1675 Seems legit. Serial shows?!

[Tournesol72]

Hi guys. Thanks for letting me in.

I was looking at a 1675 on ebay:

What’s your take on this one?
Should we warn the seller not to display serial #

What bracelet would be correct for a 71 GMT?

Cheers

Its got a caliber 1570 movement
I "thought" the Model 1675 used the caliber 1575 with date and 24hour.

The pictured watch had date and GMT hand, but NO micro-stella screws so surely a 1570 movement.

No, it's a 1575. Very common to see 1570 bridges on them. They are the same movements except for date feature.
So, seeing as the 1675 has the date feature, you know it's a 1575.

Watch looks fine, albeit well worn and overpriced IMO.

The movement has no micro-stella screws - does that not make it a 1570?

I read here (maybe TOOLS/Larry)
The 1570 was introduced in 1965 and has balance assembly rolex p/n 8106 with Breguet hs running at 19800 bph.
Cal 1575 was the same thing with date.
Cal 1575 GMT has date and 24h hand.
All are chronometer grade movements.
Many date and GMT movements are stamped 1570.


But I am sure the 1575 has micro-stella screws but the 1570 has not.

I agree 100% movement is genuine, but I am confused to that.

Thanks

Yes, it does. The balance wheel is in motion in the pic, blurring the screws.

Who told you that?

I do NOT believe these are running, / hiding screws

NOR the photo of movement in OPs photo.
I looked very carefully, and although I fully agree its harder to detect, you usually get some "sway" of them

Thanks
