I'm kind of embarrassed for spending this much time on TRF and not noticing this sooner. Perhaps I've been in denial about my beloved root beer, an impulse buy from a couple years ago.

In any case, my 1675/3 changes its date slowly, starting at about 10:30pm. Basically, it's just like my wife's Air-King-Date, which has a caliber 1535 and is known to change its date gradually. I thought I remembered reading long ago about some early 1675's having that trait, but...maybe I'm crazy; I can't find anything about that now.

It ticks 5.5 bps, so it's not a 1560/1565 movement. It doesn't hack, so it's probably pre-1972 as I understand. Its 5.2m serial puts it at 1977, so yeah, kind of a red flag there too. It keeps good time, winds like butter, and has a good power reserve.

I remember the seller's pics appearing to have a 1575 movement (with "1570" bridge) as far as I could tell, but I was an even bigger novice at the time so who knows.

Are any 1675's supposed to have the slow, "non-clicky" date change? If not, could it be a symptom of needing a service? Or am I just living in Franken City? Thanks all!

Small matter. Just visit your watchmaker to reposition the hands to make it change exactly at twelve. Takes less than 5 minutes for mine to open the caseback, determine the exact time it changes, remove the hands, repositioned them again and test the exact time changed and finally screwing back the caseback. No worries.

powerfunk · 29 July 2013, 03:04 AM

Well, it doesn't change over "exactly" at any time. It changes slowly throughout 4-5 hours.

landroverking · 29 July 2013, 03:05 AM

Don't think that's right. My 1675 flips over very quirk.

powerfunk · 29 July 2013, 03:19 AM

That's what I thought.

Thanks Jay!

timnik · 29 July 2013, 04:44 AM

My 1967 1675 flips over with an audible click at 7 mins to midnight.

scottb2 · 29 July 2013, 04:59 AM

i had one that flipped never at 12 - i have had other rolex do a similar thing - not that odd

Jim M · 29 July 2013, 05:28 AM

My 1977 Pepsi 1675 changes date in one click at 11:55 most nights that I am up to hear it.

Nice root beer!

powerfunk · 29 July 2013, 09:12 AM

Thanks everyone! I'll get it checked out soon and see if a service restores date "clicking" action.

GeoGio Greece · 29 July 2013, 09:22 AM

Was it always like that, or this is a recent issue ?

To my knowledge, and I have been with threse watches quite a long time, its the first time that I hear that a Rolex changes date over a period of time, that is longer than "just a click".

I very recently checked a 1966 GMT ( pls see my post value of 1967 GMT ), serial 1.49x.xxx, and the date changed with the normal click at 00.02

It takes longer for some of my other makers watches ( Seiko, Ciizen, etc ), but not with Rolex ones.

I expect that the experts here will tell their opinion and experience.

high5 · 29 July 2013, 09:58 AM

no way it takes 4 hours to change date. well i guess it is better than a fake dial.

waspy1 · 29 July 2013, 10:03 AM

Definitely odd. I have a few gmts from 60s and 70s. Some hack, some don't. All flip over in an instant.

high5 · 29 July 2013, 10:12 AM

demand a refund/replacement from the seller if the movement is fake.

Thanks. It was always like this. I know the Air-King-Date (a.k.a. Explorer Date) has a caliber 1535 and the date is supposed to change gradually (like a Seiko). But it sounds like that should not be the case on any other Rolex.

When I first got it I had it opened up and oiled by a local watch shop (that does sell lots of used Pateks and Rolexes), so if it was completely fake inside I think they would know. Serious franken action is obviously a possibility though. In any case, probably time for a legit overhaul and I'll see what's what. Thanks everyone!

samsmart · 29 July 2013, 10:35 AM

Good luck with everything. Its an awesome looking watch for sure, hope the guts are good!

I have a 16750 and recently realized that my date also changes slowly.

cont · 30 July 2013, 01:33 AM

I have this old 1625 that use 1570. and dealing with the same thing.
My watchmaker said it has something to do with the date changer jewel. In my case it was broken, and the watchmaker remove it. the date change function is OK but takes time to completely change. I guess the instaneous date change needs a jewel in order to do so.

Interesting. Sounds like that could be my problem. Thanks!

My 74 changes at 1158 with a click.

harry in montreal · 3 August 2013, 10:51 AM

Mine clicks over sharply. My told Tudors have a 3 hour date sloshover. I think the 1675 needs to be cleaned. No biggie

Andad · 3 August 2013, 11:24 AM

Spare yourself the anguish and have it serviced.
Looks like the date wheel is dragging its feet a bit that's all
The watchmaker can also give you an opinion on whether the watch is a Rolex as you seem a bit concerned?thumbsup:

Gmt1970 · 4 August 2013, 09:07 AM

My 1675 from 1971 clicks round at 12:05 am

Vincent65 · 4 August 2013, 06:16 PM

no - instant

Concord · 4 August 2013, 11:19 PM

If your Rolex has a caliber 1575 (GMT) movement in it, the calendar should change instantaneously. It would be helpful if you could find out which caliber movement you have in your watch. I suppose there is a chance Rolex used a transitional movement in early GMTs based on the caliber 1535 which had the progressive change calendar in it.

powerfunk · 4 August 2013, 11:36 PM

Thanks all, I'll let you know what happens when it's serviced.

It should change with a single click, the watch needs a good service and you'll be good to go.

Shade · 5 August 2013, 02:00 AM

Sounds like some franken innards my friend. But honestly if it doesnt bother you all that much I will just leave it at that. Fooling around with it will only cost you more time and money. I personally think its a great watch!

Concord · 5 August 2013, 03:28 AM

We'll only know when the owner has it opened up and reports the caliber of the movement. Having serviced Rolex watches for over 50 years, I fail to see how it is possible for a quick-change calendar to function as a progressive change type.
