For 1675 with 5 mil serial, it should come with cal 1570 already.

A couple of possibilities..

. Somebody replaced the movement,

. Or the back plate was simply marked 1560 and used by Rolex because back then they didn't really expect anybody to open the watch except a watchmaker; so they used up whatever spares they had..

Err buddy Jason...welcome to this TRF's Rolex webforum...

IF Orchi may ask...from whom have you bought the watch...?

Cal. 1560(or 1565 in GMT) is older n a more expensive n RARE movement...
It's the predecessor of the Cal.1570(or 1575 in GMT/Exp II) movement...

Both of these Cal.movements are based on the earliest Cal.1530 movement...
thus they share many common parts...

Like Buddy Larry has advised you...it is possible that the previous watchmaker...
had to use the Auto-Winding Rotor assembly of Cal.1560 movement to replace...
the faulty one in the watch movement...where the marking is located...

So your watch might still have a Cal.1570 movement...(other than the Auto Winding Rotor assembly change to the one with Cal.movement "1560" marking on it...)

In another likelihood...your watch might have a complete Cal.1560 movement...
BUT Orchi doubts this possibility as the Cal.1560 is more RARE n harder to get...to begin with.

Nevertheless...it would be wise for you to post some pictures of your watch...
n its movement in here for further discussions...

I have a 1675 3.0mil with a Cal. 1560.
It's never been changed or sent to the RSC. I was told that a few 1675 (up to 4.0mil) were still equiped with Cal. 1560.

Err buddy Ben...it's has been recorded in many Rolex publications both...online or off line...
that Rolex ceased to produce Cal. 1560/5 movement by...1965...
with the introduction of Cal.1570/5 movement in the same year...

IF you had bought your 3.0mil case series 1675 since new...with provenance...
n had not any recollection of having service done to the watch...
your 1675 would be the only...1675 with Cal. 1560/5 movement...

On the otherhand...if you had bought the watch used...
it would be difficult to ascertain whether or not...the watch had ever been sent...
for servicing...

The Auto-Winding assembly is prone to wear n tear from heavy usage...or negligence...
It is often changed during service...due to the lose Rotor Blade shaft gotten worn out easily...under those circumstance.

Hence the previous watchmaker could have put in a Cal.1565 Butterfly Rotor Auto-Winding assembly into your watch...

The easiest way to find out whether or not...the movement of your 1675 is indeed Cal.1565...is having the watchmaker check its alternation rating...

The Cal.1560/5 alternates at 18,000 bph...
The Cal.1570/5 alternates at 19,800 bph...

Err buddy Jason...thanks for posting the pictures...which tell a thousand words...

The Auto Winding assembly(where the marking is located) has been changed...
in your 1675 watch...

Your 1675 watch has also an EARLIEST variant of Mk.1 Dial...on a later 5.0mil Case series...

It also has a later replacement bracelet...(can't tell whether it's genuine or not from the picture.)
n an early dated backcase cover...(IV.68)

IF you had bought this watch from a seller named "Cheong"...do remember what the word means...in Cantonese...

Orchi, thank you very much for you wisedom ;)
Is there a way to check if it is a 1560 with the movement's number?
My father serviced the movement a few time since he bought it brand new in '73.
He said he's never changed anything beside gaskets and the crown.
I'd like to get a clear caseback to expose the unusual rotor blade.

Err buddy Ben...RSC may have a clear record of movement nos...
n its date of production...but outside of that...
there has been little or no source of such complete record...

Part of the reason(no accurate independent record) perhaps...
the entire movement or its parts are subject to being replaced...
under heavy wear or negligence(like water damaged which tends to happen)...
just like the same could happen to worn out backcase cover...
or even the entire case(if corroded)...though the latter is less likely.

IF your watch was purchased in 1973...
the watch would have been at least...37 or 38 years of age...
as it might take up to a year for it to show up at the AD sale counter from production...
before it could be sold...

Unless the watch has been in long storage...over those many years...
otherwise there would have been some more parts changed...
besides the gasket n the crown...such as...
its Crystal...main spring...date wheel...etc...
n most likely the Auto-Winding Rotor assembly in particular...
as it's prone to wear out.

So safe always...you could have it placed on the alternator meter...
to check whether...it has 18,000 bph or 19,800 bph...
in order to determine for certainly whether the watch Cal. 1560/5 or not...
