bigsby]

Hello all:

I read in these forums that the correct hand stack for a 1675 places the red GMT hand on the bottom below the hour hand.

Just noticed that my (what are supposed to be original hands) do not indicate this as the GMT hand is above the hour hand.

Any idea how this could have happend?

changed in service possibly.. actually most likely. If it has had a non rolex service they might just have put them back on in wrong order.
my 1675 goes from bottom to top ; red hand hour hand minute hand seconds hand.

So the GMT hand rotates twice every 24 hours and the hour hand only rotates once in your case?

nope, GMT is once a day and hour is every 12. Keeps perfect time in both time zones.

[dddrees]

Wrong position but it works correctly?

[Saxon007]

You sure it is a 1675 and not a 16750?

[Konrad Bigsby]

yup, serial 61xxxxx. So a 1979 I presume??

and yes, wrong stack position and works perfectly.

Any GMT masters out there with an opinion or ever see this before?

yes a 16750 haas hand stacked like yours!! came in 1980? could be a crossover , very possible, or just and earlier case to movement too

wow, so now I am super interested in what I have on my wrist. I bought it from my friend who owns Honolulu Time, and is a very trust worthy dealer. I am almost positive that the hands and dial are original. Could the movement be a later service piece?

I assume it would have to be opened up to to be sure?

[toph]

have you checked the case that it says 1675 and not 16750?
Even if it does say 1675 it might never have been used until they started using the upgraded movement on the 16750? Stranger things have happened.
Get the movement checked. Also movement could have been replaced but so woudl dial and hands probably at the same time.
Still a great watch but for peopel like us it nice to know what one has exactly

[toph]

may i add that that dial was used on both the 1675 and 16750.

[Konrad Bigsby]

what about the time adjustment. Is the 16750 GMT non adjustable like the 1675? If I do have a 16750 movement the GMT hand is still non adjustable, just like a 1675.

Yeah, the independent red hand only came in 1983 with the introduction 16760 or Fat lady as its known as it had a thicker case too. it had 3085 movement

GMT 1675 had
1560/5 movement ( 0 on the end is the base movement but denoted with the 5 to reference modification of the date added to base calibre .
then the
1570/5 movement
and the 16750 had a 100m depth rating not 50 m and 3075 movement with a 28.8k bph rate over the 19.8k for the previous cal. 1575

[Konrad Bigsby]

cool, so I may have a transition year? Very exciting and I will get my friend to pull the back off just as soon as I can. Stay tuned and happy to hear from anyone else who wants to chime in.

Much Mahalo!

[toph]

[mike]

Base on the ref. and serial that watch should be a non-quick set calendar.

Is it non-quick set or quickset? That might help understand the movement situation.

A non quick set, case says 1675 and yet the hour hand is on the bottom.

Time to open it up.

The issue here is that the 24H (red hand) is not at the bottom where it is supposed to be.

...yes, correct, but it was an opportunity to post my pictures of a decent one

Yes, that is the issue

[kyle L]

Still trying to figure out how it works perfectly if the hands are stacked wrong...

[Konrad Bigsby]

I am starting to think it may be a transitional year? Maybe a 1675 case with a pre quickset 16750 movement from the factory.

Is this possible?

[soundserious]

here's my 16750 if it helps

[Brad21]

the date font looks off also. doesn't look strong enough..

Not really. The dial feet are different for a 1675 vs. the 16750.

of course you are right but that would make no difference if they just had a 1675 case and stuck a 16750 mov't ,hands and dial on it. This matte dial was laos used on both so from its appearnace it tells us nothing. I dont know if rolex could have done this but thats what he wants too know i think
