I would like to know when Rolex last used this type of rotor for the 1675 GMT.
Although, I have a 1675 from 1973 with such rotor, I thought Rolex had switch to a plain rotor in the early 70's

Oops is should say ROTOR in the title.

Anyone has any idea about this type of rotors and when Rolex stopped using them?
Seem odd that I found it in my 1973 GMT.

is the bridge of the winding weight devise marked, (1530>1535>1555>1560>1565>)

does the watch hack?

Hey Blaine,

The bridge is marked 1560. As for hacking I don't remember if it does or doesn't, The crown fell off last week.

If it has an older cal. 1560/5 that would explain the rotor.

assuming that the movement serial # starts with a (D)

can you take the watch to your watchmaker and check the speed
18000 or 19800>>>>>>>>>>1560/5 or 1570/5

i'm thinking like you, smooth top rotor for 1973(1570/5)

a wise man shared with me that all 15 series movement interchange!
yours may of been changed??? (automatic winding devise)

memory?? i don't believe that 1560/5 ever hacked

Blaine,
The movement serial is D357431.

We've had this GMT since '74. To my knowledge the movement was never changed, though. Rolex replaced the all red 24hr hand with a regual hand... It was serviced in 81 and 91.

I'm going to take it to my watchmaker to install a new crown.

Ben,
check the speed. slow(18000) 1560/5 fast (19800) 1570/5.

its either a 1560/5 that ended up in the watch in 1973 or
a 1570/5 with a 1560 top

hack? 1570 after 1972, 1560 i don't thick it ever did.

cheers
